1When there is a thread processing error or a damaged female thread hole is repaired, the wire thread insert can be used as a repair tool. 2The thread repair socket is made of stainless steel, has high strength, and is not easily deformed during thread repair. 3The wire thread insert has certain elasticity, can disperse pressure to protect the thread of the base body, and prolong the service life of the base body. 4The wire threaded socket is female thread fastener with certain elasticity, which can enhance the connection strength of the thread. 5The repair nut is mainly used in aviation, automobiles, lamps, molds, mechanical equipment and other manufacturing fields.Item Type: Wire Thread Insert_x000D_Material: SUS304_x000D_Standard: US Units_x000D_Model: 1/4in-20_x000D_Diameter: Approx. 6.35mm / 0.25in_x000D_Pitch: Approx. 1.27mm / 0.05in_x000D_Outside Diameter Before Installation: Approx. 7.8-8.3mm / 0.31-0.33in_x000D_Drill Bit Diameter: Approx. 6.6mm / 0.26in_x000D_Thread Protective Socket Model Specification Description: For Example: M3 x 0.5 x 1.5D means that after the screw set is completed, the female thread is M3, the pitch is 0.5, and the length is 1.5D (length refers to 1.5 times the diameter, that is, 1.5 x 3=4.5mm) , the length here refers to the length after installation._x000D_Wire thread inserts are also called threaded sheaths, stainless steel threaded sockets, wire sockets, and braces. They are a new type of female threaded fasteners made of high-strength, high-accuracy diamond-shaped cross-section steel wires; Application to low-strength engineering materials such as aluminum alloy, zinc alloy, copper, plastic, etc., can significantly improve thread strength and wear resistance.50 x Wire Thread Insert
