DIN 960 specifies partially threaded metric hex bolts with fine thread pitch used in machinery, equipment and industrial fastening applications. Unlike DIN 931, which uses standard coarse thread, DIN 960 fasteners use a finer pitch thread while maintaining a partially threaded shank for improved alignment and shear strength.

DIN 960 bolts are widely used in maintenance, repair and assembly operations where reliable fastening, controlled load distribution and improved resistance to loosening are required.

DIN 960 defines:

• Partially threaded metric hex bolts

• Fine thread pitch by diameter

• Hex head dimensions

• Mechanical strength requirements

• Manufacturing tolerances

​​

These bolts feature a partially threaded shank with fine pitch thread that improves load distribution and provides better resistance to vibration and loosening in mechanical assemblies.
