AZ900396160051 Hollow Bolt

This hollow bolt is a special fastening and oil-through component for the oil circuit of Sinotruk gearboxes.

Precision forged and machined from high-strength alloy steel, it features high tensile strength, resistance to thread slipping and tooth breakage, as well as excellent pressure and vibration resistance.

The hollow bore is regular and smooth, ensuring unobstructed oil flow without deposition or blockage. The thread specification is standard and precise, enabling firm locking and preventing loosening.

With anti-rust and oil-resistant surface treatment, it boasts high temperature resistance and corrosion resistance, and is not prone to aging or oil leakage under long-term high-temperature and oily working conditions.

It perfectly matches the original mounting position with high interchangeability and easy assembly and disassembly. Featuring dual functions of fastening and oil circulation, it is an indispensable precision part for the maintenance and replacement of gearbox oil circuits.
