Metallics TS32180SS Anchors 3/8 x 2-1/4 Wdg SS (Box 100)

A 3/8 inch wedge anchor is drilled with a 3/8 inch carbide bit; the anchor diameter and the bit size match on wedge anchors. Drill the hole deeper than the embedment you need so debris has somewhere to go, blow it clean, then drive the anchor and tighten the nut to expand the clip.

At 2-1/4 inches overall, the TS32180SS is a short-length 3/8 anchor. Subtract the thickness of what you are fastening plus the nut and washer, and the rest is embedment in the concrete. It suits thin fixtures, mounting plates, strut channel, and conduit straps bolted flat to slab or wall. If you are going through a thick base plate, grout, or a layer of topping, step up to a longer 3/8 anchor so you keep enough embedment in sound concrete.

No. Wedge anchors are for solid, poured concrete only. They work by wedging against the wall of a drilled hole, and hollow block, brick, or mortar joints will not take that pressure. For hollow CMU use a sleeve or toggle type anchor; for drywall or ceiling board use a toggle. Dropping a 3/8 wedge anchor into block is a common field mistake and it pulls out under load.

Stainless is the call wherever the anchor sees moisture or washdown: exterior walls, parking structures, rooftops, tunnels, pump rooms, food plants, and coastal sites. Zinc plated carbon steel anchors rust and lose clamp load in those spots. The TS32180SS is stainless through the bolt and the expansion clip, which is what matters on a fastener you can never inspect once the fixture is on it.

No separate hardware to order. A wedge anchor of this type comes assembled with its nut and washer on the threaded stud, which is how the expansion clip gets set when you torque it. You supply the drill, a 3/8 carbide bit, and a hammer to drive the anchor flush.

Yes, 3/8 is the common size for hanging strut, trapeze racks, and conduit supports from a concrete deck, and it is why the TS32180SS is stocked by the hundred. One caution on overhead work: for conduit and cable support in concrete you need an anchor accepted for that use by your inspector, and stainless matters if the deck is exposed to weather. Check the embedment you will actually achieve with the 2-1/4 inch length after the strut thickness.

Not reusable. Once the nut is torqued the clip expands permanently against the concrete, so the TS32180SS cannot be backed out and used in a new hole. If a fixture has to come off, remove the nut and leave the stud, or cut or drive the stud below the surface and patch. Order a fresh anchor for any relocation, which is the practical reason the 100 piece box makes sense on a job.
