Tangless vs Tanged CoilThread Inserts

- Sep 07, 2017-

Tangless and tanged CoilThread inserts are helically-coiled fastening devices that provide permanent, wear-resistant threads, exceeding the strength of most parent materials. 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 (32 microinches) is exceedingly smooth, virtually eliminating friction-induced thread erosion.

Tangless and tanged CoilThread inserts are available in Unified Coarse (UNC), Unified Fine (UNF), and Metric thread sizes. CoilThread inserts can be manufactured using 304 Stainless Steel as well as Nitronic 60®, Nimonic 90®, Phosphor Bronze, and more.

Tangless vs Tanged CoilThread Inserts

Tangless CoilThread inserts are identical, in form, fit, and function to the conventional tanged inserts (CoilThread, Helicoil, Recoil). In fact, Tangless CoilThread inserts are identical to tanged inserts in every way except for their method of installation and removal, and they have the exact same procurement specification (NASM8846 for unified sizes and MA1565 for metric sizes).
