Metallics JTS3234SS Anchors 3/8 X 2-3/4 Wedge Ancr SS (Jar 100)

Wedge anchors are drilled to the nominal anchor diameter, so a 3/8 inch wedge anchor needs a 3/8 inch carbide hammer-drill bit. The JTS3234SS is 3/8 x 2-3/4 inches, so drill the hole deeper than the embedment you need, clear the dust, then drive the anchor through the fixture into the concrete and tighten the nut to expand the clip.

Yes. The JTS3234SS is a stainless steel wedge anchor, which is why it gets specified for exterior pads, rooftop equipment, parking structures, pool and wash-down areas, and coastal work where a plated carbon steel anchor would rust out. Stainless also avoids the galvanic problem of pairing a plain steel anchor with stainless strut, clamps, or equipment feet.

Wedge anchors are for solid concrete only. They expand against the wall of the drilled hole, so they are not for hollow block, brick, mortar joints, or drywall. For hollow CMU or masonry use a sleeve anchor or a toggle; for grouted solid concrete, the 3/8 x 2-3/4 stainless wedge anchor is the right call.

The 2-3/4 inch overall length has to cover the thickness of what you are bolting down, the nut and washer, plus the embedment in the concrete. Figure a 3/8 inch wedge anchor needs roughly its minimum embedment in the slab first, then whatever is left is your usable grip. On thin material like a strut channel, conduit clamp, or equipment base plate the 2-3/4 inch length works well; for thick base plates or shimmed mounts, step up to a longer 3/8 anchor.

Yes. A wedge anchor of this style ships as a complete assembly: threaded stud, expansion clip, flat washer and hex nut already on the anchor. You drive it through the fixture and tighten the supplied nut, so no separate hardware is needed to set it.

That is the common use for it. A 3/8 x 2-3/4 anchor suits strut channel, conduit clamps, pipe hangers, junction box and panel mounting into concrete walls and decks, and the stainless version is the one to use where the location is damp, exterior, or where the strut itself is stainless. For heavier seismic or equipment anchorage governed by an engineer's drawing, follow the diameter and embedment called out on the drawing.

Each jar holds 100 of the 3/8 x 2-3/4 stainless wedge anchors, supplied as a jar pack. That is a practical count for a crew setting strut, conduit racks, or equipment bases over a job, and it keeps loose anchors contained on the truck instead of spilling in a tray.
