Item Type: Wire Thread InsertMaterial: SUS304Model: M24 x 3 x 3DThread: M24 x 3Length After Installation: Approx. 72mm / 2.8inCircle Number Before Installation: 21.2Outside Diameter Before Installation: Approx. 28.5 x 29.1mm / 1.1 x 1.12inDrill Bit Diameter: Approx. 24.8mm / 1inWire Thread Insert Specification Description: For Example: M3 x 0.5 x 1.5D, which means that after the screw set is completed, the internal thread is M3, the pitch is 0.5, and the length is 1.5D (length refers to 1.5 times the diameter, that is, 1.5 x 3=4.5mm ), the length here refers to the length after installation.Wire screw sleeves 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 List5 x Wire Thread Insert 1The thread sleeve is female thread fastener with certain elasticity, which can enhance the connection strength and fatigue strength of the thread. 2Fit the sleeve set in the screw hole of the metal material workpiece to form a highaccuracy standard female thread. 3When a thread processing error occurs or a damaged female threaded hole is repaired, the thread sleeve can effectively repair the thread hole. 4Stainless steel has good corrosion resistance and is not easy to break when repairing threaded holes. 5The screw sleeve can be used to convert between metric and imperial threaded holes, which is convenient and fast.
