Metric Thread Repair Kit, 304 Stainless Steel Wire Inserts, 210 Pcs | 304 Stainless Steel Helical Inserts for Automotive & Machinery. M3-M12 2D Sizes for Rebuilding Stripped Internal Threads

Saved me when I stripped out a caliper bolt on my wife's jeep. Have plenty more for future use should I ever need it. Very sturdy build quality too.

The kit contains a decent assortment of good quality coils. I used some to re-mount the starter to a riding mower. Loose bolts that wiggled each time the mower was started had stripped the threads from the holes in the engine block until the starter fell loose. These coils allowed me to repair the issue with a durable solution that could stand up to the vibrations and heat that made other options fail without having to re-tap the block to a larger bolt size, which would have not fit through the holes in the starter. Take time to do your homework and make sure you are using the right size.

Muy util

I used this wire thread sleeve kit to repair two screw holes, and I’m impressed with its comprehensive design. The case offers an extensive range of options, far more than needed, which is a genuine advantage. Its durability suggests it could last for years, making it a fantastic long-term investment.

Went beyond meeting my expectations!

Necesitaba reparar unas roscas de mi vieja Ford Ecosport que usa un motor Duratec 2.0 Lastimosamente los mecánicos en Venezuela suelen dañar las roscas, por lo que dije que las repararía por mi cuenta y funciono, no me tomo mas de 20 minutos reparar las roscas de todos los tornillos de la tapa de la cámara de compresión. Lastima que no habían M7x1 los compre en otro Kit para reparar los sujetadores del árbol de levas. Todo perfecto.

Perfect.

Buen servicio. Gracias
