Metallics TS385SS Anchor 3/8-16 x 5 Wedge Ancr 18-8 S/S (50 pcs)

The TS385SS is made of 18-8 stainless steel, which is the austenitic 300 series grade used for general corrosion resistance. That suits exterior concrete, damp mechanical rooms, pool decks, and parking structures where a plain zinc anchor would rust and bleed. For chloride-heavy coastal exposure, 316 is the stronger choice.

It is 3/8-16, so the stud takes a standard 3/8-16 UNC nut. The anchor ships assembled with its nut and washer. If you replace the nut, match it in 18-8 stainless to avoid galvanic mismatch with the stainless stud.

A wedge anchor like the TS385SS is for solid, poured concrete only, and it gives higher holding values than a sleeve anchor in that base. Sleeve anchors are the choice when the base is hollow block, brick, or soft masonry, where a wedge anchor's expansion clip has nothing solid to bite into and will spin or crush the material. If you are fastening into block, do not use this anchor.

No. The TS385SS sets permanently once the cone is drawn into the expansion clip. The nut can be backed off and the fixture removed, but the anchor body stays in the concrete. If it must come out, cut or drive the stud below the surface and patch. Plan layout before drilling, since a misplaced wedge anchor cannot be relocated in the same hole.

The TS385SS is packaged 50 pieces per box. For MRO stock or a repeat install like strut hangers, equipment pads, or conduit support brackets, that is one box per 50 anchor points.

It is sold as electrical-trade fastening stock, and 3/8 inch stainless wedge anchors are the common pick for securing panelboard frames, transformer and equipment pads, trapeze hangers, and strut channel to concrete walls and decks. The 3/8-16 stud accepts strut nuts and channel hardware in the same thread size.
