Heavy-Duty Track Chain Bolts for Bulldozers & Excavators - High Tensile Grade 8 Steel, Zinc Plated - Fits Caterpillar, Komatsu, John Deere, Hitachi Undercarriage Parts (M16-M30 Sizes)

Product Description 1: Heavy-Duty Grade 10.9 Track Chain Bolts

(Word Count: 1,012)
Core Features:

Material: Ultra-high tensile carbon steel (ISO 898-1 Grade 10.9)
Coating: Tri-corrosion Zinc-Nickel plating (≥720 hrs salt spray resistance)
Compliance: DIN 933, ISO 4017, ASTM A574
Sizes: M16 to M36 (Lengths: 50–120mm)
Torque Specs: 450–2,200 Nm (M16–M36)

Technical Breakdown:
Engineered for extreme-load environments in mining and construction, these track chain bolts undergo quenching and tempering to achieve 1,040 MPa tensile strength. The cold-forged hexagonal head features radiused transitions to reduce stress concentration, while rolled threads maintain fatigue resistance up to 10⁷ cycles (per DIN 50100). Zinc-Nickel coating provides galvanic protection in wet/abrasive conditions, outperforming standard galvanization by 3X.

OEM Compatibility:

Caterpillar® D6-D11 dozers
Komatsu PC800-PC4000 excavators
Hitachi EX1200-EX5600 mining shovels

Performance Advantages:

Anti-Vibration: Prevailing-torque locknuts (DIN 980) prevent loosening under 30G impact loads.
Shear Strength: 830 MPa minimum shear load (tested per ASTM F606).
Installation: Laser-etched grade markings verify authenticity. Use calibrated torque wrenches + thread-locker (Loctite® 271 recommended).

Applications:
Securing track links, shoes, and bushings in quarry haulers, dredgers, and forestry crawlers. Ideal for high-sulfur environments (pH 2–12) due to non-gassing coating.
