Wire Inserts
Tangless and tanged inserts are helically-coiled fastening devices that provide permanent, wear-resistant threads, exceeding the strength of most parent materials. Wire inserts are typically 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 inserts are available in Unified Coarse (UNC), Unified Fine (UNF), and Metric thread sizes. Inserts can be manufactured using 304 Stainless Steel as well as Nitronic 60®, Nimonic 90®, Phosphor Bronze, and more.
