Product Description
Heavy Duty Track Link Bolts M30X150 For Volvo EC210 / Kobelco SK250
Extreme Load Engineering
Track shoe bolts endure 5X higher shear loads than standard chassis bolts due to direct ground impact. Our M24x120mm bolts feature:
- 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
- 12-point flange design prevents rotation during track flexing
Abrasion-Resistant Protection
Our Geomet® 3210 coating provides superior protection:
- Combines zinc-aluminum flakes with ceramic nanoparticles in chromate-free matrix
- ASTM D968 testing shows 2,500+ hours salt spray resistance
- 30% higher abrasion resistance than Dacromet
- 15-20μm coating withstands rock gouging while maintaining 0.35μ surface roughness
- Violet color-coding enables visual wear inspection
Precision Manufacturing Protocol
Our rigorous production process ensures exceptional quality:
- CNC machining maintains ±0.015mm dimensional tolerance (DIN 6921)
- Thread rolling after heat treatment increases fatigue strength by 25%
- 100% automated optical inspection verifies:
- 6g thread fit per ISO 965-1
- Rockwell C33-39 hardness gradient
- 0.02mm max head-to-shank concentricity
- Laser-etched QR codes provide full traceability including furnace batch and heat treatment data
