Caterpillar 320/336 Excavator Track Shoe Bolts, Komatsu PC220, Volvo EC290 - High-Strength Wear-Resistant Track Screws
Track shoe bolts designed for large excavators such as Caterpillar 320, 336, Komatsu PC220, PC270, Volvo EC290, EC360, etc., made of high-strength low-carbon alloy steel, treated with isothermal quenching, featuring both high strength and good plasticity to avoid brittle fracture under heavy load. The product is manufactured in strict accordance with original factory size standards, with clear thread profile and tight fit, which can effectively transmit track driving force and prevent relative displacement of track shoes. The surface is treated with phosphating and oiling, which is both rust-proof and convenient for lubrication during installation, reducing thread wear. The bolt length, diameter and other specifications are complete, which can directly replace the original parts without modifying the mounting holes. In heavy-duty operating environments such as mines and quarries, this bolt shows excellent wear resistance and fatigue resistance, significantly reducing equipment failure rates. Fully automatic testing equipment is introduced in the production process to ensure that each bolt's dimensional accuracy and mechanical properties meet the standards. As a cost-effective replacement part, this product reduces your equipment maintenance costs while ensuring operating efficiency. Technical consulting services are provided, customization of special specifications according to drawings is supported, and long-term cooperation is welcomed.
