Heavy-Duty Greaseable Track Bolt Assembly - This integrated bolt-nut system incorporates a central grease channel design (0.8mm diameter) allowing lubrication without disassembly. Manufactured from 20MnTiB boron steel with carburized case depth of 0.8-1.2mm, achieving 60-62 HRC surface hardness.
The corrosion-resistant Dacromet coating passes 1,500-hour neutral salt spray testing. Specifically designed for Komatsu PC200-8 undercarriages, it reduces rotational friction by 35% compared to standard bolts. Includes a castellated nut with cotter pin hole for redundant safety locking.
