6.3×26mm RoHS Hex Head PVC Washer Trivalent Chromium Zinc Self Drilling SEMS Screws
Designed for heavy-duty metal assembly, this 6.3×26mm Flange-Head Self-Drilling SEMS Screw delivers reliable performance in structural applications.
Constructed from carbon steel, it offers high tensile strength and impact resistance.
The self-drilling point ensures clean, fast penetration into steel up to 2.5mm thick, while the rolled thread minimizes friction during installation.
Corrosion protection is enhanced through zinc plating or Dacromet coating, suitable for exterior exposure. The built-in washer can be selected from PVC or EPDM materials to match sealing needs.
Hex head design supports standard wrenches or sockets, and custom powder coating is available for visual differentiation.
Commonly used in warehouse roofing, metal cladding, and equipment housing, this screw provides a complete, durable fastening solution.
