M8 X 55 Hex Non-Serrated Flange Screw 10 Pack DIN 6921 A2 Stainless Steel
- RRP
- £6.52
This M8 x 55mm hex flange screw is manufactured to DIN 6921 in A2 stainless steel (304 grade). DIN 6921 specifies a hex head screw with an integral flange beneath the head, spreading the clamping load without a separate washer. Property class A2-70 indicates a minimum tensile strength of 700 MPa - stronger than standard A2-50 and suited to structural fixings where higher clamping force is needed. The integral flange spreads clamping force over a wider bearing area than the head alone, protecting the surface and removing the need for a separate washer during assembly.
Typical applications
- Assembly work where a separate washer slows fitting
- Fixings into softer sheet, plastics, or castings
- Vehicle, trailer, and machinery assemblies
- Guards, brackets, and general fabrication
Available in packs of 10 to 50, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns. For coastal, marine, or chloride-rich environments, Simfix A4 (316 grade) equivalents are available.
