Metallics TS385SSD Anchors 3/8 x 5 Wdg SS (Box 50)

A 3/8 inch carbide bit. Wedge anchors are drilled with a hole the same nominal diameter as the anchor body, then the anchor is driven through the fixture into the hole. Blow or vacuum the dust out before setting, or the clip won't expand properly against the concrete.

Yes. It's a stainless steel wedge anchor, which is why you'd pick it over a plain zinc one for exterior pads, parking structures, rooftop equipment curbs, pool decks, or washdown areas where a carbon steel anchor would rust and stain the concrete.

Wedge anchors like the 3/8 x 5 TS385SSD are for solid, poured concrete only. They set by expanding a clip against the sides of the hole, so hollow block, brick, or grout-filled cell work calls for a sleeve anchor or a screen-tube and adhesive instead.

The 5 inch overall length is what you're budgeting between embedment and the thickness of what you're clamping. Subtract your embedment depth plus the nut and washer from 5 inches, and the rest is available for the base plate, strut, or channel. That length is the reason to pick this one over a shorter 3/8 anchor: it handles thicker plates and grout or topping over the slab.

Wedge anchors ship as a complete assembly, with the nut and washer already on the threaded stud, so you only need the 3/8 inch carbide bit, a hammer drill, and a wrench to torque the nut. No separate hardware to order.

Stainless gets used where the anchor is exposed or where corrosion would be a callback: exterior transformer and generator pads, rooftop unit curbs, outdoor lighting bases, and coastal or washdown environments. The 3/8 x 5 TS385SSD is catalogued on the electrical side for exactly that kind of equipment and strut anchoring, and comes 50 to a box for a multi-base job.
