Overview

Self-Tapping screws tap and form their own threads into the mating material. They are made from medium carbon steel and are case hardened to facilitate tapping into material

Application

Generally used for thin sheet metal but can be used in non-metallic materials

Precision

As Self-Tapping Screws form their own thread, a precision fit is achieved – improved resistance to loosening

Specification

Type AB and type C thread forming screws have 60 deg spaced threads and a gimlet point, for materials that allow plastic
deformation to assist threadforming by displacement without removal of any material

Type B or F thread forming screws have 60 deg spaced threads and a tapered blunt thread. Used in light sheet metal and plastics that
allow plastic deformation to assist threadforming by displacement without removal of any material
