Metallics TS7810D Anchors 7/8 x 10 Wdg St-zn (Box 10)

Zinc plating on the TS7810D is a light corrosion coating meant for dry interior concrete work. For exterior, damp, or coastal anchoring, use a stainless steel or hot-dip galvanized wedge anchor in the same 7/8 inch diameter instead.

A wedge anchor is a mechanical expansion anchor for solid, poured concrete. You drill the hole, blow it clean, drop the anchor through the fixture, and tighten the nut, which pulls the cone into the expansion clip and wedges it against the hole wall. It is a one-shot anchor, not removable and not reusable. For hollow block, brick, or the web of a CMU wall, use a sleeve anchor or screw-type masonry anchor instead. For a bolt you want to remove later, use a drop-in anchor with a machine thread. At 7/8 x 10 inches, the TS7810D is a heavy structural size for things like column base plates, large equipment skids, and rack feet, not for light conduit or strut mounting.

Ten anchors per box. It ships as a box pack, so the quantity you order is in multiples of 10 pieces of the 7/8 x 10 inch anchor.

A wedge anchor of this style is supplied as a complete assembly: the threaded stud, expansion clip, cone, plus the hex nut and washer already on the threads. The 7/8 inch thread takes a 7/8 inch nut if you ever need to replace it. You will separately need a 7/8 inch carbide hammer-drill bit and a way to blow the hole clean.
