Metallics JTS4334 Anchors 1/2 X 3-3/4 Wedge Ancr St-zn (Jar 50)

A 1/2 inch wedge anchor is drilled with a 1/2 inch carbide bit; the anchor body matches the hole diameter and the expansion clip grips as the nut is tightened. Drill deeper than the intended embedment so cuttings have somewhere to go, and keep total embedment plus the thickness of the fixture you are fastening within the 3-3/4 inch overall length.

No. A wedge anchor works by expanding against solid material, so it belongs in poured concrete. For hollow block, brick with voids, or drywall, use a sleeve, toggle, or screen-tube style anchor instead. The JTS4334 is the solid-concrete choice at 1/2 inch by 3-3/4 inches.

Zinc plated steel is intended for dry, indoor, non-corrosive conditions. For exterior work, wet areas, or anywhere subject to washdown or chlorides, specify a stainless wedge anchor rather than the zinc plated JTS4334.

Yes. Wedge anchors ship as a complete assembly, the threaded stud with expansion clip plus the nut and washer already on the thread, so nothing extra is needed to set them beyond a 1/2 inch carbide bit, a hammer, and a wrench.

This is the size typically run for heavier overhead and wall-mounted electrical work anchored to concrete: strut and trapeze hangers, transformer and panel mounting, large raceway supports, and equipment feet. Metallics catalogues it with its electrical fastener line, and the 3-3/4 inch length gives room for embedment plus the thickness of channel or a mounting base.

No. Once a wedge anchor is driven and tightened the clip is permanently expanded in the hole. The nut can be backed off to release the fixture, but the stud stays in the concrete, it cannot be pulled and reused. Plan for that when ordering a jar of 50 against a job count.
