HSS M3 TO M20 TAP & DIE SET (54PCS)

Tap and die sets are an essential kit to have available if a fastener or fastener hole is threaded and then rendered unusable. By using a tap and die kit, a new thread can be cut, or a damaged thread repaired, especially if it has threaded or has a lot of corrosion on it from years’ worth of build-up. A tap and die set generally consists of the tap and the die. The tap is designed for internal thread cutting, so this would be used on the fastener hole or a nut, whereas a die is used for the external thread, like on a bolt.
