This item is replaced by an item number: BA-TL15043-RE

Kato Tangless and tanged CoilThread inserts are helically-coiled fastening devices that provide permanent, wear-resistant threads, exceeding the strength of most parent materials. Kato Tangless and tanged CoilThread inserts are used extensively in aircraft applications, such as engines, gear boxes, fuel systems, radar, avionics, flight controls, lighting and HVAC systems. They are also used widely by the military and in many other electronic, mechanical, and commercial applications. The Kato Tangless, FOD-free design is the preferred standard for optimum thread assemblies in new fastening system designs.

• This is the most popular insert material, and it will satisfy most application requirements for strength, corrosion resistance and temperature capability
• The inserts can be used in applications with a temperature range from -320° F to 800° F
• Cold rolling the stainless steel wire to a diamond shape work-hardens it to a tensile strength above 200,000 PSI, a hardness of Rc 43-50 and a smooth 8-16 micro-inch finish
• The inserts become slightly magnetic from the work-hardening that occurs during the manufacturing process (approx. 2-10 G/O)
• The insert material is covered by specifications AS7245, NASM8846 and alloy number UNS S30400
