Our aftermarket Caterpillar track bolts are high-strength fasteners for undercarriage systems, they are always paired with track nuts to secure track shoes onto track links,and widely used on Caterpillar excavators, dozers and wheel loaders. The track system endures heavy impact loads, alternating shear force, abrasive wear and mud-water corrosion during operation. Therefore, track bolts require outstanding tensile strength, shear resistance and fatigue life.
Our aftermarket Caterpillar track bolts are manufactured to match OEM part numbers. Dimensions, thread profile and head geometry are fully compatible for direct replacement. Except standard track bolt, we also supply high head track bolt ,short shank track bolt and flange track bolt. All of them are made of premium alloy steel with precision heat treatment for stable mechanical performance. Threads are roll-formed to avoid cutting marks at thread root, delivering superior fatigue resistance and reducing thread breakage risk.
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
Welcome to contact us for more detailed Caterpillar track bolts information : we promise that every batch undergoes hardness testing, tensile strength, yield strength and metallurgical tests. Depend on stable quality, reasonable price and reliable lead time , we win more and more global customers's recognize and long-term orders !
