Metallics J5026SS Anchors 1/2 X 2-3/4 Slv Ancr &Nt SS (Jar 25)

Sleeve anchors are drilled at the same nominal diameter as the anchor, so the J5026SS takes a 1/2 inch carbide bit in concrete, brick, or block. Drill the hole deeper than the 2-3/4 inch anchor length so cuttings have somewhere to go, blow it clean, then set the anchor through the fixture and tighten the nut to expand the sleeve.

The 2-3/4 inch overall length has to cover both the material you are clamping and the embedment in the base material, so on a 1/2 inch anchor you are realistically fastening thin items like strut, conduit straps, or equipment feet. If you are mounting a thick plate or a shimmed base, step up to a longer sleeve anchor in the same 1/2 inch diameter rather than losing embedment depth.

Yes. The J5026SS is a stainless steel sleeve anchor supplied with a stainless nut, so the whole assembly is corrosion resistant. That is the version to use outdoors, on rooftops, in wash-down areas, or anywhere a plated carbon steel anchor would bleed rust onto a finished surface.

Sleeve anchors like the 1/2 x 2-3/4 J5026SS expand along the length of the sleeve, which is what lets them hold in hollow block and brick as well as solid concrete. Wedge anchors expand at a single point at the bottom of the hole and are solid-concrete only. If your base material is block, brick, or an unknown masonry wall, the sleeve anchor is the safer choice; if it is poured concrete and you want maximum pullout in the same diameter, a wedge anchor is the better fit.

25 anchors per jar, nuts included, packed as a jar rather than a loose bulk box. That is a single take-along quantity for a service truck, not a pallet-level buy, so a crew standardizing on 1/2 inch stainless sleeve anchors across a building will want multiple jars.

No separate hardware is needed to set the anchor. The J5026SS ships with its nut as part of the assembly, so each of the 25 pieces in the jar is complete out of the jar. All you supply is the 1/2 inch masonry bit, a hammer, and a wrench.

It is an electrical-trade masonry fastener: anchoring strut channel, conduit clamps, panel and enclosure backplates, light pole bases, and equipment feet to concrete or block. The 1/2 inch diameter puts it at the heavier end of that work, and the stainless construction is for exterior or damp locations where a zinc-plated anchor would corrode.
