There are two main advantages of rebar, as follows:

1. This material is widely used in building construction and decoration. It has high hardness and good durability. It can greatly improve the wear resistance of screw connections and effectively avoid damage to connecting threads. Due to the certain elasticity of the wire thread sleeve, it can make the load distribution on each circle of the thread more uniform, can eliminate the pitch and tooth shape deviation between the screw and the screw hole, and can also absorb vibration at the same time, so the use of rebar can improve the thread quality. connection strength and fatigue strength.

2. It has good shock resistance and firmness. Even when it is subjected to strong vibration, its screws will not loosen, which is better than the process performance of the usual locking device. This is because the locking type wire screw The sleeve can lock the screw in the threaded hole. The hardness of the wire threaded sleeve is higher than that of the screw, so it wears less during the assembly and disassembly process of connecting with the screw, and can be used repeatedly. Relevant experiments have proved that the tensile strength of the wire thread sleeve is more than 7 times that of the screw, so even if the screw breaks, the wire thread sleeve will not be damaged. Under the same strength conditions, it is suggested that you can choose screws with smaller size and higher strength, which can reduce the size and weight.
