M12 x 100mm Hex Head Bolt DIN 931 | A4-70 Stainless Steel

When a bolted joint needs both shear support and threaded engagement, this M12 x 100mm hex head bolt provides a dependable DIN 931 option for signage and gantry work. Its 30mm threaded length gives a measured engagement zone for compatible nuts or tapped parts. It is a practical option for buyers searching for a A4-70 Stainless Steel hex bolt with measured DIN 931 geometry.

The partially threaded design is useful where the shank passes through one component and the threaded end clamps against the mating part, helping reduce movement in bracketed assemblies. The 30mm threaded section gives enough engagement for matched hardware while the 100mm overall length supports through-bolting and spaced components.

Common Applications

  • Aligning mounting rails in signage and gantry work
  • Replacing gantry plates using M12 metric hardware
  • Fixing support frames where A4-70 Stainless Steel is specified
  • Upgrading inspection panels requiring DIN 931 part threaded bolts
