Metallics J5022SS Anchors 1/2 x 2-1/4 Hex Nut Sleeve SS (Jar 25)

The J5022SS is a 1/2 x 2-1/4 inch hex nut sleeve anchor, so the hole is drilled at 1/2 inch diameter with a carbide masonry bit. Sleeve anchors are hole-size-matched to the bolt diameter, and the drilled depth needs to exceed the 2-1/4 inch anchor length so the expander can seat and debris has somewhere to go.

Stainless construction is why you would pick the J5022SS over a plated carbon steel sleeve anchor. It is the version to use on exterior masonry, parking structures, wash-down areas, pool and coastal work, and anywhere a zinc-plated anchor would bloom rust and stain the wall.

A sleeve anchor is the one expansion anchor that works in both solid and hollow base material, because the sleeve expands along its length rather than at a single point, so it bears against the face shell of a hollow CMU. In solid concrete or brick it also works. What it is not is a drywall or hollow-metal anchor, and in badly deteriorated block a through-bolt or an adhesive anchor with a screen tube is the better call.

Work back from the 2-1/4 inch overall length. Whatever the fixture, strut, or bracket thickness is, it comes off that length, and the remainder is your embedment in the masonry. At 1/2 x 2-1/4 you have room for a thin plate or channel with usable embedment left over; mounting through a thick base plate or a layer of furring is where you move up to a longer anchor instead.

The hex nut sleeve anchor, like the J5022SS, is removable and adjustable: back the nut off and the fixture comes free, and it works in hollow block as well as solid concrete. A wedge anchor is solid-concrete only and permanent once set. For strut, panelboards, and conduit supports that may be relocated or re-shimmed, electricians usually go sleeve. For heavy static anchorage in poured concrete, wedge.

No. It is a hex nut style sleeve anchor, so the nut is part of the assembly along with the expander sleeve. All you supply is the 1/2 inch drill bit, a hammer to seat it, and a wrench to tighten the nut until the sleeve expands against the hole wall.

That is its usual job. It is sold as an electrical fastener and the 1/2 inch diameter in stainless is a common pick for strut channel, disconnects, transformers, and panel backboards on masonry. Choose the length against your fixture thickness, since 2-1/4 inches overall has to cover the fixture plus embedment.

25 anchors per jar, and the jar pack is how it ships, so plan your count in multiples of 25. For a service van that is a sensible stocking quantity for 1/2 inch stainless anchorage; for a large anchor layout on a single job, figure your anchor count first so you are not short mid-install.
