Products information 1) Material: 40Cr or 42CrMo 2) Surface: black oxygen, galvanization or as your request 3) Hardness: 36~42HRC 4) Grade: 10.9, 12.9 5) Impact Strength: ≥12~15J (at 25°C) 6) Package: boxes packed in Plywood Cases 7) Application :used in a wide variety of applications across all Caterpillar machinery,they are used to secure the track plates to the undercarriage frame of heavy machinery like excavators, bulldozers, and tracked loaders.
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.

Surface finish options include black oxide, zinc plating and Dacromet coating which can enhance rust and corrosion protection. Our Caterpillar track bolts are suitable for harsh working conditions including earthmoving, mining, quarrying and infrastructure construction.
