Intafast stock and supply a range of thread forming screws also known as Taptite® Tap-fix® screws. They are available in both inch and metric sizes with head styles to suit, in various materials and finishes.
Thread rolling screws are designed to tap their own threads when driven into a pre-drilled hole without the need for thread tapping.
The triobular thread shape of the screw is designed to aid thread cutting and ease the radial force during installation.
