M12 x 300mm Hex Head Bolt DIN 931 | A4-80 Stainless Steel
This M12 x 300mm hex head bolt is a part threaded DIN 931 fastener for HVAC support work. Its A4-80 stainless steel construction supports secure clamping where a spanner-tightened hexagon head is preferred over a socket drive. It is a practical option for buyers searching for a M12 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 49mm threaded section gives enough engagement for matched hardware while the 300mm overall length supports deep sections, packers and large fabricated joints.
Common Applications
- Securing duct brackets in HVAC support work
- Mounting fan frames using M12 metric hardware
- Assembling roof plant supports where A4-80 Stainless Steel is specified
- Supporting serviceable equipment fixings requiring DIN 931 part threaded bolts
