M8 x 25mm non-serrated hex flange screw in A2 stainless steel to DIN 6921 at A2-70. The integrated flange washer increases the bearing surface without a separate washer, spreading load evenly across the joint face. A2 (304 grade) gives good corrosion resistance for indoor and non-coastal outdoor use. Free next-day UK delivery on orders over £50.

This M8 x 25mm non-serrated hex flange screw is manufactured to DIN 6921 in A2 stainless steel (304 grade). DIN 6921 specifies a hex head bolt with an integral washer flange below the head. The non-serrated flange distributes the clamping load over a large circular bearing surface without cutting into the parent material - eliminating the need for a separate washer while providing a wider bearing face than a standard hex head bolt of the same size. Property class A2-70 specifies a minimum tensile strength of 700 MPa.

Typical applications

  • Automotive, machinery, and equipment assemblies where a built-in washer face is needed
  • Panel mounting, bracket fixing, and general workshop fabrication
  • Mechanical assemblies requiring increased bearing surface without a separate washer
  • General indoor and sheltered outdoor fixings in non-corrosive environments

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