M20 x 150mm Hex Head Bolt DIN 931 | A4-80 Stainless Steel
This M20 x 150mm metric hex bolt supports marine and coastal hardware by combining a high-torque hex head with a part threaded shank. The 2.50mm pitch, 30mm across flats and 12.9mm head height give clear installation reference points. The result is a hex head machine bolt that suits precise replacement work as well as new build assemblies.
Use with suitable washers to distribute load and with matching nuts where a through-bolted joint is required. The 52mm threaded section gives enough engagement for matched hardware while the 150mm overall length supports through-bolting and spaced components.
Common Applications
- Assembling dockside equipment in marine and coastal hardware
- Supporting external brackets using M20 metric hardware
- Maintaining stainless assemblies where A4-80 Stainless Steel is specified
- Reinforcing wash-down fixtures requiring DIN 931 part threaded bolts
