Metallics JTS4414316SS Anchors 1/2 X 4-1/4 Wedge Ancr SS (Jar 25)

A 1/2 inch wedge anchor is set in a 1/2 inch hole drilled with a carbide bit, hammer-drilled into solid concrete. The anchor body matches the bit size, so you drill the hole deeper than the embedment you need, clean the dust out, drive the anchor through the fixture, then tighten the nut to expand the clip against the hole wall.

No. Wedge anchors like the 1/2 x 4-1/4 Metallics are for solid, poured concrete only. The expansion clip needs dense, uniform material to grip, and hollow block, mortar joints or brick will blow out. For block, use a sleeve anchor or a screw anchor rated for masonry instead.

The JTS4414316SS is the stainless steel version, which is what you want for exterior, wet, washdown or coastal work where a zinc-plated carbon steel anchor will rust at the threads and seize the nut. Typical uses are rooftop equipment curbs, exterior strut and conduit supports, pool and kitchen areas, and anything in a chemically aggressive plant environment. Indoors and dry, plated carbon steel is normally enough.

Yes. A wedge anchor of this type ships as a complete assembly, the stud with the expansion clip plus a hex nut and washer already threaded on, which is what lets you drive it through the fixture and tighten in one step. Nothing else is needed beyond the correct carbide bit and a hammer drill.
