Use these inserts to install fine-thread screws in existing holes.

These inserts come with an installation tool. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts.

A distorted thread grips the screw to resist loosening.

A black-phosphate finish provides mild corrosion resistance.

Install these inserts into a compatible holder to cut external or internal threads on a workpiece.

These tools come with one high-speed steel insert for use on steel and stainless steel and one high-speed steel insert for use on softer materials, such as aluminum and brass. When one point of an insert dulls, rotate it to use a sharp point.

Solid carbide provides more rigidity than carbide-tipped tools.

The carbide tip brazed onto the ground steel shanks of these tools is more wear resistant than high-speed steel.

Cut threads in plastic and most metal with these high-speed steel tools.
