description

This M12×30 high-strength bolt is an OEM standard fastener for XCMG. Made of premium alloy steel with professional heat treatment, it delivers stable and reliable mechanical performance. Rolled threads feature continuous, full tooth profile and high fitting accuracy, resisting stripping after repeated disassembly. The black oxide surface forms a dense protective layer against rust caused by muddy water, asphalt dust and humid site conditions. Under long-duration, high-vibration paving operation, it maintains steady preload, firmly locks sheet metal parts and steel supports, minimizes clearance variation and reduces rattling, serving as a foundational fastener to secure guards and brackets.

FAQ

Q: Can a bolt with light surface rust stay in service?
A: It may be used temporarily if threads are intact. Replace it if seized, stretched or with rounded hex head.

Q: What causes thread stripping during tightening?
A: Excessive torque, worn threads, misaligned holes or insufficient strength. Stop tightening and install a new bolt.

Q: Can ordinary low-strength bolts be used as substitutes?
A: Not recommended. Low-grade fasteners easily loosen or fracture under sustained paving vibration.

Q: What should be noticed during installation?
A: Clean grit and asphalt residue from threads, tighten gradually to specified torque, and use anti-loosening washers at high-vibration positions.
