Dormer F302 Hss Dienuts Metric Coarse Thread 16.0 X 2.00 Pitch

F302 die nuts for metric coarse threads are manufactured from High Speed steel for superior performance and extended tool life and come in a range of sizes from M3 to M36. They have a bright finish which prevents workpiece material from sticking to the cutting edges of the tool and means you get a cleaner, more accurate thread. F302 die nuts are designed to repair damaged external threads by re-cutting the original thread form. They should be held with the appropriate imperial size spanner and used by hand where they will create accurate screw threads to 6g tolerance.
