M5.5*38 Stainless Steel 410 Hex Head Self Drilling Screws
Meet the reliable M5.5*38 Stainless Steel 410 Hex Head Self Drilling Screws.
Designed for efficiency, these screws combine a hex head for enhanced torque control with self-drilling capabilities that eliminate pre-drilling steps.
Made from 410 stainless steel, they resist rust and maintain structural strength over time. The countersunk hex head provides flush finishes for clean installations. Each screw is burr-free for smooth operation.
Customize with client-specified gaskets (PVC/EPDM) for specialized applications. Surface treatments include long-lasting galvanizing, Dacromet, or colored coatings.
We offer tailored packaging solutions and material alternatives (carbon steel) to meet project requirements. Perfect for heavy-duty fastening in buildings, fences, or equipment.
