About British Standard Fine
British Standard Fine is the fine pitch companion of British Standard Whitworth (BSW), and is a screw thread that was commonly used on bolts and nuts for British machinery and vehicles from 1908 until the widespread adoption of Unified and Metric threadforms in the late 1940s.
More recently, this threadform has seen widespread usage in vintage vehicle and heritage rail restoration projects.
We carry a huge range of BSF bolts and nuts in stock and can manufacture specials onsite to your exact requirements.
