Product Description
12.9 Alloy Steel M20X100 Anti-Break Track Shoe Bolts For CAT336 / Hyundai R290
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
30% higher abrasion resistance than Dacromet
15-20μm coating withstands rock gouging during track articulation
Maintains 0.35μ surface roughness for consistent friction coefficients
Color-coded violet finish enables visual wear inspection without gauges
Extreme Load Engineering
Track shoe bolts endure 5X higher shear loads than standard chassis bolts due to direct ground impact.
M24x120mm bolts utilize quenched & tempered 42CrMoV4 steel (DIN EN 10269)
1220MPa tensile strength for maximum durability
Proprietary cold-forging creates continuous grain flow in shank transitions
40% increased fatigue resistance versus hot-forged alternatives
Finite element analysis confirms uniform stress distribution under 380kN cyclic loading
12-point flange design prevents rotation during track flexing
Engineered for 50+ ton excavators operating in rock excavation
