100pcs M2.5-0.45×1.5D Metric 304 Stainless Steel Helicoil Type Thread Repair Insert, Wire Thread Insert

★ Dimension description: for example: M3×2D(0.5) M3 means the thread diameter is 3mm, thread pitch is 0.5mm, ★ 2D indicates that the maximum length of the Helical Insert after installation is 2 times of the diameter。 ★ Strengthen the connection strength and improve the connection conditions. Low strength materials such as aluminum and magnesium shall be used for the steel wire screw sleeve. Thread slipping can be avoided. Tooth dislocation. Excellent connection performance is obtained. ★ Wear resistance. Frequently disassembled parts can greatly improve the service life of the thread. ★ Increase the bearing surface. It is used for parts that require strong coupling force but cannot increase the diameter of screw hole. ★ Anti loosening. Especially for products requiring high safety factors such as spacecraft. ★ Easy to maintain. Install the damaged screw hole into the steel wire screw sleeve and use it again after repair to avoid the possibility of workpiece damage. ★ Installation method of steel wire screw sleeve 1. Use standard drill through to drill holes first. 2. Use a special tap for tapping. Note that the tapping length should be longer than the length of the steel wire thread sleeve. 3. Clean the holes with compressed air gun. 4. Use a wrench to insert the mounting handle into the core groove, and rotate the wrench to apply pressure on the screw sleeve and rotate the thread into the bottom hole of the thread. 5.
