Self Tapping Screws


Self Tapping screws are also known as Sheet metal or Thread forming screws.

The thread forming screw forms a mating thread by displacing the material around the pilot hole so that it flows around the screw's threads. Without removing any material it creates a fit with zero clearance.

Available in the following threads and points:

Type AB: spaced threads with a gimlet point for self-starting in thin metal or resin-filled plywood. Recommended for brittle materials

Type A: wider spaced threads with a gimlet point  for self-starting in thin metal or resin-filled plywood.

Type B: spaced threads with a blunt point(with incomplete entering threads) for molded or through holes in thin metal, non-ferrous    castings, plastics or resin-filled plywood.

Type High-Low: twin-lead, consisting of a high and low thread with a blunt point. The lower thread varies in height from 1/3 to 1/2 that of the higher thread, which is sharper and flatter than a standard thread. For use in plastic, nylon, wood or other low density materials . Thread design reduces driving torques, enhacnes resistance to thread stripping, improves pullot strength and lessens risk of cracking the work piece.

 Available head styles:  indented hex washer, pan, modified truss, pancake, flat,oval, button, round and truss.

Available metal and finishes:  zinc plated carbon steel, black phosphate carbon steel,  410 stainless steel, 18-8 stainless steel.
