Fastener Finishes & Coatings: The Complete Guide

Professional Fastener Finishing Services for Nuts, Bolts, Washers & Bespoke Components

Note that not all of these finishes are available to Trojan Special Fasteners and a number of unmentioned ones are. So, if in doubt, please always ask us and we'll find out if our subcontractors can finish your ordered fasteners in the way you need and want.

Choosing the right finish for your fasteners is just as critical as selecting the correct material, thread form, or dimensional tolerance. The coating or finish applied to a nut, bolt, washer, or bespoke component directly determines its resistance to corrosion, assembly performance, operational durability, torque characteristics, and final appearance. At Trojan Special Fasteners, we supply precision-manufactured fasteners across our complete size range – M3 to M52 in metric, 2BA to 2" in Imperial (BSW/BSF), and #8 to 2.1/4" in Unified (UNF/UNC) – with a comprehensive selection of high-performance finishes tailored to your exact specification.

Whether you require standard electroplated coatings for general engineering, heavy-duty hot-dip galvanising for outdoor infrastructure, or specialist zinc flake systems for automotive and aerospace applications, we work with trusted subcontractors to deliver finishes that meet international standards and exceed your technical requirements. All finishes are available in both left-hand and right-hand thread configurations, with selected coatings suitable for oversize thread applications.

Our Core Finishing Processes

  • Galvanising - For ultimate durability in harsh outdoor and marine environments, discover our hot-dip galvanising process. Ideal for structural fasteners, infrastructure projects, and applications requiring long-term corrosion protection to ISO 10684 and BS EN ISO 1461.
  • Phosphating - Explore our wear-resistant manganese phosphate (Parkerising) and paint-base zinc phosphate coatings on our phosphating page. Excellent for high-friction applications, pre-paint treatment, and oil retention in automotive, military, and industrial assemblies.
  • Zinc Flake Coating - Learn about high-performance, non-electrolytic coatings like GEOMET®, Magni, and Dacromet® on our zinc flake coating page. These coatings eliminate the risk of hydrogen embrittlement, making them suitable for high-tensile fasteners (Grade 10.9, 12.9) and critical aerospace applications to ISO 10683
  • Delta Protekt & Delta Tone – Zinc flake alternatives offering thin, uniform coatings with excellent corrosion resistance and no hydrogen embrittlement risk.
  • Zinc Plating - Discover this versatile and cost-effective electroplated finish on our [zinc plating pagehttps://www.trojansf.co.uk/zinc-plating]. Provides excellent corrosion resistance with bright, yellow, black, or clear chromate passivations to ISO 4042, ASTM B633, and BS 7371.
  • Black Oxide (Blackening) – An economical conversion coating providing mild corrosion protection and an attractive matte black finish. Reduces light reflection and is ideal for military, firearms, tools, and decorative applications.
  • Nickel Plating – Bright nickel, electroless nickel, and nickel-phosphorus coatings provide excellent corrosion and wear resistance. Suitable for electrical, marine, and high-temperature applications.
  • Tin Plating – Offers superior solderability and non-toxic corrosion protection, making it ideal for food processing equipment, electrical assemblies, and marine fasteners to ASTM B545.
  • Electroless Nickel Plating (ENP) – Provides uniform coating thickness on complex geometries with excellent hardness, wear resistance, and corrosion protection. Popular in aerospace, oil & gas, and precision engineering.
  • Passivation – Chemical treatment for stainless steel fasteners to enhance corrosion resistance by removing free iron and promoting the formation of a protective oxide layer (ASTM A967, AMS 2700).
  • Xylan & PTFE Coatings – Dry-film lubricant coatings combining low friction with corrosion protection. Ideal for high-torque, high-temperature, and anti-seize applications.

