Product Description
DIN 7968 - Hexagon fit bolts with hexagon nut for steel structures
Leader-Fastener® DIN 7968 Hex Bolt is a type of fastener consisting of a head and a screw (a cylinder with an external thread). It needs to be matched with a nut to fasten and connect two parts with through holes. Because bolts are also a kind of railway accessories, railway accessories are an integral part of railway lines. The tracks referred to here include steel rails, sleepers, connecting parts, ballast beds, anti-climbing equipment, rail braces and turnouts.
As an integral engineering structure, the track is laid on the roadbed, which plays a guiding role in the operation of the train, 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 runs safely, smoothly and uninterruptedly according to the specified maximum speed.
