Metallics TS4512SSD Anchors 1/2 x 5-1/2 Wdg SS (Box 25)

A 1/2 inch wedge anchor like the TS4512SSD goes into a 1/2 inch hole drilled with a carbide hammer-drill bit. The nominal anchor diameter and the bit size are the same on wedge anchors, which is what distinguishes them from sleeve or screw anchors. Drill deeper than the embedment you need so dust and cuttings have somewhere to go.

No. Wedge anchors, including the 1/2 x 5-1/2 TS4512SSD, are for solid concrete only. The wedge clip needs solid material to expand against, so hollow CMU, brick, or grouted block calls for a sleeve anchor, a screw anchor rated for block, or an adhesive anchor with a screen tube instead.

Corrosion is the deciding factor. The TS4512SSD is stainless, so it holds up on exterior slabs, parking structures, rooftop equipment curbs, pool decks, and wash-down areas where a zinc-plated carbon steel anchor will rust and stain the concrete. For dry interior anchoring, the zinc version of the same size is the usual choice.

It can be. The 5-1/2 inch length on the TS4512SSD is meant for thicker fixtures, base plates, or stacked material, because whatever thickness you are clamping comes off the end that sits above the concrete. If you are only fastening strut or a thin bracket to a slab, a shorter 1/2 inch wedge anchor gives you the same hole diameter without excess thread sticking up past the nut.

Wedge anchors ship as a complete assembly: threaded stud, expansion clip, and a nut and washer already on the end. You tighten the supplied nut to set the anchor. Nothing else is needed beyond the correct hammer-drill bit and a way to clean the hole.

It is a concrete anchor for mounting electrical equipment to slabs, walls, and decks: transformer and panel base plates, generator and rooftop unit frames, strut and trapeze hangers, and conduit rack bases. The 1/2 inch diameter puts it in the range used for heavier supported loads rather than light device boxes.

No. Once the TS4512SSD is driven and the nut is torqued, the clip has expanded against the concrete and the anchor is permanent. You can back off the nut and remove the fixture, but the stud stays. If you need the anchor gone, cut or drive it below the surface and patch. Jobs that need a removable fixing call for a threaded insert or drop-in anchor instead.

Yes, pairing matters. Because the TS4512SSD is stainless, keep the nut, washer, and the fixture it bolts through in compatible material where moisture is present. Running a stainless anchor through a plain carbon steel plate in a wet location invites galvanic corrosion at the contact point, so match hardware or isolate it.
