Basic Introduction Of Bolts

Bolts: mechanical parts, cylindrical threaded fasteners with nuts. A type of fastener consisting of a head and a screw (cylinder with external thread) needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Bolt: a type of fastener consisting of a head and a screw (a cylinder with an external thread), which needs to cooperate with a nut to fasten and connect two parts with through holes.

Because bolts are also a type of railroad fittings, railroad fittings are an integral part of railway lines. The track here refers to steel rails, sleepers, connecting parts, track beds, anti-climbing equipment, rail braces and turnouts.

As an integrated engineering structure, the track is laid on the subgrade, which plays the guiding role of the train operation and directly bears the huge pressure of the rolling stock and its load. Under the power of train operation, its various components must have sufficient strength and stability to ensure that the train operates safely, smoothly and uninterruptedly at the maximum speed specified.
