This M6 x 8mm socket button head screw is manufactured to ISO 7380-1 in A2 stainless steel (304 grade). ISO 7380-1 specifies a low domed head driven by an internal hexagon socket, giving a rounded, finished appearance with a low profile. The shallow domed head presents a smooth surface with no sharp edge, covering a wider bearing area than a cap screw while standing well clear of moving parts.

Typical applications

  • Visible fixings where appearance and a smooth finish matter
  • Guards and covers where a low, rounded head reduces snag risk
  • Furniture, displays, and shopfitting
  • Light assembly where a cap screw head would look heavy
