M39 x 120mm Hex Head Bolt DIN 931 | A2 Stainless Steel

Designed for electrical enclosure builds, this M39 x 120mm DIN 931 hex bolt combines a plain shank section with a threaded end for strong alignment through prepared holes. The A2 Stainless Steel specification makes it suitable for general stainless assemblies, equipment frames and clean finish applications. This makes the M39 x 120mm hex head bolt useful when a standard metric fastening has to match existing drawings. This option gives buyers a clear M39 bolt choice for assemblies where a plain shank section is preferred under load.

DIN 931 sizing improves interchangeability across maintenance stores, OEM builds and fabrication projects where consistent metric hardware is needed. The 84mm threaded section gives enough engagement for matched hardware while the 120mm overall length supports through-bolting and spaced components.

Common Applications

  • Clamping cabinet frames in electrical enclosure builds
  • Fastening backplate supports using M39 metric hardware
  • Installing control panel brackets where A2 Stainless Steel is specified
  • Joining door hardware mounts requiring DIN 931 part threaded bolts
