Features Industrial Fastening Part: The repair nut is an essential industrial fastening part, commonly used with screws or bolts, ensuring secure and reliable connections in various applications. Efficient Thread Restoration: When encountering thread processing errors or damaged female threaded holes, the wire thread insert provides a reliable solution for effective maintenance, preserving the integrity of the original threads. Accurate Thread Size: With standard thread size and clear threading, the wire thread insert ensures restoration of thread sliding tooth, maintaining accuracy and consistency in threaded connections. Stainless Steel Construction: Constructed from 304 stainless steel, the wire thread insert offers excellent resistance, ensuring long-lasting performance and reliability in repairing threaded holes. Versatile Compatibility: The wire thread insert facilitates seamless conversion between metric and inch threaded holes, providing a convenient and quick solution for a wide range of applications. Specification: Item Type: Thread Repair Material: SUS304 Model: M12 x 1.75 Thread Specification: M12 x 1.75 Outside Diameter Before Installation: Approx. 14.3-14.8mm / 0.56-0.58in Drill Bit Diameter: Approx. 12.4mm / 0.5in 1D Length After Installation: Approx. 12mm / 0.5in Number of Turns Before Installation: 5.3 1.5D Length After Installation: Approx. 18mm / 0.7in Number of Turns Before Installation: 8.4 2D Length After Installation: Approx. 24mm / 0.9in Number of Turns Before Installation: 11.6 2.5D Length After Installation: Approx. 30mm / 1.2in Number of Turns Before Installation: 14.8 3D Length After Installation: Approx. 36mm / 1.4in Number of Turns Before Installation: 18 Wire 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.
