A fit bolt looks like an ordinary bolt but has significant differences. The head is hexagonal, and the shank has a long metric thread of standardized pitch. Between the shank and the head there is a section of smooth surface of a certain length. It is made of steel with a property class of not less than 8.8. Depending on the operating conditions, the bolt may have an anti-corrosion coating or none. According to the DIN standard, cross-section dimensions range from M8 to M30, and length ranges from 25 to 200 millimeters.

The DIN 7968 bolt is used to firmly join various structural elements or entire systems. It is used with washers, nuts and spring washers of the corresponding size. The bolt works to clamp and draw together structural assemblies. When used with cup washers, it functions like a rivet, which prevents premature failure of the joined parts and surfaces under extreme loads.
