Description
About this item:
- 5/16 x 22 BSF Chrome Alloy Die Nut
- British Standard Fine (BSF).
- Die nuts are commonly used when a button die is not suited due to work space restrictions and / or on site thread accessibility.
- They can be used as thread chasers to clean an existing thread.
- They can also be used to create a new male thread on non-ferrous metals and plastics.
- Chrome alloy dies are not suitable for creating precision, safety or critical threads.
- The BSF thread form was based upon the British Standard Whitworth (BSW) but has a finer thread (more threads per inch for a given diameter).
- The thread form was first introduced in 1908 and is specified in BS84:1956.
- When used on external threads this series has greater tensile stress area than coarse threads of the same size.
- Fine series threads will resist stripping out better than coarse threads in areas where the external and mating internal threads are subjected to loads equal to or greater than the capacity of the screw or bolt.
- Fine threads are also used where the length of engagement is limited or where wall thickness demands a fine pitch.
