Hex Head Bolts DIN 931 (ISO 4014) M12 in Duplex Stainless Steel 1.4462 / 316LN

The most common type of fastener, a hex head bolt is designed to be tightened with a standard spanner or ratchet and socket. Popularly used in all assemblies, a standard hex bolt is a staple across the world. Manufactured to ISO 4014 or DIN 931, and therefore includes an unthreaded section of the shaft. A hex drive permits a greater torque load to be applied to the joint over most other drive types.
