True Manufacturing Capability – Made in Birmingham

We're manufacturers, not resellers or distributors. All machining takes place in-house at our Birmingham facility, giving us complete control over quality, lead times, and specifications. This means when you order from us, you're dealing directly with the people who make your fasteners.

Our in-house capabilities:

• CNC and conventional automatic lathes for quick machine setup and part turnaround
• Polygon turning equipment (create hexagon or square from round bar)
• Comprehensive tapping capabilities (Metric, Imperial and Unified, all thread forms)
• Cross-drilling and secondary operations
• Thread distortion for prevailing torque features
• Slotting and grooving operations
• In-house inspection and quality verification
• Climate-controlled measurement room

This in-house capability means we can respond quickly to urgent requirements, accommodate design changes, and maintain consistent quality. We're not dependent on third-party suppliers or overseas manufacturers – everything is made in Birmingham.

Quick Turnaround Times Without Compromising Quality

We understand that time is often critical. Our efficient setup and experienced team allow us to offer quick turnaround times without sacrificing quality:

• Same-day quotes on most enquiries
• 3-5 working days typical lead time for standard items in common materials
• 7-10 working days for bespoke items or unusual materials
• Expedited service available for genuine urgencies
• Prototype service – fast turnaround on samples for approval before production

We pride ourselves on keeping our promises. If we quote a lead time, we deliver on it. Many customers come to us specifically because larger suppliers can't accommodate their timescales.

As a specialist manufacturer, we can often be more cost-effective than you might expect – our efficient processes and lack of middlemen mean you're not paying unnecessary markups.
We also understand the importance of excellent customer service, which is why we are dedicated to providing a high level of support and service to every customer, regardless of order size. Whether you're looking for assistance with selecting the right fasteners, need help with the manufacturing process, or have any questions or concerns, our team is always here to help.

No Minimum Order Quantity – Prototypes to Production

Unlike many manufacturers who insist on large minimum order quantities, we're happy to manufacture:

• Single prototypes for design verification
• Small batchesfor trials or limited production

Our efficient setup allows us to be economically viable at single-unit quantities whilst remaining competitive at volume. This flexibility means you can work with one supplier from concept through to mass production.
