M20 x 140mm Hex Head Bolt DIN 931 | A4-80 Stainless Steel
Use this M20 x 140mm part threaded hex bolt when heavy engineering assemblies needs a strong metric fastening that can be tightened from the head side. The DIN 931 form offers a standardised shank and thread layout for predictable installation. This makes the metric hex head bolt useful when a standard metric fastening has to match existing drawings.
DIN 931 sizing improves interchangeability across maintenance stores, OEM builds and fabrication projects where consistent metric hardware is needed. The 12.9mm head height gives the installer a clear external drive for workshop and site fitting.
