DIN 931 Hex Bolts: Partially Threaded Strong Fasteners for Versatile Use

DIN 931 Standard – High-Quality Partially Threaded Bolts

DIN 931 hex bolts feature partial threading, providing greater shear strength in the unthreaded shank area, making them ideal for structural and mechanical applications.

DIN 931 8.8 Material – Medium Carbon Steel with High Strength

Bolts produced under the DIN 931 8.8 grade are made from quenched and tempered medium carbon steel, offering excellent tensile strength and durability for demanding environments.

DIN 931 M10 – Common Size for Industrial Applications

The M10 size is a popular diameter for DIN 931 bolts, balancing strength and versatility for use in machinery, automotive, and construction projects.

Comparison Between DIN 933 and DIN 931 Hex Bolts

While DIN 933 bolts are fully threaded, DIN 931 bolts have partial threading, allowing for stronger shear resistance and better load distribution in applications requiring secure and durable fastening.
