"Wedge anchor" is a generic term for a type of anchor used to fasten a variety of materials to concrete. Some companies have different brand names for their wedge anchors such as Kwik Bolt, Power Stud, and Thunderstud.
A 5/8” concrete wedge anchor requires a 5/8” hole to be drilled into the concrete. The hole in the concrete needs to be drilled a minimum of 1/2” deeper than the concrete wedge anchor will penetrate into the concrete.
