At ITW Shakeproof Industrial, we are your source for TEKS self-drilling fasteners. Our Self-Drilling Fasteners work great in both sheet metals and non-metals. The screw is designed so that the drilling function is completed before the initial thread engages so that all voids and material thicknesses are accounted for.
