• Made of stainless steel, with certain elastic and even load so that it is resistant to vibration, thus increasing the screw thread connection strength and fatigue resistance.
• Because of a certain elastic, can make the load on the thread is more even, eliminate the screw and screw hole deviation between the pitch and tooth type, and can absorb vibration, thus increasing the screw thread connection strength and resistance to fatigue strength.
• The locking type wire screw sleeve can lock the screw into the threaded hole, so that the screw is not loose when subjected to shock vibration, which is better than the normal locking device.
• The hardness of the wire screw is higher than the screw, so it has little wear and tear in connection with screw,and can be used repeatedly.
• Used for aviation, automobiles, steam turbines, electronic communications, computers, lamps, molds, mechanical equipment, radiators, and semiconductor equipment etc.
