Galvanized Hex Head Heavy Duty Self Drilling Screws for Steel

High-quality zinc plating provides a sacrificial barrier against rust and corrosion, significantly extending service life in harsh environments (humidity, rain, industrial atmospheres). Options include standard zinc plating for general use or heavy-duty hot-dip galvanized (HDG) for superior protection in highly corrosive conditions.

Hex washer head (HWH) or hex flange head designed for high-torque driving with impact drivers, wrenches, or sockets. Eliminates cam-out and ensures positive engagement with integrated washer/flange for superior load distribution.

Manufactured from premium heat-treated steel for high hardness and exceptional mechanical properties. Offers superior tensile and shear strength to withstand heavy loads, vibration, and structural stresses.

Sharp, hardened drill point specifically designed to penetrate steel effortlessly. Available in standard drill point sizes (#2, #3, #4, #5) to match steel thickness capacity. Reduces installation time by up to 50% while optimizing chip removal for smoother drilling.
