Track Link Bolt for Excavators

Name: Track Link Bolt for Excavators
Brand: YONGYI

Product Introduction Excavator track plate bolts are heavy-duty specialized fasteners engineered for the extreme working conditions of excavator undercarriages, forged from high-grade alloy steel and refined through quenching and tempering heat treatment. They feature a thickened shank design and a high-strength hexagonal or countersunk head structure, which can withstand intense impact, heavy load and continuous vibration during excavation operations. The thread section of the bolt is precisely rolled to ensure tight engagement with track plate nuts, effectively preventing loosening caused by equipment jolting and harsh terrain friction. The surface is treated with advanced anti-corrosion and wear-resistant processes such as hot-dip galvanizing, dacromet coating or ceramic spraying, which significantly enhances resistance to rust, mud erosion and mechanical abrasion, extending the service life of the fasteners in harsh construction environments. Product Application Primarily used for fastening the track plates and track shoes of various types of excavators, securely connecting the undercarriage components to ensure the stable operation of the equipment during excavation, trenching and lifting tasks. They are also widely applied in the maintenance and replacement of undercarriage parts for construction machinery such as bulldozers and crawler loaders, serving as a critical core fastener to guarantee the structural stability of crawler undercarriages and prevent potential safety hazards caused by track plate detachment.
