Our hex head self-drilling screws with integrated PVC washers deliver an all-in-one solution for drilling, tapping, and fastening. Specifically designed for metal roofing, steel structures, and industrial cladding, these fasteners combine high-torque installation with reliable, cost-effective weatherproofing.
Hex-head design supports higher torque and reduces cam-out during power tool fastening.
PVC washer provides a watertight seal at the fastening point.
Self-drilling tip enables direct fastening into steel without pre-drilling, combining drilling and fixing in one step.
