Abstract

A helical-shaped insert to engage a threaded fastener to a receiving member includes a helical coil having a plurality of coil sections having inner and outer surfaces forming a thread shape, and opposing first and second coil end sections. A removable tang extends radially inward from the first coil end section. A continuously curved surface at a finished end of the second coil end section forms a tangent point where the continuously curved surface tangentially meets the second coil end section outer surface. A notch in the first coil end section proximate to the tang and positioned between the inner and outer surfaces permits removal of the tang by mechanical failure at the notch. A second notch in the second coil end section and the continuously curved surface assist coil removal.
