railway track bolts, fish bolts 24x145mm,45# Grade 8.8 with black
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
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.
