Item Type: Thread Repair Material: SUS304 Model: M14 x 1.25 Thread Specification: M14 x 1.25 Outside Diameter Before Installation: Approx. 16.7-17.2mm / 0.66-0.68in Drill Bit Diameter: Approx. 14.3mm / 0.6in 1D Length After Installation: Approx. 14mm / 0.6in 1.5D Length After Installation: Approx. 21mm / 0.8in 2D Length After Installation: Approx. 28mm / 1.1in 2.5D Length After Installation: Approx. 35mm / 1.4in 3D Length After Installation: Approx. 42mm / 1.7in 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.
