Feature:1. The repair nut is an industrial fastening part, which is mostly used with screws or bolts.2. When thread processing error occurs or female threaded hole is damaged, the wire thread insert is a good maintenance tool.3. 304 stainless steel has good corrosion resistance and is not easy to break when repairing threaded holes.4. The thread size is standard, the thread is clear, and it will be more accurate for thread sliding tooth restoration.5. Commonly used in hydraulic machinery, welding equipment, auto parts, power machinery and furniture, etc.Specification:Item Type: Thread RepairMaterial: SUS304Model: M12 x 1.5Thread Specification: M12 x 1.5Outside Diameter Before Installation: Approx. 14.3-14.8mm / 0.56-0.58inDrill Bit Diameter: Approx. 12.4mm / 0.5in1D Length After Installation: Approx. 12mm / 0.5inNumber of Turns Before Installation: 6.21.5D Length After Installation: Approx. 18mm / 0.7inNumber of Turns Before Installation: 9.8 2D Length After Installation: Approx. 24mm / 0.9inNumber of Turns Before Installation: 13.52.5D Length After Installation: Approx. 30mm / 1.2inNumber of Turns Before Installation: 17.1Wire 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