Self Colour Finish (Uncoated/Bright/As-Manufactured)

For applications where no specific protective coating is required, fasteners can be supplied in their 'self colour', 'bright', 'black', or 'as-manufactured' condition. This means the parts are supplied directly from production with only a light protective oil applied to prevent corrosion during transit and storage. Self colour finish is common for:

  • Indoor assemblies with low corrosion risk
  • Components that will be painted or coated post-assembly
  • High-tensile fasteners (Grade 10.9, 12.9) where coating is not recommended
  • Prototype and development work
  • Cost-sensitive applications

Note: Self colour finish provides minimal corrosion protection and is not recommended for outdoor, marine, or high-humidity environments.

Why Do We Plate or Coat Fasteners?

Applying protective coatings and finishes to fasteners delivers multiple engineering and operational benefits:

  • Forms a Protective Barrier – Many industrial electroplating processes create a sacrificial barrier on the substrate that protects the base metal against atmospheric corrosion, chemical attack, and galvanic reactions. Plated parts can last significantly longer, need less frequent replacement, and perform reliably under extreme conditions.
  • Prevents Corrosion & Oxidation – Zinc, zinc alloys, cadmium, and other coatings act as a sacrificial anode, corroding preferentially to protect the underlying steel. This is critical in marine, automotive, construction, and outdoor applications.
  • Reduces Friction & Prevents Galling – Coatings such as zinc-nickel, cadmium, and PTFE-based finishes improve lubricity, reduce installation torque, and prevent thread galling and seizing, particularly important in stainless steel assemblies.
  • Increases Hardness & Wear Resistance – Electroplating with nickel, electroless nickel, or hard chrome makes brittle or soft materials stronger and more durable. Plated surfaces are less susceptible to damage when struck, dropped, or subjected to abrasive environments, increasing component lifespan.
  • Increases Thickness & Build-Up – Certain plating processes, such as electroless nickel and copper, can be used to restore worn or undersized components, improve overall quality, and extend substrate longevity.
  • Enhances Appearance – Decorative finishes such as bright nickel, chrome, brass, and black oxide improve aesthetics for furniture, architectural fittings, consumer products, and point-of-sale displays. A cheaper way to achieve a premium appearance than manufacturing from solid precious metals.
  • Promotes Adhesion for Multi-Layer Coatings – Copper plating provides a smooth, uniform surface finish ideal as an undercoating to facilitate adhesion with additional coatings such as nickel or chrome in multi-layer systems.
  • Prevents Tarnishing – Some electroplating types protect against premature tarnishing in metals like brass, copper, and silver. Products such as silverware, electrical contacts, and decorative hardware retain their attractiveness and hold their value over time.
  • Conducts Electricity – Silver, gold, and nickel plating enhance electrical conductivity, making them indispensable in electronic components, PCB hardware, telecommunications equipment, and battery terminals. Cost-effective and efficient conductivity solutions.
  • Resists Heat – Plating processes such as gold, zinc-nickel, electroless nickel, and ceramic-based coatings can withstand extremely high temperatures. These protect engine parts, exhaust components, and industrial equipment from thermal damage, extending their operational lifespan.
  • Absorbs Light & Energy – Black electroless nickel and black oxide finishes absorb light and energy, ensuring compliance with industry standards in aerospace, automotive, aviation, optical instruments, and solar energy applications.
  • Ensures Standards Compliance – Many industries mandate specific coating standards (ISO, ASTM, BS, DIN, DEF STAN, AMS) for safety-critical applications in aerospace, automotive, rail, oil & gas, and defence sectors.

Why do we plate or coat fasteners?

