Track Bolt & Nut – Xiamen Doozer Construction Machinery Co.,Ltd

Track Bolt & Nut

1、Grade 12.9 Strength – Break & Shear Resistant
High-strength alloy steel + precision heat treatment withstands extreme impact and heavy loads, completely eliminating bolt breakage or thread stripping.
2、Superior Anti-Loosening – Stays Tight Forever
Special thread profile + dual locking mechanism (or compatible wedge/self-locking design) delivers far superior clamping force under vibration/impact → reduces loosening risk by over 90%.
3、High Reusability – No Hole Enlargement
Premium surface hardening + tight thread tolerance prevents repeated torquing from enlarging shoe bolt holes, protecting links and track shoes from early scrap.
4、Corrosion & Wear Resistant
Dacromet / hot-dip galvanizing finish resists moisture, mud, sand, and salt-alkali corrosion → 2–3× longer service life, no rust seizure.
5、Perfect Fit for Major Brands – Install & Go
Exact match to Caterpillar, Komatsu, Hitachi, XCMG, Shantui bolt specs → zero thread mismatch, stable torque, fast installation with no rework.
6、Lower Total Maintenance Cost
One-time reliable replacement lasts much longer → drastically cuts downtime from loose bolts causing track derailment or chain damage, saves money long-term.
