Feature:1. The wire thread insert is made of high-quality 304 stainless steel, which is resistant to high temperature and corrosion.2. The wire thread insert is made of steel wire, the exterior is glossy and there is no protrusion, and the thread expansion is more labor‑saving.3. In the event of thread processing errors or repairing damaged female threaded holes, thread sleeves are a good repair tool.4. The repaired thread screw is a fastener with certain elasticity, which can enhance the connection strength and fatigue strength of the thread.5. The repair nut is mainly used in aviation, automobiles, lamps, molds, mechanical equipment and other manufacturing fields.Specification:Item Type: Thread RepairMaterial: SUS304Model: M12 x 1.25Thread Specification: M12 x 1.25Outside Diameter Before Installation: Approx. 14.3-14.8mm / 0.56-0.58inDrill Bit Diameter: Approx. 12.3mm / 0.5in1D Length After Installation: Approx. 12mm / 0.5inNumber of Turns Before Installation: 7.51.5D Length After Installation: Approx. 18mm / 0.7inNumber of Turns Before Installation: 11.82D Length After Installation: Approx. 24mm / 0.9inNumber of Turns Before Installation: 16.12.5D Length After Installation: Approx. 30mm / 1.2inNumber of Turns Before Installation: 20.3Wire Thread Insert Model Description: For Example: M3 x 0.5 x 1.5D, which 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 is 1.5 times the diameter, that is, 1.5 x 3=4.5mm ), the length here refers to the length after installation.Wire thread inserts 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..Package List:20 x Thread Repair
