5.5mm x 32mm hex head self-drilling screw in A2 stainless steel to DIN 7504-K. The drill-point tip bores and taps into light-gauge steel in a single operation - no pre-drilling or tapping required for thin sheet and steel cladding. A2 (304 grade) gives good corrosion resistance for indoor and non-coastal outdoor use. Free next-day UK delivery on orders over £50.

This 5.5mm x 32mm hex head self-drilling screw is manufactured to DIN 7504-K in A2 stainless steel (304 grade). DIN 7504-K specifies a self-drilling, self-tapping screw: the drill-point tip bores through light-gauge steel sheet and simultaneously taps a thread in a single driving operation, eliminating the separate pre-drilling and pre-tapping steps required with standard screws. This significantly reduces installation time in steel cladding, roofline purlins, and light structural steelwork. The hex washer head sits above the surface with a built-in seating face, suited to standard sockets, magnetic nut-runners, and impact drivers for high-speed power-tool installation. The drill point is rated for specific material thicknesses - use the correct screw length for the combined substrate thickness.

Typical applications

  • Light-gauge steel cladding, purlins, and roofline fixings
  • Metal-framed partitioning, mezzanine floors, and steelwork connections
  • Sheet metal enclosures and fabrication where pre-drilling is not practical
  • Indoor and sheltered outdoor structural metalwork

Available in packs of 50 to 250, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns.
