Metallics JTS6614G Anchors 3/4 x 6-1/4 Wdg HDG (Jar 10)

Yes. The JTS6614G is hot dip galvanized, which is the coating specified for exterior and damp exposure, so it holds up on outdoor concrete pads, rooftop equipment curbs, and exterior wall-mounted gear far better than a plain zinc anchor.

Wedge anchors like the 3/4 x 6-1/4 JTS6614G are for solid, poured concrete. They set by expanding a clip against the hole wall, which needs dense base material. In hollow block, brick, or grouted masonry use a sleeve anchor or a screw anchor rated for masonry instead.

Ten anchors per jar. Metallics packs the 3/4 x 6-1/4 hot dip galvanized wedge anchor in a jar pack of 10, so one jar covers ten anchor points.

Length covers the thickness of whatever you are fastening plus the embedment into the concrete. At 6-1/4 inches, the JTS6614G is a long-shank anchor meant for thick base plates, standoff brackets, shims, or grout beds where a shorter anchor would not reach enough concrete below the fixture. Measure your fixture thickness, add the embedment you need, and the anchor length must cover both.

No. A wedge anchor is a one-time mechanical anchor, the clip permanently grips the hole wall. You can back off the nut and washer to pull the fixture, but the anchor body stays in the concrete. Plan for a drop-in threaded insert if you need the fastener to be removable.
