Tanged CoilThread inserts are made of cold-rolled 304 stainless steel wire (AS7245), work-hardened to a tensile strength above 200,000 psi, and a hardness of Rc 43-50. The finished surface (8-16 micro-inches) is exceedingly smooth, virtually eliminating friction-induced thread erosion.

The stainless steel used resists corrosion under normal environmental conditions. Galvanic action within the thread assembly is reduced, further adding to the life of the fastening assembly. KATO Inserts are used with temperatures from -320°F to +800°F (-195.6°C to +426.7°C).

Tanged inserts install into the BS4377 tapped holes to accept ISO metric threads conforming to BS364: Part 1: 1981 and BS364: Part 2: 1981. Metric Tanged CoilThread inserts conform to National Bureau of Standards Handbook H-28/21, M Profile, Tolerance Classes 4H5H or 5H, as well as ISO standards 68, 261, R724 and 965/I.

 

Assembled metric Tanged Coilthread will also accommodate MJ, AS1370 and DIN male threaded fasteners.

When assembled with STI-tapped holes, Tanged CoilThread inserts form Unified Coarse, or Unified Fine threads that conform to the National Bureau of Standards Handbook H-28, Screw-Thread Standards for Federal Services, Classes 2B and 3B. Assembled Tanged CoilThread inserts will also accommodate UNJ, MIL-S-8879, male threaded fasteners.
