M8 x 25mm Hex Head Bolt DIN 931 | A4-80 Stainless Steel

When a bolted joint needs both shear support and threaded engagement, this M8 x 25mm hex head bolt provides a dependable DIN 931 option for laboratory equipment. Its 22mm threaded length gives a measured engagement zone for compatible nuts or tapped parts. It is a practical option for buyers searching for a A4-80 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. With a 1.25mm pitch and 13mm across flats head, it is easy to specify for brackets, conveyors and production fixtures.

Common Applications

  • Fastening instrument frames in laboratory equipment
  • Installing benching structures using M8 metric hardware
  • Joining protective covers where A4-80 Stainless Steel is specified
  • Building calibration rig brackets requiring DIN 931 part threaded bolts
