Earthmoving machine replacement parts don’t get more fundamental than the bolts holding track shoes to chain links. These fasteners keep ground-engaging components in place under continuous impact and tension loading. This aftermarket track bolt & nut m20*57 (M20×57mm) is manufactured to OEM grade and dimensional specifications for reliable field performance.

Compatible Machines

Heavy-Duty Construction
This track bolt & nut m20*57 is manufactured using thread form machined to class tolerances. Anti-corrosion coating for resistance to mud, water ingress, and abrasive debris. Surface finish prevents galling on installation and removal. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.

Applications
Suitable for a wide range of heavy equipment and undercarriage systems including:
– Excavators
– Dozers
– Loaders
– Track roller assemblies
– Earthmoving machinery undercarriage components

Maintenance Recommendations
– Use calibrated torque wrench — never impact-gun final torque on track bolts
– Replace as a set; mixed-age bolt/nut combinations can fail early
– Recheck torque at first service after shoe installation
