BOLT

An eccentric bolt is a special type of bolt designed to provide a strong and adjustable connection between two components. Unlike regular bolts, which have a uniform diameter throughout their length, eccentric bolts have a portion of their shaft offset from the center line. This unique design allows for precise adjustments and fine-tuning in applications where alignment and positioning are critical.

Camber alignment bolts are for adjusting the angle during 4-wheel alignment, the wheel camber is out of the standard range of use and can only be adjusted by using Camber Alignment Bolts. The use of Camber Alignment Bolts ensures that the wheel data is normal and avoids tire wear without compromising safety.

DIN 931 standard specifies partially threaded hexagon head bolts.The specifications include details such as material,thread type, length, head type, and strength class. DIN 931 hex bolts are commonly made from steel or stainless steel, metric coarse threads, and are available in various lengths. The hexagon head allows for easy tightening with a wrench or socket. Different strength marks like 8.8 or 10.9 indicate the bolt's tensile strength. 

The wheel bolt is to serve as a component for installing the axle, supporting the tire, buffering external impacts, achieving contact between the tire and the road surface, transmitting the weight of the vehicle to the road surface, bearing the lateral load, driving force, and braking torque during turns, and ensuring the driving performance of the vehicle.

Wheel bolts are high strength, usually made of carbon steel or alloy steel.The grade depending on the vehicle model and load capacity, class 10.9 is most popular.The structure can generally be divided into knurled and threaded ones. Wheel bolts have the characteristics of high strength and wear resistance.

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.
