Feature 1In the event of thread processing errors or repairing damaged female threaded holes, thread sleeves are a good repair tool. 2304 stainless steel has good corrosion resistance and is not easy to break when repairing threaded holes. 3The repaired threaded screw is a fastener with a certain degree of elasticity, which can enhance the connection strength and fatigue strength of the thread. 4Wire thread inserts can be used to switch between metric and inch threaded holes, which is convenient and quick. 5Repair nuts are mainly used in aviation, automobiles, lamps, molds, mechanical equipment and other manufacturing fields. Item Type: Wire Thread InsertMaterial: SUS304Model: M1/12-13 x 1DPurpose: For threaded connectionOutside Diameter Before Installation: Approx. 15.1-15.7mm / 0.59-0.62inLength After Installation: Approx. 12.7mm / 0.5inCircle Number Before Installation: 5.2Drill Bit Diameter: Approx. 13.2mm / 0.5inWire Thread Insert Specification Description: For Example: M3 x 0.5 x 1.5D, which means that after the screw set is completed, the internal 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.Wire screw sleeves are also called threaded sheaths, stainless steel threaded sleeves, wire sleeves, and braces. They are a new type of internal 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.
