Thread Repair Cutter Kit Helicoil Set - 3/8" x 16 BSW

This kit is specifically designed for 3/8" x 16 BSW (British Standard Whitworth) internal threads.

The inserts are made of stainless steel, providing high strength, durability, and rust resistance.

No, this kit is exclusively for 3/8" x 16 BSW threads and is not compatible with metric or other imperial thread sizes.

The tang is a small projection on the insert that helps screw it into the tapped hole. It is designed to be snapped off and removed after installation.

The strength comes from the stainless steel insert creating a new, robust thread. Ensure the insert is fully seated and properly installed according to the instructions.

A standard tap creates threads, while this kit first enlarges the damaged thread (drilling), then cuts a new thread specifically for the helicoil insert, which then reinforces the original thread size.

The kit includes 10 x 3/8 x 16 BSW inserts.

Ensure the drill bit is sharp and clean. Use adequate pressure and consider using cutting fluid, especially when drilling into harder metals.

Back the tap out frequently (a quarter turn) to clear chips. Use cutting fluid. Ensure the pilot hole is drilled to the correct size and is perpendicular to the surface.

Verify the correct thread tap was used for the insert size. Ensure the hole was drilled to the correct diameter. Clean any debris from the tapped threads before installing the insert.

Ensure the tang is fully seated within the insert before attempting to break it. Apply firm, direct pressure. If necessary, a small punch can be used to dislodge a stubborn tang.
