Metallics JTS6434G Anchors 3/4 x 4-3/4 Wdg HDG (Jar 20)

Yes. The JTS6434G is hot dip galvanized, which is the finish specified for exterior and damp locations where a plain zinc anchor would rust. Typical uses are strut and conduit racks on exterior walls, equipment pads, generator and transformer bases, and rooftop supports. Pair it with galvanized or stainless hardware so you are not mixing finishes at the connection.

A 3/4 inch wedge anchor like the JTS6434G is set in a 3/4 inch diameter hole drilled with a carbide bit, since wedge anchors use a nominal-size hole and the expansion clip grips the concrete wall. Drill deeper than your intended embedment so dust has somewhere to go, then drive the anchor until the threads sit at the right height for your fixture and tighten the nut to expand the clip.

Wedge anchors such as the JTS6434G are for solid, poured concrete. They work by a clip expanding against the sides of the hole, and hollow block or brick does not give that reaction, so the anchor spins or pulls. In hollow masonry use a sleeve anchor or a toggle designed for it; in the solid grouted cells or in a concrete beam or slab the wedge anchor is the right choice.

The 4-3/4 inch overall length of the JTS6434G has to cover embedment into the concrete plus the thickness of what you are fastening plus the nut and washer. With a 3/4 inch anchor you are usually embedding most of that length, so this size suits thinner attachments such as base plates, strut channel, and angle brackets. For a thicker standoff or grout bed you need a longer 3/4 inch anchor rather than this one.

Yes, wedge anchors are supplied as an assembly: the threaded stud with the expansion clip, plus a nut and washer already on the threads. You do not order those separately. What you do need on the job is a hammer drill with a 3/4 inch carbide bit, a blow-out bulb or vacuum to clear the hole, and a wrench or impact to tighten the nut.

No. Once the nut is tightened and the clip expands, the JTS6434G is permanent. You can back the nut off and drive the stud below the surface, or cut it flush and patch, but the body stays in the concrete and cannot be pulled and reused. If you need a removable connection, use an internally threaded drop-in anchor and a machine bolt instead.

Twenty pieces per jar. That is a single jar quantity of 3/4 x 4-3/4 hot dip galvanized wedge anchors, which covers five four-bolt base plates. Order multiple jars if you are setting a run of strut racks or several equipment pads.
