A Plastite screw forms its own thread in a moulded or drilled hole in plastic. It often takes a low drive torque and resists loosening in vibration. 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 outdoor or wet use. 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.
