Drill the hole to the specified embedment depth, and blow it clean using compressed air. (Overhead installations need not be blown clean.) Alternatively, drill the hole deep enough to accommodate embedment depth and the dust from drilling. Place the anchor in the fixture, and drive it into the hole until the washer and nut are tight against the fixture. Tighten to required installation torque. 。 。 。
