Installing a wedge anchor can be accomplished in three steps: 1.Drill a hole in the concrete using a hammer drill and a carbide tipped masonry drill bit conforming to ANSI B94, 12-77, the same diameter as the ThunderStud® wedge anchor. If the fixture being fastened is in place and being used as a template to locate the hole for the ThunderStud® anchor, the mounting hole in the fixture should afford clearance for the universal wedge clip on the stud. 2. Clear the hole of all debris, then place the ThunderStud® wedge anchor through the hole in the fixture or directly into the concrete, and hammer it into the drilled hole, ensuring that they are installed to the desired depth. 3. Turn the nut by hand until the unit is “snugged up”. Tighten the nut with a torque wrench to ensure they are tightened to the required torque value.
