This Teng Tools tap and die set is ideal for repairing screw threads. Taps cut a thread on the inside surface of a hole, creating a female surface which functions like a nut. Dies, on the other hand, cut a thread on a preformed cylindrical rod, which creates a male threaded piece which functions like a bolt.
This 17-piece set contains 7 metric taps and dies of each dimension, a tap wrench, a die stock and a screw pitch gauge. The tools are supplied in a handy storage tray.
