This M5 x 40mm socket cap screw is manufactured to ISO 4762 in A2 stainless steel (304 grade). ISO 4762 specifies a cylindrical head with an internal hex socket, driven with a hex key (Allen key). The tall cylindrical head allows deep socket engagement and transfers high torque without the need for a spanner clearance envelope - allowing use in recessed positions and confined assemblies where a standard hex head bolt would be inaccessible. The compact head profile suits applications where appearance and precision are both important.

Typical applications

  • Machinery, workshop jigs, and precision engineering assemblies
  • Electronics enclosures, panel mounting, and instrument fabrication
  • Furniture fittings, cabinetry, and architectural metalwork
  • General indoor and workshop fastening where a low-profile hex head is preferred

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