Helical Insert Thread Repair Kits

Thread repair using CoilThread Inserts is a universally accepted method of repairing stripped threads in all types of metals and other materials. Damaged threads can be brought back to the original thread size, and better than new using stainless steel inserts. Thread wear, corrosion and galling will be virtually eliminated, and the assembly will be stronger than the original with CoilThread Inserts.

Unlike threaded solid bushing type fasteners, CoilThread Inserts provide space and weight savings to your repair process. In addition, CoilThread Inserts eliminate the need for oversized drilling and tapping, and welding or plugging of damaged holes. Kato CoilThread inserts are 100% compatible with Heli-Coil®  Inserts.

At KATO there is only one standard of quality for original equipment or repair inserts...All KATO CoilThread Inserts meet or exceed all applicable military, aerospace, and commercial standards.

Each individual KATO-KIT thread size consists of:

  • Twelve, six, or four KATO Tanged CoilThread Inserts (see chart for details) in the most popular length (1-1/2 Diameter).
  • 1 High-speed steel STI tap.
  • 1 High quality threaded installation tool (mandrel made from steel not plastic)
