The Parawedge anchor stud is cold formed and consists of a threaded section with standard coarse bolt threads at one end, and a parabolic mandrel at the opposite end for a smoother expansion. It has a 360° one-piece clip that functions as a two-piece clip for more contact, a torque controlled expansion, and can be installed into a bottomless hole. Three head styles are available - hex nut, wire hanger and tie-down hook.
