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

Because bolts are also a kind of railway accessories, railway accessories are an integral part of railway lines. The track referred to here includes steel rails, sleepers, connecting parts, track beds, anti climbing equipment, rail braces and turnouts.

As an integral engineering structure, the track is laid on the subgrade, which plays a guiding role in train operation and directly bears the huge pressure of rolling stock and its load. Under the dynamic action of train operation, each component of the train shall have sufficient strength and stability to ensure safe, stable and uninterrupted operation of the train at the specified speed.
