M12 x 20mm Hex Set Screw | DIN 933 | A4-70 Stainless Steel

Manufactured to DIN 933, this M12 x 20mm Hex Set Screw is designed for assemblies that need full thread engagement through the joint.

The A4-70 stainless steel grade is selected for outdoor, marine and washdown environments where resistance to corrosion is a key requirement. The hex head design gives better tool contact than a low profile drive when installers need reliable torque transfer during maintenance or assembly.

Common Applications

  • External plant, chemical handling areas and marine-grade maintenance work
  • Automotive fixtures, trailer repairs and plant equipment brackets
  • Lightweight panel work, plastic assemblies and non-metallic fixings
  • Temporary fixtures, prototypes and adjustable mechanical test builds

Why Choose This Fully Threaded Hex Screw?

  • DIN 933 specification gives a clear standard for replacement and repeat ordering
  • A4-70 Stainless Steel construction supports the intended environment and fastening load
  • External hex drive gives practical access where internal drive screws may clog or round off
