MACHINED PARTS AND HIGH-VOLUME FASTENERS
LESS WASTE AND MORE RETURN WITH COLD FORGING FASTENERS
Our fastener manufacturing plants specialise in cold forging, which is typically less expensive than hot forging. Cold forging processes are highly reproducible, resulting in:
- High quality fasteners
- Faster production throughput
- Nearly zero material waste
- Minimal machining
- Little to no finishing work

£120,000 Annual Cost Saving
Global commercial garage door manufacturer worked with Optimas to redesign a part that eliminated downtime and yielded cost savings without sacrificing performance.
COLD HEADING
Our specifically-adapted heading machines are designed to compress wire-drawn raw steel between two dies until the final shape of the part is produced.
Station “fingers” transfer each part to the next die between each machine compression. The tooling and dies that compress the material are designed internally and then ordered at the point of receiving a purchase order. If required, they will then be adjusted to achieve the final fastener design.

FAQs
- Wire is uncoiled, straightened and cut to length
- The steel wire is moulded into the correct shape at room temperature using cold forging / forming / heading machines.
- The head of the bolt or screw is progressively formed by forcing the steel into various dies at high pressure.
- The screw or bolt threads are formed by rolling or cutting.
- The fastener is exposed to extreme heat to harden the steel.
- The surface is treated depending on the application.
- The fasteners are quality checked to ensure uniformity and consistency, and then packed for despatch.
Special fasteners are industrial fastening solutions that hold heavy industrial components together under extreme pressure. They are made out of materials that are corrosion-resistant such as stainless steel.
One of Optimas’ fastener manufacturing plants is located in Droitwich in the midlands. Our screws, bolts and nuts can be despatched to you or our staff can replenish your fastener and C-Class component stocks on-site. Learn more.
Manufacturers often place their mark on the head of bolts and screws, and on one end of studs and stud bolts. Our fasteners that are manufactured in the UK are stamped with BCF (Barton Cold Form).
Yes. They are all words used to describe the process carried out to produce a precise combination of high speed and extreme pressure to shape a material into a part.
The biggest advantage of cold forging is its lower cost. Cold-formed parts require less finishing work which results in fewer fabrication steps. Other benefits are less potential for parts contamination during forging, greater control over dimensions, greater ability to handle high stress and high die loads and the ability to produce near-net shape parts.
