Metallics JTS4334G Anchor 1/2 x 3-3/4 Wedge Ancr HDG (Jar 25)

Wedge anchors like the 1/2 x 3-3/4 JTS4334G are for solid, cured concrete only. In hollow block, brick, or mortar joints the expansion clip has nothing solid to bite and the anchor spins or pulls. For hollow masonry use a sleeve anchor or a toggle rated for block instead.

Hot dip galvanizing is the reason to pick this one. The zinc coating on the JTS4334G holds up in exterior and damp interior concrete work, which is where plain zinc-plated anchors rust out. Typical uses are anchoring strut, exterior conduit racks, equipment pads, and light pole or handrail bases to cured concrete.

With a 1/2 x 3-3/4 anchor the 3-3/4 inches is total length, split between embedment in the concrete and the thickness of what you are fastening plus nut and washer. Plan the embedment first, then whatever length is left is your usable clamp thickness. For thicker base plates or shims, step up to a longer 1/2 inch wedge anchor rather than shorting the embedment.

No. Once the 1/2 inch wedge anchor is driven and the nut torqued, the clip has expanded against the hole wall and the anchor stays in the concrete. You can back the nut off to free the fixture, but the stud does not come out. If you need a removable fastener, use a female anchor such as a drop-in or a threaded insert and a bolt.

Wedge anchors in this style ship as a complete assembly, the threaded stud with its expansion clip plus the nut and washer already on the bolt. Nothing separate to order to set them. The JTS4334G is packed 25 anchors to a jar.

25 anchors per jar. That is the standard pack for 1/2 inch wedge anchors and it suits a single run of strut or a handful of equipment bases rather than a full bulk job.
