Our aftermarket Caterpillar Split link bolts/Master link bolts are high-strength fastener specially designed for Caterpillar excavator and dozer track split master links. They are always paired with matching nuts, through clamping the two side plates of the track master link to connect and assemble the track chain. The track master link bears the most concentrated load across the whole track chain. During machine travel, it sustains heavy impact, alternating tension and shear force, together with abrasive grit wear and mud-water corrosion. Therefore, split link bolts require much higher fatigue and shear resistance than regular track bolts.
Our aftermarket Caterpillar split link bolts are manufactured to match CAT OEM part numbers. Shank diameter, thread profile, head geometry and mounting dimension are fully compatible for direct replacement.Except Standard hex head split link bolt, we also supply Reinforced thick head split link bolt and Short shank split link bolt. Threads are roll-formed with no cutting marks at thread root, can greatly improve resistance against fatigue fracture.Our split link bolts/Master link bolts are widely used in earth excavation, mining, quarrying, road construction and large infrastructure projects.

To ensure stable quality ,our factory execute strictly quality inspection standard:
1. do raw material spectral analysis to verify steel grade
2. do random hardness test after heat treatment to meet required strength class
3. do tensile and shear load testing to verify ultimate load capacity
4. do thread gauge inspection to ensure smooth assembly with matched track nuts
5. do visual and full dimensional inspection,including shank diameter, length, head thickness and thread tolerance control
