Metallics TS6614SS Anchors 3/4 x 6-1/4 Wdg SS (Box 10)

A 3/4 inch wedge anchor like the TS6614SS uses a 3/4 inch carbide hammer-drill bit; the hole diameter matches the anchor diameter on wedge-style anchors. Drill the hole deeper than the embedment you need so debris has somewhere to go, and blow or vacuum it clean before setting, or the wedge clip won't expand properly.

Wedge anchors, including the 3/4 x 6-1/4 TS6614SS, are for solid poured concrete. They rely on the expanding clip biting a hole wall that will not crumble, so hollow block, brick, mortar joints, and stone are the wrong base material. For masonry use a sleeve anchor or an adhesive anchor with a screen tube instead.

Stainless is the reason to pick the TS6614SS. Zinc plated carbon steel wedge anchors are fine indoors and dry, but they corrode in exterior concrete, parking structures, pool decks, coastal air, and wash-down areas. The stainless body also keeps the anchor from staining the slab around it. If you're fastening galvanized or stainless strut, pipe stands, or equipment bases outside, match the anchor material to avoid galvanic problems.

Wedge anchors in this style are supplied as a complete assembly, with the nut and washer already on the threaded stud. You install it through the fixture, then tighten the nut to set the wedge. Nothing extra to order beyond the right drill bit.

Not really. Once the TS6614SS is torqued and the clip has expanded, the body stays in the concrete. You can back the nut off and remove the fixture, but pulling the anchor is not practical, so the usual approach is to cut or grind the stud flush with the slab. If you need a removable fastening, use a threaded insert or a drop-in anchor with a machine bolt instead.

A box of 10 covers two four-hole base plates with two spares, so for a single rooftop unit curb, pipe support, or guardrail post it's the right quantity. Larger runs of bollards, racking, or multiple machine bases will need more than one box.
