Tanged Helical Inserts


Tanged Helical Inserts | Buy Tanged Free Running & Screw Lock Inserts - Bay Supply Fasteners and Fastening Systems Tanged Helical inserts or Tanged Helicoil inserts have a straightened end called a “Tang” that crosses through the inside diameter of the fastener and is used to complete the installation process. The Tang is broken off of the coil thread fastener after installation.


CoilThread tanged 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.
