Metallics LCSX5850 Anchors 5/8 x 5 Hx Hd Lg Dia CS St-Gv (Box 10)

It's a one piece large diameter concrete screw. The hex head anchor threads directly into a pre-drilled hole in concrete, so there's no sleeve, wedge, or expansion clip to assemble. You drive it with a socket or impact wrench on the hex head, and it can be backed out if you need to reposition.

The galvanized coating on this carbon steel anchor is intended for damp and exterior-exposed work such as covered outdoor equipment pads, strut and conduit racks, and standoff brackets. For continuous moisture, coastal salt exposure, or submerged conditions, a stainless anchor is the better call since galvanized carbon steel will eventually corrode in those settings.

The 5 inch figure is the overall anchor length, so your usable thread is 5 inches minus whatever embedment your concrete anchoring requires. Measure the combined thickness of the plate, shims, and any grout bed first, then confirm the remaining length gives you the embedment the manufacturer calls for on a 5/8 inch screw anchor. Thick base plates are the common reason a 5 inch anchor comes up short.

No. It's a hex head screw anchor, so the head bears directly on the fixture and there is no nut or washer in the box, just 10 anchors. If your bracket has oversized or slotted holes, order structural washers separately.
