Metallics JTS54120SS Anchors 5/8 x 4-1/2 Wdg SS (Jar 25)

Wedge anchors use a carbide bit that matches the anchor diameter, so a 5/8 inch anchor like the JTS54120SS goes into a 5/8 inch hole drilled deeper than the embedment you need, with the dust cleared out before you set it. At 4-1/2 inches overall length, the usable embedment is that 4-1/2 inches minus whatever thickness of material you are fastening through plus the nut and washer.

Stainless is the reason to pick the JTS54120SS over a plated carbon steel wedge anchor. For exterior concrete, parking structures, pool and wash-down areas, or damp mechanical and electrical rooms, the stainless body resists the corrosion that rusts zinc-plated anchors and stains the slab. Indoors and dry, a plated anchor in the same 5/8 x 4-1/2 size does the same mechanical job for less.

No. A wedge anchor sets by expanding a clip against the sides of a fresh, correctly sized hole in solid concrete, so a reused or oversized hole will not develop its grip and hollow or mortar-jointed block will crush instead of holding. For CMU or brick use a sleeve anchor or a screw anchor rated for hollow base material; for an oversized hole in concrete, drill a new location or switch to an adhesive-anchored threaded rod.

A wedge anchor of this type ships as a complete assembly: the threaded stud with the expansion clip, plus the nut and washer already on the end, which is what you torque to set it. Nothing else is needed beyond a 5/8 inch carbide bit, a hammer drill, and a wrench.

Order it as Metallics JTS54120SS. That number covers the 5/8 by 4-1/2 inch stainless wedge anchor in the 25 count jar, so quantity is ordered in jars rather than individual pieces.
