M22X110 Arctic Track Bolts for Komatsu PC300 / LiuGong 925F w / Shakeproof Washers

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.
