Simpson Strong-Tie Titen HD 5/8 In. X 6-1/2 In. Zinc-Plated Heavy-Duty Screw Anchor (10-Pack) THDB62612H - The Home Depot

The Easy-Set is a pin-drive expansion anchor for medium- and heavy-duty fastening applications into concrete and grout-filled block. Integrated nut and washer help keep track of parts. Drill the hole to the specified embedment depth plus 1/4 to allow for pin extension 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 through the fixture and into the hole.
