Track Bolts

They are used to secure the track plates to the track chains on crawler equipment such as bulldozers.
Ajax track bolts are forged from alloy steels and heat-treated to the specifications of the original equipment manufacturers.

A tensile strength of 170,000 lbf/in2 provides 14% more clamping force that SAE J 429 Grade 8. Impact resistance is greatly improved by tempering and fatigue resistance reduced by having rolled threads and a smooth under-head radius.
Some bolts may be heat-treated to 185,000 lbf/in2 depending upon the requirements of the application.

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.

Split Master Link Bolts are very similar to track bolts and are used to secure the split master link to the track chain in crawler equipment.
