Features Used in various low-strength materials, which can improve the wear resistance of bolted assemblies and avoid damaging the thread. The hardness of the thread screw is higher than that of the screw, so it has little wear in relation to the screw and can be used repeatedly. Strengthen the connection strength and improve the condition of the connection, avoid wire slipping, bad tooth phenomenon and get excellent connection performance. Due to a certain elastic, can make the load on the thread more uniform, eliminate the deviation of the screw and screw hole between the pitch and the tooth type, and can absorb vibration, thereby increasing the thread connection strength and fatigue resistance. The lockable type metal screw sleeve can lock the screw in the threaded hole, so that the screw will not loosen when subjected to shock vibration, which is better than the normal locking device Description: Wire screw sleeve is a new type of fastening technology that can effectively improve the connection conditions and greatly increase the reliability of the screw connection. Features: Used to place this solid connection without increasing the diameter of the screw hole. Wear-resistant. Used for frequent disassembly, it can greatly improve the service life of the thread.Anti-loose. Especially for aircraft and other products requiring high insurance coefficients.Easy to maintain. Damaged screw holes should be placed in the thread screw sleeve, which can be reused to avoid the risk of damage to the part. Features: Material: stainless steel.