Feature Benefit Description
Absorbs Light & Energy Ensures compliance with industry standards Black electroless nickel plating absorbs light and energy essential to many manufacturing processes in industries such as aerospace, automotive and aviation.
Conducts Electricity Cost effective and efficient conductivity solution Silver plating can be used to enhance electrical conductivity which makes it useful in the manufacture of electronic components.
Enhances Appearance A cheaper way to improve aesthetics Jewelry is often plated with a thin layer of a precious metal to make it more desirable.
Forms a Protective Barrier Plated parts can last longer and need to be replaced less frequently, and are more likely to hold up under extreme conditions. Many types of industrial electroplating create a barrier on the substrate that protects it against atmospheric conditions such as corrosion.
Increases Hardness Plated surfaces are less susceptible to damage when struck or dropped, which can increase their lifespan. Electroplating is sometimes used to make brittle materials stronger and more durable.
Increases Thickness It improves overall quality and increases longevity of the substrate. Palladium plating is becoming an increasingly popular choice in manufacturing processes where extreme thickness is required.
Prevents Tarnishing Products such as silverware retain their attractiveness and hold their value over time. Some types of electroplating protect against premature tarnishing in certain kinds of metals and also reduce the likelihood of scratching.
Promotes Adhesion It provides a smooth and uniform surface finish. Copper plating is an ideal solution for providing an undercoating that facilitates adhesion with additional coatings.
Reduces Friction Nickel plating improves performance and reduces premature wear and tear. Nickel plating can reduce the build-up of friction in certain materials such as electrical connectors.
Resists Heat Plating with these metals protect engine parts and components from damage caused by extreme temperatures, which can increase their lifespan. Plating processes such as gold or zinc-nickel are capable of withstanding extremely high temperatures.

Material Compatibility & Substrate Considerations

Not all finishes are suitable for all base materials. Critical compatibility factors include:

  • Alloy Steel (Grade 8, 10, 12)hydrogen embrittlement risk with electroplating; zinc flake coatings preferred for Grade 10 and above
  • Aluminium – Anodising, chemical film (Alodine), or dry-film lubricants
  • Brass & Bronze – Limited coating options; typically polished or lacquered
  • Carbon Steel – Compatible with most finishes (zinc, galvanising, phosphating, nickel, chrome, black oxide)
  • Stainless Steel (303, 304, 316, A1, A2, A4) – Typically passivated rather than plated; PTFE/Xylan coatings for anti-galling

Hydrogen Embrittlement Prevention

High-tensile fasteners (hardness ≥320 HV, typically Grade 10.9, 12.9, and case-hardened components) are susceptible to hydrogen embrittlement during electroplating processes. To mitigate this risk:

  • Specify zinc flake coatings (GEOMET®, Magni, Dacromet®) which eliminate hydrogen absorption
  • Request baking/de-embrittlement heat treatment within 4 hours of plating (per ISO 9588, ASTM F1940, DIN 50969-2)
  • Use mechanically applied coatings (hot-dip galvanising, zinc flake) instead of electroplating
  • Specify lower-strength substrates where possible
  • Request process certification and batch testing

Important: Even with baking, electroplating cannot completely eliminate hydrogen embrittlement risk in high-tensile fasteners. For safety-critical applications, specify zinc flake or mechanical coatings.

Coating Thickness & Thread Tolerances

Coating application increases the effective diameter of external threads and decreases internal thread diameters. Typical coating thicknesses:

  • Electroplated Zinc: 5-15 microns (0.0002"-0.0006")
  • Hot-Dip Galvanising: 45-85 microns (0.0018"-0.0033")
  • Zinc Flake: 6-12 microns (0.00024"-0.00047")
  • Electroless Nickel: 12-25 microns (0.0005"-0.001")
  • Cadmium: 5-12 microns (0.0002"-0.0005")

To maintain thread gaugeability after coating, we can supply:

  • Oversize external threads – Pre-plating undersize manufacturing
  • Oversize tapped nuts – Post-coating tapping to restore thread fit
  • Thread class adjustments – Specifying appropriate tolerance class for coated fasteners

Consult our technical team for coating thickness recommendations for your specific assembly torque requirements.

Frequently Asked Questions About Fastener Finishes

Q: What is the best finish for outdoor applications?

A: Hot-dip galvanising (ISO 10684) or zinc flake coatings (ISO 10683) offer the longest service life in outdoor, marine, and corrosive environments. For structural fasteners, hot-dip galvanising is typically specified to BS EN ISO 1461.

