Timco Self Drilling Screws (TEK Screws)
Self-drilling screws, also known as Tek screws. Eliminate the need for a pre-drilled hole which allows drilling and fastening to be done in the same motion. Tek screws may look like standard screw, compared to the more unique thumb screw, but they include small carving piece at the end of the screw. This helps create a place to start for when you are drilling the tek screw.
