This M4 x 20mm Pozidriv countersunk machine screw is manufactured to DIN 965 in A2 stainless steel (304 grade). The flat-flush countersunk head sits level with or below the parent material surface when driven into a correctly counterbored hole, leaving a clean finish with no protruding head or sharp edge. DIN 965 specifies a 90-degree countersunk angle, compatible with standard 90-degree countersinks and spot-face tooling. Suitable for use in pre-tapped holes or through-bolted with a matching M4 hex nut.

Typical applications

  • Light engineering assemblies and fabrication brackets requiring a flush head
  • Electrical enclosures, panels, and cabinet work
  • Signage fixings where a flush surface finish is required
  • Furniture fittings, hinge plates, and joinery hardware

Available in packs of 10 to 100, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns.
