This 4.8mm x 38mm Pozidriv pan head self-tapping screw is manufactured to DIN 7981-C in A4 stainless steel (316 marine grade). DIN 7981-C specifies a Type-C thread form with a sharp, thread-cutting tip that forms its own mating thread into the parent material on first drive. This eliminates pre-tapping in light sheet metal, UPVC, and similar thin-gauge materials. The pan head sits above the surface, providing a visible clamping face - practical for sheet metal work, cladding panels, and electrical enclosures where a flush finish is not required.

Typical applications

  • Marine and coastal installations with saltwater and chloride exposure
  • Swimming pool surrounds, water treatment plant, and pump assemblies
  • Offshore and waterside structures with prolonged wet exposure
  • Chemical plant, food processing, and washdown environments

Available in packs of 25 to 200, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns.