Q: Can high-tensile fasteners (Grade 10, 12) be zinc plated?

A: Electroplated zinc is not recommended for Grade 10 and above due to hydrogen embrittlement risk. Specify zinc flake coatings (GEOMET®, Magni) or mechanical galvanising instead. If electroplating is essential, rigorous baking and testing per ISO 9588 and ASTM F1940 are mandatory.

Q: How do I specify a coating on my drawings?

A: Use standard callouts such as "Zinc Plate per ISO 4042 – Fe/Zn 8 c" or "Hot Dip Galvanise per ISO 10684". Include coating thickness, passivation type (clear, yellow, black), and any special requirements (e.g., "with post-plate baking" or "tap oversize").

Q: What is the difference between galvanising and zinc plating?

A: Zinc plating is an electroplated coating (5-15 microns) applied in a bath, offering good corrosion protection and tight dimensional control. Galvanising is a hot-dip process (45-85 microns minimum) providing a much thicker, more durable coating for long-term outdoor use, but with rougher surface texture and looser tolerances.

Q: Are all finishes available on all fastener sizes?

A: Most finishes are available across our full M3-M52 metric and 2BA-2" imperial range. However, some processes have practical limitations – for example, hot-dip galvanising is not recommended below M8 due to thread fill issues, and some specialist coatings may have minimum batch quantities. Contact us to confirm availability for your specific requirement.

Q: What is the lead time for finished fasteners?

A: Standard finishes (zinc plate, galvanising, phosphate) typically add 7-14 days to manufacturing lead time. Specialist coatings (zinc flake, electroless nickel) may require 3-4 weeks depending on subcontractor scheduling and batch consolidation. Urgent requirements can often be accommodated – please enquire.

Q: Can you match a finish from a sample or competitor product?

A: Yes, send us a sample and we'll analyse the coating type, thickness, colour, and texture to replicate it. We can cross-reference competitor specifications and provide equivalent or superior alternatives.

Q: Do you provide certification and test reports?

A: Yes, we can provide full material traceability certificates, coating thickness reports, salt spray test results, torque-tension data, and compliance declarations to customer-specific or industry standards. Specify certification requirements at quotation stage.

Q: What if I need a finish not listed on this page?

A: We work with a network of specialist subcontractors offering exotic coatings including PTFE (Xylan), ceramic, silver, gold, electroless nickel, anodising (aluminium), and bespoke multi-layer systems. Contact our technical team with your requirement.

Q: Can stainless steel fasteners be plated?

A: Stainless steel is typically passivated (ASTM A967, AMS 2700) rather than plated to enhance the natural corrosion resistance. For lubricity and anti-galling properties, dry-film lubricants (PTFE, Xylan) are recommended. Electroplating stainless steel requires special surface preparation and is rarely specified.

Q: What is 'yellow zinc' versus 'clear zinc'?

A: Both refer to zinc plated fasteners with different chromate passivation topcoats. Clear (also called 'blue' or 'bright') offers moderate corrosion resistance with a silvery appearance. Yellow (also called 'gold' or 'dichromate') provides enhanced corrosion protection with a golden-yellow tint. Black chromate offers the best corrosion resistance with a dark appearance. Note: Traditional hexavalent yellow chromate is now largely replaced by RoHS-compliant trivalent chromates.

Q: Are your finishes RoHS and REACH compliant?

A: Yes, all standard finishes comply with RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation of Chemicals) regulations. We no longer use hexavalent chromium passivations except where specifically required by legacy aerospace/defence approvals.

Q: How do I prevent galling with stainless steel fasteners?

A: Galling (cold welding) is common with stainless steel-on-stainless assemblies. Solutions include: dry-film lubricants (PTFE/Xylan), silver plating, copper-based anti-seize, wax coatings, or using dissimilar materials (e.g., stainless bolt with bronze nut). Reduce installation torque and use controlled tightening procedures.
