FAQ
What is a self drilling (Tek) screw?
A self drilling screw has a drill bit point, so it drills, taps and fastens in one step with no pilot hole. The point number tells you how thick a metal it can drill: the higher the number, the thicker the metal.
How do I install self drilling screws?
Use a screw gun or drill at moderate speed, not full speed, with steady pressure. Let the point finish drilling before the threads engage, and stop when the head seats so you don't strip the threads.
What nut setter do I need?
#6 and #8 take a 1/4 in. nut setter, #10 and #12 take 5/16 in., and #14 takes 3/8 in.
