Hardened Self Drilling Screws in 410 Stainless Steel

Hex Washer Head Self Drilling Screws (also called Self Tapping Screws) are made of hardened 410 Stainless Steel and have a sheet metal thread with a self driller cutting (TEK-5) point to pierce through metals. The hardened Stainless Steel and the TEK 5 point of these screws make them capable of drilling into structural steel. The higher the TEK number the larger the drill point to pierce heavier gauge metals. Hex Head Self Drilling Sheet Metal Screws are installed with a socket or hex nut driver. Hex Washer Head Self Drilling Screws are used in the exterior elements.
