Taptite Screw

A Taptite screw is a thread forming screw for metals and plastics. It forms its own thread in a drilled or cored hole.

A Taptite screw rolls its own thread in a drilled hole rather than cutting it. It often suits metal and plastic parts where a stronger thread is wanted. It is usually driven with a screwdriver or power tool bit that matches its head.

This kind of screw is often made in steel with a corrosion resistant finish. Some are made in stainless steel for corrosive environments. The material affects strength and corrosion resistance.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance for material and dimensions. On receipt, check the thread form and point for damage. Check the drive recess for wear or defects.
