Bulk Pack Track Chain Fasteners: High-Quality Link Bolts with Hex Nuts for Crawler Excavator & Dozer Track Repair - Optimal Torque Specs, Wear Resistance, Reduced Vibration Loosening
These bolts resist oxidation, creep deformation, and thermal cycling fatigue in environments where standard steel fasteners fail. The A286 core's gamma-prime precipitates maintain 85% tensile strength at 600°C vs. 35% for Grade 8.8 steel. Aluminized coating forms a stable α-Al₂O₃ barrier, reducing scale formation by 90% (tested per ASTM G54). Rolled threads with UNJ profile (MIL-S-8879) prevent stress-cracking under rapid quenching scenarios.
