Metallics JTS5312SSD Anchors 5/8-11 X 3-1/2 Wedge Ancr SS(Jar 25)

It's a 5/8-11 by 3-1/2 inch stainless steel wedge anchor. Wedge anchors are drilled with a hole the same nominal diameter as the anchor, so a 5/8 inch carbide bit in concrete, drilled deeper than the embedment you need so the dust has somewhere to go. The 3-1/2 inch overall length sets how much embedment you get after you subtract the thickness of what you are fastening plus the nut and washer.

Yes, the JTS5312SSD is a stainless steel wedge anchor, which is what you want for exterior slabs, parking structures, wet mechanical rooms, pool decks and coastal work where a plated carbon steel anchor would rust and stain the concrete. For dry interior anchoring, a zinc plated wedge anchor in the same 5/8-11 x 3-1/2 size does the same mechanical job.

No. Wedge anchors expand against the wall of the hole and need solid, cured concrete to develop their hold. In hollow block, the wedge has nothing to bite into and will spin or pull. Use a screen tube with adhesive, a sleeve anchor, or a toggle rated for masonry in those bases. Grout filled block is a question for the engineer on the job, not a default yes.

25 anchors per jar, packed in a jar rather than a box. For a strut or equipment run where you are setting four anchors per base, that is six bases plus one spare out of a single jar.

Wedge anchors ship as an assembly with the nut and washer already on the threaded 5/8-11 stud, and that is what you tighten to draw the clip and set the anchor. What you do need on hand is a 5/8 inch carbide drill bit, a hammer to drive the anchor flush, a blower or brush to clean the hole, and a torque wrench if the job spec calls out an installation torque.

No. Once the clip expands against the concrete the anchor is permanent. You can back the nut off and take the fixture away, but the body stays in the slab, and the best you can do is cut or grind the stud flush. If you need something removable, use a threaded insert or a drop-in anchor with a machine bolt instead.

Plan on concrete deeper than your embedment, never a slab you can bottom out in. With 3-1/2 inches of anchor total, most of that length can end up in the hole once you subtract the fixture thickness, so a thin topping slab or a 2 inch pad is the wrong base for this size. On a thin slab, step down to a shorter 5/8 anchor or move to an adhesive anchor where the engineer allows it.

That is exactly where a 5/8-11 stainless wedge anchor earns its keep: transformer pads, switchgear and panel bases, pipe and strut supports, and generator or rooftop unit curbs anchored to concrete. Metallics catalogues it on the electrical side of the house, and the 5/8 diameter is the usual size once you move past light strut hangers into equipment that carries real weight.
