Why choose this product

Precision Engineering for Stronger Threads

Ideal for Automotive & Metalwork

This kit is perfect for mechanics, DIY enthusiasts, and workshops needing to repair stripped or worn threads in aluminum, iron, carbon steel, and bronze.

Use the matching HSS tap provided in the kit to cut new, clean threads into the drilled hole. Ensure the tap is perpendicular to the surface and use cutting fluid for smoother operation and tap longevity. — Tap New Threads
Thread the 304 stainless steel insert onto the installation tool. Screw the insert into the newly tapped threads until it is slightly below the surface. Use the break-pin tool to snap off the tang. — Install the Thread Insert
