High Wear Resistant Excavator & Bulldozer Undercarriage Replacement Part M22×60 Bolts and Nuts High Strength

The M22×60 Bolts and Nuts are heavy-duty fastening components developed for excavator and bulldozer undercarriage systems. Engineered to secure track shoes, track links, and other structural connections, these fasteners provide reliable clamping performance in applications where equipment is exposed to continuous vibration, high impact, and abrasive operating conditions. Undercarriage fasteners play an essential role in maintaining the stability of crawler equipment. Loose or worn fasteners can accelerate wear on track assemblies and increase maintenance costs.

Our M22×60 bolts and nuts are manufactured to provide accurate fitment, stable preload, and excellent resistance to fatigue, helping maintain the integrity of the undercarriage throughout demanding service conditions. Manufactured from premium alloy steel and processed through precision forging, CNC machining, heat treatment, and strict quality inspection, the M22×60 bolt and nut assembly delivers dependable strength, excellent wear resistance, and long-term operational reliability for both OEM equipment and replacement maintenance.
