3.5mm x 8mm Pozi Flange AB Self Tapping Screw BS 4174 | Black Zinc Steel

The 3.5mm x 8mm format makes this screw useful for fastening covers, guards and light brackets without relying on a separate washer in many cases.

With BS 4174 sizing and the AB end type, this screw is suitable for consistent replacement where an existing flanged self tapping fixing is specified. The AB end type should be used with a suitable pilot hole for the material being fastened.

Common Applications

  • Machine guard fastening
  • Furniture hardware mounting
  • Agricultural machinery guards
  • Black zinc visible fixing for food processing equipment covers
