M3 x 12mm Hex Set Screw | DIN 933 | A4 Stainless Steel

The M3 x 12mm size gives this Hex Set Screw a useful fixing profile for plant room installations, with a hex head that can be tightened using conventional workshop tooling.

The A4 stainless steel construction suits exposed fittings, marine hardware and installations where long-term corrosion resistance is required. 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

  • Repair teams replacing worn fixings on machinery and production assets
  • Machinery guarding, motor mounts and equipment service panels
  • Inspection benches, test rigs and adjustable jig construction
  • Automation cell guarding, robot perimeter frames and production safety panels

Why Choose This Fully Threaded Hex Screw?

  • 0.5mm pitch provides predictable thread compatibility across standard metric components
  • 2.1mm head height helps with clearance planning during equipment design
  • A4 stainless steel hex set screw wording gives this SKU a clear use case within the broader DIN 933 set screw range
