Premium Material: The thread repair kit with threaded inserts is made of excellent stainless steel, which has a higher hardness, making it strong and durable enough to withstand repeated use and frequent disassembly. Easy to Use: This thread repair kit is not easy to cut, provides deep threads, uniform force, no burrs in the threads, and a clean, tidy finish. It works by dispersing pressure from the machine body, protecting the threads and extending their lifespan indefinitely. Easy to Store: All screws are packed in a storage box, making them easy to use, find, and carry. This eliminates misalignment of screws and screw holes due to thread pitch and tooth type, and also absorbs vibrations. Numerous Applications: Thread repair kits can be used to repair stripped threads, improving the wear resistance of bolted joints and preventing thread damage. Widely used in the automotive, railway, marine, appliance, and many other industries. Package Contents: This threaded insert set includes 200 inserts from M3 to M8, meeting various needs. No pre-cutting is required; they can be directly screwed into the hole using an installation tool.
