Description

The F272 die nuts from Dormer have G-series (British Standard Pipe) thread forms and are designed to re-cut original external threads which have been damaged. They have a bright finish which gives clean, accurate threads by preventing workpiece material from sticking to the cutting edges, and are made from High Speed steel for improved performance and longer tool life. They will create accurate screw threads to class A tolerance when used with the appropriate spanner to repair threads by hand.
