Hex Nuts
Trojan Special Fasteners Ltd can manufacture all manner of hexagon nuts.Hexagon nuts are industrial fasteners that have at least one threaded hole. Hexagon nuts, also known as hex nuts, are a type of fastener that have six sides and are used to hold two or more parts together. They are typically used in conjunction with a bolt or a screw, and have a threaded hole in the center that allows the bolt or screw to be inserted and tightened.
Hex nuts are used in a variety of applications, including construction, industrial machinery, and household items. They are commonly found in applications such as securing wheels on cars and trucks, attaching parts to machinery, and fastening furniture and other household items.
One of the main reasons hex nuts are used is their ability to be tightened and loosened using a wrench. This makes them easy to use and adjust, and allows for the parts they are holding together to be taken apart or adjusted as needed. Hex nuts are also relatively inexpensive and widely available, making them a popular choice for many applications.
Additionally, hex nuts are designed to be used in conjunction with other hexagonal fasteners such as bolts, screws, and studs, which are also designed to be tightened and loosened using a wrench. This make them easy to find and can be used for variety of application.
The most common shape of a nut is one with 6 sides, because this gives good granularity of angles for a tool to approach from (great in tight spots), a greater number of corners would mean higher angles that are more prone to be rounded off - and we all know the headache of removing a rounded nut or bolt!
What is a single-chamfered nut?
A single chamfered nut is a type of nut that has one end that is angled or beveled and the other is unchamfered and also referred to as the bearing side of the nut. These nuts are also sometimes referred to as full-bearing nuts. The face of one side of the nut is typically angled by 30 degrees. These nuts are not reversible, as in there is only one way to correctly apply the nut to a joint.
The unchamfered or full-bearing side of the nut is the one that is typically applied to the joint. The larger surface area increases friction and should reduce loosening.
Most Whitworth and BSF full nuts are single chamfered, but these are also available as double-chamfered nuts.
What is a double-chamfered nut?
A double chamfered nut is a type of nut has a 30 degree chamfer on both ends of a nut. Most nuts are typically double-chamfered and so they are reversible and either side can be applied to a joint.
What is a washer-faced nut?
A washer faced nut is a type of nut that has a flat surface on one side, similar to a washer. This flat surface is used to distribute the load of a tightening bolt or fastener more evenly across the surface of the material being fastened. This can help to prevent damage or deformation of the material and also help to increase the strength of the joint.
Washer faced nuts are commonly used in applications where a high level of clamping force is required, such as in construction, heavy machinery and transportation. They are also used in situations where the material being fastened is relatively thin or delicate and needs more protection from damage.
It's important to note that washer faced nuts should not be used in situations where a locknut is required, as they do not provide any locking mechanism. They also should not be used in applications that require a high level of precision, as the thickness of the washer face may not be consistent. Finally, they should not be used in corrosive environments as the washer face may not be corrosion resistant.
The hexagon nut has been in mass production since the mid 19th century when machines were capable of mass producing them - it is around this time that the famous Mr Whitworth standardised his screw threads.
We can manufacture heavy hex nuts for a number of our clients. These are larger (have bigger across flats and thicker) than usual nuts of the same size. This increases their overall strength because more threads are engaged and there is a reduction in how much the nut expands because of this increased across flat size. Typical heavy hex nuts utilise the unified thread form, but we do manufacture heavy hex nuts with whitworth and metric threads.
Currently, the two most prevalent thread forms are ISO Metric and the Unified Thread Standard. However, other forms are in existence and Trojan prides itself on manufacturing nuts in almost every thread form available. If it can be cut, we can do it!
In addition to standard preferred sizes, we also manufacture non preferred and non standard or special thread and nut forms and sizes. If you have a drawing, or a sample Trojan Special Fasteners Ltd will make what you want.
We can manufacture from single quantities all the way up to the thousands.
What are lock nuts?
Presently many people refer to locking nuts as 'lock nuts' - although this is not exactly correct.
Lock nuts are nuts, when used in pairs, can provide prevailing torque to 'lock' something in place. In essence, they are thinner nuts (typically 0.45d) and when another nut is tightened against it, as a pair, they provide an amount of prevailing torque to stop the nuts from loosening.
Lock nuts or jam nuts can be used where a low profile nut with a reduced thickness is required.
These nuts are also sometimes referred to as jam nuts or half nuts.
Trojan Special Fasteners will manufacture nuts to standard or even thinner, whatever you require. A drawing is always best for a non-standard fastener but we're well-versed in figuring out your needs from basic dimensional data. These can be machined in various strengths, thicknesses, thread types as well as finishes to choose from.
What are Panel Nuts?
Panel nuts are typically thinner than lock nuts or jam nuts. .
Panel nuts are used to attach small threaded components to, yes you guessed it a panel or enclosure. The type of components which are typically secured to said panels are things like switches, light bulb holders, potentiometers and other electrical components. Typically they have very fine thread pitches. As space is often limited because components are mounted close together and specific torque is not required, they usually have smaller across flats (spanner sizes) than regular nuts of that thread size.
An example of such a panel nut would be:
15/32x32tpi unified panel nut with a 9/16" across flat and 3/32" thickness.
Typically a locking washer is used with the nut to try and reduce the chances of the nut loosening.
