British Fastener Specs


Ordering British sized fasteners, taps, dies and tools can be confusing. That's why metric was invented. But, we know our stuff, and we're here to help you. Did you know that many people ask us for Whitworth fasteners, but in fact need British Cycle, or British Standard Fine. Not all British threads are Whitworth.

We've put together a large range of help documents and diagrams to assist you. Feel free to browse them below, but don't feel bad if you need to pick up your computer, tablet or phone and reach out to us.
