There’s quality, and then there’s KATO® Quality.

Manufactured with an exceedingly smooth finish that effectively eliminates friction-induced thread erosion. KATO® wire thread inserts are built to stand the test of time, over many cycles.

No one makes stronger joints

Lightweight joints have never been stronger. KATO® helically-coiled fastening devices create permanent, wear-resistant screw threads that exceed the strength of the parent material.

Smooth, rugged and robust

Finished exceedingly smoothly to eliminate friction-induced thread erosion. At just 32 microinches, KATO® fastening devices meet and even exceed the requirements of applicable military, aerospace and commercial standards.
