2. Drill the hole to the specified embedment depth and blow it clean using compressed air blower or a brush. Overhead installations need not be blown clean. Alternatively, drill the hole deep enough to accommodate embedment depth and dust from drilling.

3. Assemble the anchor with nut and washer so that the top of the nut is flush with the top of the anchor. Place the Welfast Wedge Anchor in the fixture and drive into the hole using a hammer until washer and nut are tight against the fixture.
