Description
These are super long shank .
New old stock 5/16″ – 22 British Standard Fine BSF
Useful for high speed steel applications like custom boring bars, D bits, making cutting tools.
These are brand new taps never been used and often in original packaging. Mostly Made in the USA. I have hardness tested some of the shanks and the wrench ends are between 50-55 HRC and the tap ends are 60-64 HRC if knowing this is useful. They may not all be the same.
