This M10 x 40mm fully threaded hex bolt is manufactured to DIN 933 in A2 stainless steel (304 grade). DIN 933 specifies a hex head bolt with thread running the full length of the shank, making it suitable for nuts, threaded inserts, and through-bolted joints. 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 full metric coarse thread runs the complete length of the shank, engaging all available thread in shallow tapped holes and maximising pull-out resistance.

Typical applications

  • Light structural assemblies and general fabrication in non-coastal environments
  • Joinery, cabinetry fixings, and furniture frames
  • Mechanical brackets, shelving systems, and guard rails
  • General indoor and outdoor fastening where A2 corrosion resistance is sufficient

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.
