Feature: 1. THREAD REPAIR KIT: This thread repair kit is the perfect solution for repairing damaged or stripped thread holes. It forms greater internal threads in soft metals, protecting tapping threads from wear and damage. 2. COMPLETE TOOL: The repair kit includes an installation tool, 50PCS steel thread inserts, a tap drill bit, a tap, and a punch tool. With a convenient storage box, you can easily collect and retrieve the tools. 3. FUNCTION STEEL THREAD INSERTS: The steel thread inserts are specifically designed for low strength materials like aluminum. They prevent thread damage and provide excellent connection performance, enhancing strength and improving the overall connection condition. 4. ENHANCED LOAD DISTRIBUTION: Due to their elasticity, the thread inserts evenly distribute the load across the threads, eliminating pitch and tooth profile deviations between the screw and the hole, absorbing vibrations, increasing thread connection strength and fatigue resistance. 5.
