Description
About this item:
- Unified National Fine (UNF).
- Split circular chrome alloy button dies are most commonly used in conjunction with a die stock handle.
- 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 UNF thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada and the UK.
- The thread profile of UNF is the same as for metric threads and is described in the JIS B0206 standard.
- The thread is described by its major diameter and the number of threads per inch of length (TPI).
- 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 1-1/4 or where wall thickness demands a fine pitch.

Brilliant
The range on offer is complete, the prices are god, and the items were well packed and delivered promptly. All good.
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.
Great service and range of products
The mini hinges are good quality and the service was prompt considering we are in the United Kingdom.
