CRL Self-Drilling Screws combine a drill point and screw into a single, time-saving fastener to reduce labor and installation time. Designed to drill their own hole, form mating threads, and complete the fastening in one operation, each screw is precision machined and heat treated for consistent performance and durability.

These self-drilling screws work well in carbon steel, aluminum, brass, bronze, stainless steel, fiberglass and some thin plastics. The special design eliminates pre-drilling or punch prep and reduces hole-alignment issues. Their unique thread forming lets you fasten dissimilar thicknesses more easily and often with fewer fasteners—ideal for metal roofing, siding, curtain wall and storefront systems, metal window and door frames, HVAC ducts, decking and subfloor assemblies, electrical boxes and conduit, emergency board-ups, and on-site assembly work.

Packaging: sold in resealable tubs of 100 and bulk poly bags of 1000. Long-tail keywords: self-drilling screws for metal roofing, bulk self-drilling screws, self-tapping drill screws for curtain walls.
