Metallics TS3485SSD Anchors 3/4 x 8-1/2 Wdg SS (Box 10)

An 8-1/2 inch wedge anchor is long for most work. You want that length when you are fastening through a thick base plate, grout bed, topping slab, or stacked shims, because a wedge anchor only develops its hold once the expansion clip is well below the concrete surface. If you are bolting a thin bracket flat to a slab, most of that 8-1/2 inches is wasted and a shorter 3/4 inch wedge anchor is the better buy. Add up material thickness plus required embedment plus nut and washer, and match the anchor length to that total.

Stainless steel, yes. That is what the SS in the TS3485SSD description refers to, and it is the reason to pick this over a plated carbon steel wedge anchor for exterior slabs, rooftop equipment curbs, pool decks, parking structures, and anywhere washdown or de-icing salt reaches the fastener. For dry interior concrete a zinc-plated wedge anchor of the same 3/4 x 8-1/2 size does the same mechanical job.

Wedge anchors like the TS3485SSD are for solid concrete only. Hollow block, brick, and mortar joints can crush or blow out when the wedge expands, which is why sleeve anchors or screw anchors are the usual pick for masonry. Keep this 3/4 inch stainless anchor in poured concrete of adequate thickness and keep it away from the slab edge.

Ten per box. These 3/4 x 8-1/2 stainless wedge anchors are sold boxed, so a single purchase covers ten anchor points, which is typically two to three equipment bases or one run of structural standoff brackets. Order in box multiples when you are setting a larger pattern.
