What Caterpillar track bolts and nuts are available for excavators and dozers?

Expert Answer

Caterpillar track bolts and nuts are available for many excavator and dozer undercarriages, but the correct fit depends on the machine model, track shoe type, bolt size, and thread pitch. VANROCK supplies track bolts and nuts through its appointed dealer network and can quote on request; exact fitment should always be confirmed from the machine serial number and the existing hardware dimensions.

For Caterpillar undercarriages, the right set is usually chosen by measuring the bolt diameter, thread pitch, under-head length, and nut style, then matching that to the track shoe hole and pad thickness if applicable. A worn bolt can look similar to a correct one, so check for stretched threads, necking, damaged heads, and loose or ovalized shoe holes before reusing any hardware.

If you are replacing bolts and nuts at the same time as track shoes or a track chain service, it is best to keep the hardware matched as a set and inspect the mating surface for wear. VANROCK is an independent manufacturer and is not affiliated with Caterpillar. If you share your machine model and serial number, a dealer can help confirm the exact undercarriage hardware and provide pricing on request.
