Applications of Track Bolt & Bolt & Nut
Track Bolt & Bolt & Nut are the backbone of tracked machinery, securing track chain assembly hardware across industries. Here’s where they shine:
Excavator Undercarriage
In excavator undercarriage systems, excavator track bolts fasten links to shoes, maintaining tension and alignment during digging and lifting. Our bolts handle high-vibration environments without loosening.
Bulldozer Undercarriage
For bulldozers, bulldozer track bolt and nut combos endure dozing, ripping, and pushing. They prevent chain derailment on rocky terrain, extending undercarriage life by 20-30%.
Other Tracked Vehicles
- Skid Steers: Compact crawler undercarriage bolts for urban jobsites.
- Crawler Cranes: Industrial fasteners for tracks supporting massive lifts.
- Agricultural Tractors: Reliable track assembly components for field work.
From mining to construction, our heat treated bolts and nuts keep operations moving.
Manufacturing Excellence: How We Produce Superior Track Bolts
XMGT’s state-of-the-art facility in China crafts every Track Bolt & Bolt & Nut with precision engineering.
Surface Treatment
All bolts receive a bluing treatment – a controlled oxidation process that forms a protective oxide layer. This boosts corrosion resistance by 50% compared to untreated steel, ideal for harsh weather.
Thread Standards and Tolerances
- Metric Thread Bolts: M12 to M24, 6g tolerance for tight fits.
- Imperial Sizes: 1/2″ to 1″, 2A tolerance for American equipment.
Threads conform to global specs:
- ANSI (USA)
- DIN (Germany)
- BS (UK)
- AS (Australia)
Material and Heat Treatment
We use high-carbon alloy steel, quenched and tempered for:
- Yield Strength: 1000+ MPa
- Hardness: HRC 32-38
- Elongation: 12% minimum
This makes our high strength bolts and nuts outperform competitors in fatigue tests.
Quality Assurance
Every batch undergoes:
- Ultrasonic testing for internal flaws.
- Torque-tension calibration.
- Salt spray testing (ASTM B117 compliant).
Result? Zero defects and full traceability for your peace of mind.
