DIN 931 hexagon bolts with shank are high-strength metric fasteners designed for structural, engineering, and mechanical fastening applications. Manufactured from property class 8.8 steel, these bolts provide excellent tensile strength and reliable clamping performance where durability and precision are required.

Unlike fully threaded bolts, DIN 931 hex bolts feature a partially threaded shank. This design improves shear strength and alignment when fastening components together, making them ideal for automotive, fabrication, machinery, and motorsport assemblies.

Each bolt is finished with zinc plating and blue passivation (A2K) to provide corrosion resistance suitable for general workshop, industrial, and mechanical environments.

This product page includes multiple metric diameter options, allowing you to select the correct size for your application.

Available sizes include:

• M10 DIN 931 hex bolt with shank

• M12 DIN 931 hex bolt with shank

• M14 DIN 931 hex bolt with shank

• M22 DIN 931 hex bolt with shank

All bolts are manufactured to DIN 931 standards, ensuring consistent dimensions, strength, and compatibility with standard nuts, washers, and engineering assemblies.

Key Features

• DIN 931 standard hexagon bolt with shank

• High tensile steel – property class 8.8

• Partially threaded metric bolt design for improved load distribution

• Zinc plated with blue passivation for corrosion protection

• Hexagon head drive compatible with spanners and sockets

• Available in M10, M12, M14 and M22 metric diameters

Common Applications

DIN 931 hex bolts are commonly used in:

• Automotive and motorsport fabrication

• Engineering and mechanical assemblies

• Structural fastening and machinery builds

• Workshop and industrial equipment

• General fabrication and mechanical repairs

Why Use DIN 931 Hex Bolts?

The partial shank design of DIN 931 bolts allows the unthreaded portion of the bolt to handle shear loads more effectively than fully threaded bolts. This makes them a preferred fastening solution where strength, durability, and precise component alignment are required.
