Bolts – hardware elements used for flexible connections in machine parts
Bolts are hardware elements used for the assembly of one or more machine parts into a flexible connection. A bolt may have two mechanical parts that oscillate or one part is fixedly connected to the bolt. The oscillating part is connected with a loose fit and the fixed part is connected with a close fit. In fitted connections the bearing bush is inserted into the oscillating part, a machine element of a hollow cylinder, which is designed to adapt to two cylindrical elements. The moving part of the bolt must be lubricated, as it is exposed to wear.
There are different types of bolts - without a head, with a head, and with a head and a screw plug. The above mentioned bolts have a head, which is formed in a way to be easily held with the bolt key and are secured by a nut and washer against axial displacement. Smooth bolts and bolts with a small or big head may have a hole for the cotter pin, which is a securing element against failure of the bolt or nut loosening. This is why we must always use a washer. Smooth bolts without heads can also be tubular and are protected by a snap ring against axial displacement.

Bolts – variety of uses
