When it comes to maintaining excavators, bulldozers, and other heavy construction equipment, every bolt counts — especially those securing the track shoes. Among the most commonly used sizes is the M22-65 track bolt, designed to fasten track shoes to the track links with maximum stability. If you're looking for a strong, durable, and factory-priced solution, the CHZ M22-65 Track Bolts are exactly what your project needs.

Let’s dive deeper into what makes these bolts a top choice for global equipment owners and suppliers.

What Is an M22-65 Track Bolt?

The “M22-65” designation refers to a metric bolt that is 22mm in diameter and 65mm in length — a standard size used across a wide range of excavators and bulldozers, especially in Komatsu, Caterpillar, Hitachi, and Doosan models.

These bolts are typically used to:

• Fasten track shoes to the chains

• Maintain alignment under high stress

• Prevent loosening due to vibration

• Support consistent track movement

Now, that might sound basic — but without the right track bolt, your whole undercarriage’s at risk.

Signs You Need to Replace Track Bolts

Using worn-out or low-quality bolts can lead to serious issues like track detachment, undercarriage damage, or even job-site accidents. Here's what to watch for:

• Rust or pitting on the bolt surface

• Threads stripped or hard to tighten

• Bolts loosening during machine operation

• Rounded heads or deformed shanks

• Cracking sounds while the machine is moving

We’ve all been there — thinking “it’ll hold” and then... boom. Machine downtime.

(intentional grammar error: “then... boom” used as a sentence fragment)
