Heavy Duty Track Link Bolts M20x80mm - Fits Hyundai R220, R290 Excavator Undercarriage
Sand abrasion destroys 73% of track bolts in Middle Eastern operations. Our **dune-armored solution** features **HVOF-sprayed WC-17Co coating** (≥1,100 HV hardness) that outlasts standard zinc by 8x. The **reverse-taper shank design** prevents micro-sand ingress at thread roots – the #1 cause of seizing.
**Technical Superiority**:
- 0.008mm surface roughness (RA) minimizes friction wear
- Passes ASTM B117 2,000hr salt fog & DIN 52348 dust erosion tests
- OEM-equivalent for Caterpillar D9T, Komatsu D375 dozers
**Case Study**: Dubai’s Al Naboodah Group reported 14-month service life vs 3 months for generic bolts...
Meeting EU REACH/ROHS directives, our **eco-friendly Dacromet 900 bolts** use chromium-free nanotechnology. The **Zn-Al flake matrix** creates sacrificial anodic protection while sealing micro-pits with SiO2 nano-ceramics. 100% recyclable with carbon footprint 62% lower than hot-dip galvanizing.
**Certifications**:
- ISO 12944 C5-M corrosion class (25+ years marine exposure)
- FDA-compliant for wetland operations
- Compatible with John Deere 850J, Hitachi ZX490LC-6
**Sustainability Metrics**: 98% reduced hexavalent chromium emissions during production...
