This M4 x 16mm button head socket screw is manufactured to ISO 7380-1 in A2 stainless steel (304 grade). ISO 7380-1 specifies a low-profile dome head with an internal hex socket. The wide, shallow head distributes load over a larger bearing area than a standard cap screw of the same thread size, reducing the risk of pull-through in thinner materials. The low profile and smooth dome surface make this the preferred choice for furniture, panel covers, and decorative or visible fixings where a cap screw head would be too prominent.

Typical applications

  • Furniture, cabinetry, and architectural fittings needing a low, wide head
  • Electronics enclosures, panel mounting, and instrument work
  • Workshop machinery guards, covers, and access panels
  • Signage, display systems, and decorative metalwork

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