Creating strong joints from lightweight materials for more than 25 years.

Friction-free. Almost.

Our materials range from standard stainless steel through to Nimonic 90, Nitronic 60, Inconel X750 and Phosphor Bronze. Various surface finishes are available, including Cadmium plating, Silver plating, and Dry Film Lube.


Cold-rolled quality.

Our inserts are manufactured from work-hardened, stainless steel, forming an exceedingly smooth and hard surface that reduces thread wear and resists corrosion. This results in a highly reliable, long-life insert.


Fully traceable.

With many years of manufacturing and engineering experience, the Tanged range of inserts meet all applicable industry standards with full traceability.

KATO® Tanged wire thread inserts have become an industry-standard solution from decades of design innovation, engineering and industry use.

They offer quality and performance through the use of high-grade materials, and provide bespoke solutions through a selection of sizes, coatings and materials.

Our Tanged wire thread inserts have been used across aerospace, automotive and electronic industries, providing strong and reliable solutions for lightweight and soft materials.

Versatile to suit every design

At KATO®, we strive to offer precision engineered solutions for every situation and application. Our Tanged wire thread inserts are available in both metric (M2 to M16) and unified (0-80 to 1/2-20) size ranges. The entire range is also available in both free running and locking styles with five standard lengths (1D, 1.5D, 2D, 2.5D, 3D). This ensures that manufacturers can find the optimum-sized insert no matter what the application. Moreover, the materials we manufacture include Stainless Steel, Nitronic 60, Nimonic 90, Inconel X750, and Phosphor Bronze.

Reliability for long-term performance

KATO® Tanged wire thread inserts use high-integrity, wear-resistant threads that exceed the strength of most parent materials. Our Tanged wire thread inserts are put through rigorous testing, comprehensive dimensional inspection and metallurgical analysis to ensure strength and reliability.
