Metallics TS1212SSD Anchors 1/2 x 12 Wdg SS (Box 25)

A 1/2 inch wedge anchor is set in a 1/2 inch diameter hole drilled with a carbide bit in hammer mode. The anchor diameter and the bit size match on wedge anchors, which is what lets the clip expand against the hole wall when the nut is tightened. The TS1212SSD is the 1/2 x 12 inch version, so drill deep enough to take the full embedment plus the thickness of what you are fastening, and blow or vacuum the dust out before driving the anchor.

Yes. The TS1212SSD is a stainless steel wedge anchor, so it suits exterior concrete, wash-down areas, pool decks, and coastal or chemically aggressive sites where a zinc-plated carbon steel anchor would rust and stain the slab. Stainless is also the choice when the anchor will contact treated lumber.

The 12 inch length on the TS1212SSD is for thick standoffs, heavy base plates, grout beds, topping slabs, or shimmed equipment bases, where the anchor has to pass through a lot of material before it ever reaches sound concrete. Remember that on a wedge anchor only the embedded portion carries load, so the 12 inches is overall length, not embedment. If you are bolting a plate flat to a slab, a much shorter 1/2 inch anchor is the right part and will be easier to set.

Wedge anchors like the TS1212SSD are a solid-concrete mechanical anchor, so they work in poured slabs and decks but not in hollow block, brick, or the voids of a pan deck, where you want a toggle or a sleeve anchor instead. For strut and trapeze racks the anchor also has to be set in the overhead, and the 1/2 x 12 size here is far longer than typical strut mounting needs, so it is better suited to deep embedment and thick standoff work than to a plain strut-to-deck connection.

Wedge anchors in this style ship as an assembled unit, the threaded stud with its expansion clip, plus the hex nut and washer on the thread, which you back off and reuse to tighten the anchor after driving it. No separate hardware purchase is needed to set it. You do need the matching 1/2 inch carbide bit and a hammer drill, which are not part of the box.

Twenty-five anchors per box, sold as a box quantity rather than loose pieces. For a four-bolt equipment base that is six bases per box, so size the order by total hole count rather than by job.

Order it as Metallics TS1212SSD. That number covers the 1/2 inch diameter by 12 inch stainless wedge anchor in the 25 piece box, and it is the only configuration this model number covers.
