Industrial Self-Drilling Screws

Self-drilling screws are commonly referred to as TEK® screws after the name-brand fasteners. They are manufactured with specially designed “drill bit” points that eliminate the need for pre-drilling during assembly. These industrial fasteners use their own threads to cut into the mating surface, creating an aggressively secure hold for metal-to-metal or wood-to-metal applications.

Here at BW Industrial Sales, your satisfaction is our number one priority! Our extensive inventory contains a wide range of types, materials, finishes, styles, and size variations to meet your exact self-drilling screw needs. We offer same-day shipping on fastener bulk orders to ensure that you have what you need, precisely when you need it.
