Self-Drilling Screws with a hardened drill point that will drill and thread in structural steel and mild steel. These Teks points are designed in a manner much the same as high speed steel drill bits.

To choose the correct fastener, it is necessary to select one where
the length of the drill point is equal to or greater than the total thickness of the material to be drilled including the air-gap. If the drill point is less than the total thickness of the material and the thread engages, then the fastener can break or became impossible to drive.

How To Use
1. Measure the total thickness of the materials to be drilled.
2. Choose a screw that has a drilling capacity equal to or greater than the total thickness of materials to be drilled.
