Metallics TS3410D Anchors 3/4 x 10 Wdg St-zn (Box 10)

A 3/4 inch wedge anchor like the TS3410D goes into a 3/4 inch diameter hole, drilled with a carbide-tipped bit to ANSI hammer-drill tolerances. The anchor diameter and the bit diameter are the same number on wedge anchors, which trips up people used to sleeve or screw anchors. Drill deeper than your intended embedment so drilling dust has somewhere to go, blow the hole clean, then drive the anchor and tighten the nut to expand the clip against the concrete.

Wedge anchors such as the TS3410D are intended for solid, poured concrete. They rely on a steel expansion clip biting into a clean cylindrical hole, so hollow block, brick, mortar joints, and grouted CMU will not develop reliable holding values. For hollow masonry, use a sleeve anchor or a screen-tube and adhesive system instead.

No. On a 3/4 x 10 anchor, the 10 inch figure is the overall length of the anchor, not embedment. Part of that length sits above the surface to pass through whatever you are fastening plus the washer and nut. The long body exists so you can anchor through thick material, grout beds, base plates, or standoff shims, while still getting the expansion clip deep into sound concrete.

The TS3410D is zinc plated carbon steel, which is a dry-interior finish. It is fine for mechanical rooms, equipment pads under roof, strut and conduit racks, and general interior structural attachment. For exterior exposure, wash-down areas, pool rooms, coastal sites, or anywhere treated lumber contacts the anchor, specify a stainless or hot-dip galvanized wedge anchor instead.

Yes. Wedge anchors are supplied as a complete assembly with the expansion clip, a flat washer, and a hex nut already on the threaded end, so nothing extra is needed to set them. The TS3410D is sold 10 anchors to a box.

No. Once the nut is tightened and the clip expands, a wedge anchor is permanent. You can back the nut off and remove whatever was fastened, but the anchor body stays in the concrete. The usual fix is to drive the stud flush below the surface and patch, then set a new anchor nearby. If you need an attachment you can take apart and reset, use a drop-in anchor with a threaded insert and a separate bolt.

They come 10 anchors per box. That is the pack, so quantity one gets you 10 anchors, not a single piece. For a layout like an equipment pad with four hold-downs at each of several frames, work out your total piece count and round up to whole boxes.
