Metallics TS4234M Anchors 1/2 x 2-3/4 Wdg Zn (Box 1000)

Wedge anchors use a hole the same nominal size as the anchor, so the TS4234M takes a 1/2 inch carbide bit drilled into solid concrete. Drill the hole deeper than the embedment you need so dust can settle below the anchor, blow it clean, then drive the anchor through the fixture and tighten the nut to expand the wedge. Overall anchor length is 2-3/4 inches, so the embedment you get is 2-3/4 inches minus the thickness of whatever you are fastening plus the nut and washer stack.

No. Wedge anchors like the 1/2 x 2-3/4 TS4234M are for solid, poured concrete only. The wedge clip needs dense material to bite against, and in hollow block or brick the hole walls crush or blow out. For hollow block use a sleeve anchor or a toggle; for brick use a sleeve-type anchor sized to the unit.

The TS4234M is zinc plated carbon steel, which is a dry-interior finish. It is fine for slab-mounted equipment, strut, pipe hangers and conduit racks inside a building. For exterior pads, parking structures, pool rooms, wash-down areas or anywhere chlorides are present, specify a stainless wedge anchor instead; plated steel will corrode at the collar and lose holding value.

Yes, with room to spare. At 2-3/4 inches overall, a 1/2 inch diameter anchor set through a 1/2 inch plate plus washer and nut still leaves roughly 2 inches in the concrete. Where you have to watch it is thicker fixtures or stacked shims, and slab thickness: a 1/2 inch anchor wants concrete deeper than the embedment plus the extra hole depth for dust, so on a thin topping slab step down to a shorter anchor or move to a different fastening method.

A wedge anchor, like the Metallics 1/2 x 2-3/4, is a through-fixture anchor: you drill through the base plate into the slab, drive the anchor, and tighten the nut. Fast, but the threaded stud stays proud and the fixture has to be in position when you set it. A drop-in or internally threaded anchor sets flush in the concrete and takes a bolt afterward, so you can remove and replace the fixture without touching the anchor. Pick the wedge anchor for one-time structural attachments and the internally threaded type where equipment gets serviced or swapped.

They ship 1000 pieces to a box, packed as a box rather than a bulk pail or carded pack. That is a stocking quantity for an electrical or mechanical contractor racking conduit, strut and equipment across a whole floor, not a small job count. Nuts and washers come assembled on the anchor; the carbide bit is separate.
