Bolt DIN 931 1 1/2x5 1/2 (140 mm) Grade 8 (~10,9) UNC 6

Overview

DIN 931 is a hex head bolt with a partial thread and inch thread. Its design includes a smooth shank section under the head, which helps distribute the load evenly and reduces the risk of stress concentration. The bolt is made from strength class 10.9 material, providing high resistance to mechanical loads.

The inch thread is manufactured according to the UNC standard, making this bolt suitable for applications where inch-sized connections are required. Various bolt sizes are available, allowing the optimal option to be selected for specific needs.

Applications

The DIN 931 10.9 UNC hex head bolt with partial thread is ideal for applications where high strength and reliable connections are required. Strength class 10.9 provides resistance to heavy loads, making it suitable for heavy machinery, construction, and the automotive industry.

Thanks to its inch thread, this bolt is widely used in American and British systems, allowing it to be easily integrated into existing structures. The partial thread provides optimal engagement with the material, increasing resistance to tensile loads.

Alternatives

DIN 931 10.9 UNC is a hex head bolt with a partial inch thread. It is manufactured according to the DIN standard, ensuring high quality and reliability. Strength class 10.9 indicates its ability to withstand significant loads, making it suitable for structures where high strength is required. When selecting alternatives, it is important to consider that this bolt has a UNC inch thread, which differs from metric threading.
