Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
Track shoe bolts and nuts are critical components in excavator undercarriage systems. They fasten the track plates (shoes) to the track chain links, ensuring each segment stays aligned and firmly attached during operation. Failure of these bolts can cause track misalignment or detachment, leading to costly downtime.
These bolts are specially engineered to withstand high vibration, lateral forces, and torsional stress experienced in heavy-duty digging and driving conditions.
Material and Strength Grade
We use premium 40Cr alloy steel for all our track shoe bolts, a material known for its high strength, wear resistance, and excellent mechanical properties after heat treatment.
- Steel Grade: 40Cr
- Strength Grade: Class 12.9 (High tensile)
- Surface Treatment: Black oxide or zinc coating available
- Thread Type: Coarse or fine thread, depending on application
The 12.9-grade bolts offer enhanced fatigue strength, ensuring long service life even under extreme loads.
Manufacturing Process
The production process ensures both structural reliability and dimensional accuracy:
Raw Steel Rods
High-quality 40Cr steel rods are selected and precision cut to length before hot forging.
Hot Forging & Head Shaping
Using red-hot steel billets, the bolt heads are formed through controlled press forging, ensuring structural consistency and mechanical strength.
Pre-Thread Machining
After head shaping, each bolt undergoes pre-machining to prepare for threading, with critical dimension control.
Inspection & Final Packaging
All bolts, nuts, and washers are dimensionally inspected, surface-treated, and packed as kits.
Thread Standards and Customization
Thread Type Options:
- Coarse thread (e.g., M16×2.0) – More resistant to stripping, better for quick assembly.
- Fine thread (e.g., M16×1.5) – Better tension and clamp force, often used in high-precision applications.
We support custom thread lengths, diameters, and hex head sizes to match your excavator model. OEM drawings are welcomed.
Common Sizes
| Bolt Size | Thread Type | Length | Strength Grade | Application |
|---|---|---|---|---|
| M16×60 | Coarse | 60 mm | 12.9 | Mid-size excavators |
| M18×65 | Fine | 65 mm | 12.9 | Large excavators |
| M20×70 | Coarse | 70 mm | 12.9 | Heavy-duty applications |
Other sizes available upon request.
