When it comes to heavy construction machinery, every component matters. One small part can decide whether your excavator keeps moving smoothly or ends up stuck in downtime. Among those crucial undercarriage components, CHZ M22-65 Track Bolts play an essential role in keeping your track shoes tightly secured, ensuring maximum performance and durability in every operation.

What Are M22-65 Track Bolts and Why They Matter

Track bolts are the connectors that hold the track shoes onto the link assembly of an excavator or bulldozer. The model M22-65 refers to its specifications: a 22mm diameter bolt with a 65mm length. While this might sound like a small part, in reality, it bears incredible force, vibration, and pressure during heavy-duty work.

Poor-quality bolts can easily loosen or break, which can cause severe undercarriage damage. That’s why CHZ M22-65 Track Bolts are designed with high precision, superior materials, and a strong surface treatment to withstand harsh working conditions. These bolts ensure that your machinery maintains stability and traction even under extreme environments like mining, construction, or quarry work.

CHZ M22-65 Track Bolts Engineered for Durability

CHZ manufactures M22-65 track bolts using premium alloy steel such as 40Cr and SCM435, which guarantees excellent hardness, tensile strength, and fatigue resistance. Each bolt undergoes advanced heat treatment, CNC precision machining, and quality inspection to ensure consistency and performance.

Key Features:

• High Tensile Strength: Designed to handle vibration, shock, and torque without loosening.

• Perfect Thread Fit: Accurate thread rolling ensures stable fastening and smooth installation.

• Corrosion Resistance: Surface treated with black oxide or phosphate coating to resist rust.

• OEM Compatibility: Suitable for popular excavator brands including Komatsu, Caterpillar, Hitachi, and Doosan.
