High strength bolts are with high tensile strength and fatigue strength, usually made of alloy steel material. Their main function is to fasten the fuselage plate and accessories to the engine to ensure safe and stable operation of the engine.
These bolts securely fasten infrastructure that requires high-tensile strength.They are bolts with a performance level of 8.8 or above. High strength bolts can withstand loads greater than ordinary bolts of the same specification.The material of high strength bolts is 35 # steel or other high-quality materials, which with heat treatment to improve strength.
