What is the difference in performance between hexagon socket cylinder head bolts and other bolts?

1. Load-bearing capacity of hexagonal cylinder head bolts
High performance and strength: usually made of alloy steel or stainless steel, the tensile strength can reach 10.9 or 12.9 after heat treatment, which can withstand the high temperature, high pressure and vibration load of the engine during operation.
Uniform force: The hexagonal design makes the bolt head evenly stressed, reduces stress concentration, and is suitable for industrial scenarios with high preload requirements.

2. Convenient installation of hexagonal cylinder head bolts
Low space requirements: The hexagonal design only requires a small operating space, which is suitable for use in scenarios with limited space such as engine cylinder heads.
Precise torque transmission: The hexagonal wrench can accurately control the torque, improve the accuracy of operation, and ensure uniform distribution of preload.
Countersunk head design: The head can be completely embedded in the component, keeping the surface flat, avoiding interference with other parts, and is beautiful and convenient.

3. Adaptability of hexagonal cylinder head bolts
High temperature and high pressure resistance: High-strength material and surface treatment are used, suitable for use in special environments such as engines.
Good anti-seismic performance: Through high-precision manufacturing and preload control, loosening caused by vibration is reduced to ensure normal operation.
