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.

Brilliant

Abbot & Ashby every time if you want quality that works and lasts.
Exactly what I was looking for. A company in the states use an almost identical knife under a different brand name, minor differences, nothing impactful. This has been the knife I have used for work for 10+ years. I keep 2 on hand in case something happens to my daily use one. I will gladly pay the exchange and shipping cost to keep using what works so well for me.
Excellent product Excellent price just needed to wait a little longer for them to arrive, but that's no problem really.
The ordering and delivery process was very straightforward, very happy with the products I ordered. Great service from Beyond Tools, I will use them again.
I have been chasing additional bobbins for years. The original seller did not offer additional spindles.
Beyond tools is able to supply additional spindles. Great
We purchased from beyond tools as we were struggling to locate some brass items in the UK and Europe, we got a great prompt service.

The mini hinges are good quality and the service was prompt considering we are in the United Kingdom.
