Metallics LCS3470SS Anchors 3/4 X 7 Hx Hd Lg Dia CS SS (Box 10)

It is a large diameter concrete screw anchor with a hex head, so it threads directly into a drilled hole and can be driven with an impact wrench and a socket. Unlike a wedge anchor, there is no expansion clip to set, and the screw can be removed and the hole reused or patched. Choose a wedge or sleeve anchor instead if your spec calls specifically for an expansion-type anchor.

Stainless construction is the reason to take the LCS3470SS over a carbon steel anchor: exterior work, coastal sites, wash-down areas, pool decks, and anywhere the fastener head stays exposed to weather. For dry interior anchoring in conditioned space, a plated carbon steel anchor of the same 3/4 x 7 size does the same mechanical job.

Hex head, so it drives with a socket on an impact wrench, not a bit holder. At 3/4 inch diameter you want a corded or high-torque impact rather than a standard drill driver, and a matched carbide bit for the pilot hole in concrete.

Yes, it is carried as an electrical-department fastener and the 3/4 inch body suits heavy items bolted to concrete: transformer pads, switchgear and panel frames, strut and trapeze supports, generator skids. For light conduit strap and box work, a much smaller diameter anchor is the correct choice.
