High Quality Wear Resistant Grade 12.9 6V1792+1s1860 Excavator Undercarriage Parts Track Bolt And Nut

Built for Extreme Duty: Unmatched Strength and Durability

Don't let undercarriage failures cause costly downtime. Our premium Track Bolt and Nut set is specifically engineered to withstand the most abrasive and high-impact environments. Manufactured from high-tensile alloy steel and hardened to Grade 12.9 standards, this set provides the ultimate connection for your excavator's track chain, ensuring maximum service life and reliability.

Why Choose Our Grade 12.9 Track Bolt and Nut?

• Superior Grade 12.9 Hardness: The highest commercial grade, offering a minimum tensile strength of 1220 MPa. This translates to exceptional resistance to stretching, shearing, and fatigue under extreme loads.

• Excellent Wear Resistance: Precision threads and a hardened surface significantly reduce wear between the bolt and nut, preventing loosening and extending the life of both the fastener and the track chain bushings.

• Precision Engineering for Perfect Fit: Designed to meet or exceed OEM specifications for a seamless fit and optimal performance in your excavator's undercarriage system.

• Corrosion Protection: Treated with a durable phosphate or electro-zinc coating to resist rust and corrosion, even in wet or saline operating conditions.

• Complete Matched Set: Sold as the essential pair (Bolt: 6V1792, Nut: 1s1860) to ensure perfect thread engagement and uniform clamping force.

The Impact of Using High-Grade Undercarriage Fasteners

The undercarriage is the foundation of your excavator, and its fasteners are the critical links that hold it together. Using inferior bolts and nuts can lead to:

• Catastrophic Track Failure: A broken bolt can cause the entire track to separate, leading to immediate and dangerous operational halt.

• Accelerated Wear: Softer fasteners wear quickly, damaging the expensive track chain bushings and links.

• Increased Downtime: Frequent replacements for failed fasteners mean more time in the shop and less time on the job.

By investing in our Grade 12.9 set, you benefit from:

• Reduced Total Operating Cost: Fewer replacements and less damage to adjacent parts.

• Enhanced Job Site Safety: Minimizes the risk of sudden track failure.

• Improved Machine Uptime: Engineered for longevity, keeping your equipment productive for longer.

FAQ

Q1: What does "Grade 12.9" actually mean?
A: Grade 12.9 is a classification for high-strength steel fasteners. The "12" denotes a tensile strength of 1200 MPa, and the "9" indicates a yield strength ratio of 90% (1080 MPa). It is the strongest standard metric grade available.

Q2: Are the bolt and nut sold together?
A: Yes. This listing is for one (1) track bolt (6V1792) and one (1) matching track nut (1s1860) as a complete set. This ensures optimal performance.

Q3: How do I know if this fits my excavator?
A: The part numbers 6V1792 and 1s1860 are standard industry numbers. Please check your machine's parts manual or the old components you are replacing. When in doubt, contact us with your excavator model and serial number for verification.

Q4: What is the lead time for shipping?
A: We process orders within 1-2 business days. Shipping time depends on your location and the selected method. Please see our shipping policy page for detailed information.
