High-Strength Bolts For Rail Track | Fish Bolt, Clip Bolt, Special Bolt Material 50#
Track bolts are generally hexagon domed head bolts. They are used to secure the track plates to the track chains on crawler equipment such as bulldozers. Zhongyue track bolts are forged from alloy steels and heat-treated to the specifications of the original equipment manufacturers.
We also produce many double head screws each year according to clients' drawings or samples.
Track bolts are made in either inch-series with UNRF or UNRS threads, or metric with fine-pitch threads. They are secured by either square, hexagon or special domed track nuts.

Strength grade

From the strength grade of steel, high strength bolt with 8.8s and 10.9s strength grade, most are 10.9s. By contrast, common rail bolt with lower strength grade like 4.4s, 4.8s, 5.6s and 8.8s.

Loading feature

High strength bolt exert pretension force to screw and produce extrusion force between connecting components. So that creating great friction perpendicular to the direction of screw. Besides, pretension force, anti-sliding coefficient and steel types have great influence on bearing capacity of high strength bolt. Common railroad bolt transmit shear by shear resisting of screw and bearing stresses along bolt hole.


High strength bolt can be applied in the main member. Generally, high strength bolt is permanent connection, in other words, single use only. High strength bolt is the pre-stressed bolt. Frictional type was added pre-stress by torque wrench. Bearing type shakes off the plum flower head. Common railway bolt is reusable and it has poor shear resisting, so it is mostly applied in the secondary member.
