2. Abrasion-Resistant Protection
Standard zinc plating fails within 200 hours in abrasive soils. Our Geomet® 3210 coating combines zinc-aluminum flakes with ceramic nanoparticles in a chromate-free matrix. Independent testing (ASTM D968) demonstrates 2,500+ hours salt spray resistance and 30% higher abrasion resistance than Dacromet. The 15-20μm coating withstands rock gouging during track articulation while maintaining 0.35μ surface roughness for consistent friction coefficients. Color-coded violet finish enables visual wear inspection without gauges.12.9 Alloy Steel M20X100 Anti-Break Track Shoe Bolts For CAT336 / Hyundai R29012.9 Alloy Steel M20X100 Anti-Break Track Shoe Bolts For CAT336 / Hyundai R290

1. Extreme Load Engineering
Track shoe bolts endure 5X higher shear loads than standard chassis bolts due to direct ground impact. Our M24x120mm bolts utilize quenched & tempered 42CrMoV4 steel (DIN EN 10269) achieving 1220MPa tensile strength. Proprietary cold-forging creates continuous grain flow in shank transitions, increasing fatigue resistance by 40% versus hot-forged alternatives. Finite element analysis confirms uniform stress distribution under 380kN cyclic loading - critical for 50+ ton excavators operating in rock excavation. Bolt head geometry incorporates 12-point flange design to prevent rotation during track flexing.
