D-Series Anti-Loosening Bolts for Shantui SD32 Bulldozers, SD42 Bulldozers - Blade Lifting Mechanism Connecting Bolts, High-Strength and Vibration-Resistant
According to the working characteristics of the blade lifting mechanism of Shantui SD32 and SD42 bulldozers, this D-series anti-loosening bolt adopts a unique anti-loosening design, combined with a special thread structure, which can effectively prevent loosening during frequent lifting operations of the blade. The bolt is made of high-strength steel, after quenching and tempering treatment, the yield strength reaches more than 800MPa, with excellent bearing capacity. Its surface is phosphated to increase the friction coefficient and make the connection more firm. The bolt is easy to install, and can ensure the stable operation of the blade lifting mechanism without additional anti-loosening measures, which greatly reduces the maintenance cost and is suitable for various complex earthwork operation environments.
