产品说明

DIN 931 Zinc Plated Carbon Steel Hex Head Bolts are partially threaded metric fasteners designed for machinery assembly, steel structure connection, equipment installation, construction hardware, and general industrial fastening.

This product features a hex head, carbon steel body, zinc plated surface, 和 partially threaded shank. Compared with fully threaded bolts, the DIN 931 partial thread design includes a smooth shank section, which helps improve positioning and provides stable support in assembled parts.

For buyers, this product solves a common procurement problem: choosing the correct bolt type when the application requires a smooth shank plus threaded end, not a fully threaded DIN 933 bolt.

What Procurement Problems Does This Bolt Solve?

Purchasing Problem	该产品有何帮助
Wrong standard selection	DIN 931 is clearly used for partially threaded hex bolts.
Confusion with DIN 933	DIN 931 has a smooth shank section, while DIN 933 is fully threaded.
Need for stable positioning	The smooth shank helps keep parts aligned during assembly.
Need for surface protection	Zinc plating helps protect the carbon steel surface from oxidation.
工具兼容性	Hex head design works with standard wrenches, sockets, and torque tools.
装配配套	Can be paired with matching metric nuts and washers.

DIN 931 vs DIN 933

标准型	螺纹类型	主要区别
DIN 931	部分螺纹	Has a smooth shank and threaded end
DIN 933	全螺纹	Thread runs along the full bolt body

该产品是 DIN 931, because it has a clear smooth shank section between the hex head and the threaded part.

材料和表面处理

The bolt is made from 碳钢, which is widely used in industrial fasteners for practical strength and cost-effective performance.

的 zinc plated finish gives the bolt a silver metallic appearance and provides surface protection for general industrial use.
