What we make
Fasteners that cannot be bought from a catalogue
Our non-standard fasteners go where a stocked part will not do: an odd length or head, a superalloy or duplex grade, an uncommon thread, or a standard part that must be made from traceable UK, EU or US material. Everything is made in our own facility in Willenhall, West Midlands.
We have made special fasteners since 1971, for OEMs, contractors and fastener distributors in the UK and worldwide. Choose a product family below, or send us your drawing and we will tell you how we would make it.

Questions
Frequently asked questions
Do you make non-standard fasteners to drawing?
Yes. Most of what we make is to customer and OEM drawings. Send the drawing with quantity, material and documentation requirements and we will quote.
What is the minimum order quantity?
There is no minimum. We make single prototypes and breakdown replacements as well as batches of several hundred.
Can you make a standard fastener in a special material?
Yes. Catalogue sizes in superalloys, duplex and other grades nobody stocks are a large part of our work.
Where are your fasteners made?
In our own manufacturing centre in Willenhall, West Midlands, from UK, EU or US mill material only.
Can you copy a part from a sample?
Yes. Send a photograph beside a rule for a quick estimate, then the sample, and we can arrange collection for large items. We can replicate it, with an upgraded material, length or thread form if needed.
