Hex Head High Thread Fine Thread – c/w Bonded Washer

This screw is designed for the secure fastening of composite panels and cladding sheets through insulation. It features a high under-head thread to prevent compression of the outer sheet and to deliver maximum support across the panel surface. The inclusion of a bonded washer ensures a tight, weatherproof seal, making it ideal for external applications where sealing and durability are critical.
