Item Type: Wire Thread Insert_x000D_ Material: SUS304_x000D_ Model: M3.5 x 0.6_x000D_ Thread Specification: M3.5 x 0.6_x000D_ Outside Diameter Before Installation: Approx. 4.5-4.8mm / 0.18-0.19in_x000D_ Drill Bit Diameter: Approx. 3.7mm / 0.1in_x000D_ 1D Length After Installation: Approx. 3.5mm / 0.1in_x000D_ Number of Turns Before Installation: 4_x000D_ 1.5D Length After Installation: Approx. 5.3 mm / 0.2in_x000D_ Number of Turns Before Installation: 6.4 _x000D_ 2D Length After Installation: Approx. 7.0mm / 0.28in_x000D_ Number of Turns Before Installation: 8.9_x000D_ 2.5D Length After Installation: Approx. 8.8mm / 0.35in_x000D_ Number of Turns Before Installation: 11.4_x000D_ 3D Length After Installation: Approx. 10.5mm / 0.4in_x000D_ Number of Turns Before Installation: 13.9_x000D_ 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._x000D_ 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.
