Self drilling screws, also known as Tek screws, are fasteners with a special pointed end style that allows them to penetrate thin materials without a starting or pilot hole. 
Also known as self tapping screws or self drilling bolts, they cut or form threads to engage with the mating material.
Our range of self drilling screws, are specially designed and tested for drilling steel sheets of thickness upto 6mm, without breaking or bending.

A screw is a small metal rod with a notch in the top that's used as a fastener. You can attach one piece of wood to another by rotating a screw through the two surfaces. A screw is similar to a nail, but instead of hammering it in, you turn it repeatedly with a screwdriver.
