Metallics LCSX3860 Anchors 3/8 x 6 Hx Hd Lg Dia CS St-Gv (Box 40)

The LCSX3860 is a 3/8 x 6 inch hex head large diameter concrete screw anchor, carbon steel with a galvanized finish, packed 40 to a box.

The galvanized carbon steel finish on the 3/8 x 6 inch LCSX3860 is the usual choice for exterior and damp interior work such as rooftop equipment curbs, parking structures, and exterior strut runs. For permanently submerged or coastal salt spray exposure, stainless is the better material.

Hex head, so it drives with a socket on an impact wrench or impact driver rather than a bit. No setting tool, no expansion sleeve, and no epoxy is involved, which is why electricians use these for strut, cable tray, and panel mounting in concrete.

The 6 inch overall length of the LCSX3860 splits between embedment in the concrete and the thickness of what you are fastening, so it is sized for thicker standoffs, sill plates, ledgers, and stacked strut or shim assemblies rather than thin bracket work. For a thin plate on concrete a shorter 3/8 inch screw anchor gets you the same hold with less drilling.

It is a large diameter concrete screw anchor, not a wedge or sleeve anchor. It threads into a drilled hole and can be removed and the hole reused in a way an expansion wedge anchor cannot, which matters for temporary bracing or equipment that gets swapped out.
