Description

F312 die nuts for metric fine threads will create accurate screw threads to 6g tolerance. The bright finish stops work piece material from sticking to the cutting edges for a further guarantee of accuracy and clean threads. F312 die nuts are manufactured from High Speed steel for longer tool life and improved performance and are designed to repair any damaged external metric threads by re-cutting the original thread form. They should be used by hand and held in the appropriately sized spanner, when accurate screw threads with a 6g tolerance will be achieved.
