Metallics LCS3816SS Anchors 3/8 X 1-3/4 Hx Lg-Dia Conc Sc SS (Jar 50)

No. A concrete screw cuts its own thread in a pre-drilled hole, so there is no shield, sleeve, or setting tool involved. You drill, blow the hole clean, and drive the hex head with a socket. That makes it faster than a wedge or sleeve anchor and it can be removed and backed out if you need to relocate the fixture.

Metallics part number LCS3816SS. That one number covers the 3/8 x 1-3/4 inch stainless hex head large-diameter concrete screw in the 50-count jar, so there is no finish or pack option to specify on top of it.

Stainless is the reason to pick the LCS3816SS over a plated carbon steel screw. Exterior walls, parking structures, pool rooms, wash-down areas, and coastal jobs all chew through zinc plating; stainless is what holds up. For dry interior anchoring, a plated version of the same 3/8 x 1-3/4 screw does the same mechanical job.

Large-diameter concrete screws are driven in solid base material, so poured concrete is the primary use. Grout-filled block and solid brick also take them, but hollow block cells and soft or crumbling masonry will not develop the thread. In hollow material you want a toggle or a sleeve-type anchor instead.

That is exactly the work this 3/8 inch screw anchor is stocked for. Metallics catalogs it as electrical fastening hardware, and a 3/8 by 1-3/4 inch stainless concrete screw is the common choice for strut channel, pipe clamps, box backing, and small equipment brackets on concrete walls and decks. Heavier suspended loads generally move up to a longer screw or a through-bolted anchor.

Hex washer head, so it drives with a socket on an impact wrench or impact driver. No bit tip to cam out and no separate washer to add. Where you need a flush finish, a flat or Phillips head concrete screw is the alternative, but the hex head is what takes the torque on a 3/8 inch anchor.

Fifty per jar. For MRO stockrooms and service trucks that is a sensible standardizing quantity for one size, and the jar keeps them sorted rather than loose in a bin. Repeat conduit, strut, and equipment anchoring on a single building typically runs through a jar quickly, so buyers doing a multi-floor fit-out usually order several.
