BSF | BRITISH STANDARD FINE DIE NUT
About this item:
- Manufactured from durable chrome alloy, these BSF die nuts offer reliable performance for a variety of threading applications.
- Designed according to British Standard Fine (BSF) specifications, the thread form features a finer pitch than the British Standard Whitworth (BSW), providing more threads per inch for a given diameter.
- Introduced in 1908 and specified under BS84:1956, the BSF thread form delivers greater tensile stress area on external threads compared to coarse threads of the same size.
- Ideal for use as thread chasers to clean existing threads or to create new male threads on non-ferrous metals and plastics.
- Die nuts are especially useful where button dies are unsuitable due to limited workspace or restricted thread accessibility on site.
- Fine threads resist stripping better than coarse threads under high load conditions, making them suitable where external and mating internal threads face equal or greater loads than the screw or bolt capacity.
- These fine pitch threads are also recommended where engagement length is limited or wall thickness demands a finer thread pitch.
- Note that chrome alloy dies are not intended for precision, safety-critical, or high-precision thread creation.
