M30 x 120mm Hex Head Bolt DIN 931 | A4-70 Stainless Steel

This M30 x 120mm hex head screw style bolt is made for automotive manufacturing lines, giving a clean externally driven fixing for metal sections, brackets and equipment frames. Its A4-70 Stainless Steel material choice is well suited to external, wash-down and coastal applications where A4 stainless steel is preferred. It is a practical option for buyers searching for a part threaded hexagon 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 66mm threaded section gives enough engagement for matched hardware while the 120mm overall length supports through-bolting and spaced components.

Common Applications

  • Fastening fixture plates in automotive manufacturing lines
  • Installing conveyor fixtures using M30 metric hardware
  • Joining assembly cell frames where A4-70 Stainless Steel is specified
  • Building guard brackets requiring DIN 931 part threaded bolts
