Metallics TS7810 Anchors 7/8 x 10 Wdg St-zn (Box 5)

The TS7810 is a 7/8 inch diameter wedge anchor, so it goes into a 7/8 inch hole drilled with a carbide hammer bit. Wedge anchors are sized so the anchor body matches the bit diameter, and the anchor is driven through the fixture into the hole. Overall anchor length is 10 inches, so drill deeper than your embedment target to allow for drill dust.

Zinc plated carbon steel, not stainless. That makes the TS7810 suitable for dry interior concrete work, machine room floors, equipment pads and indoor structural attachments. For exterior, wet or corrosive locations you want a stainless wedge anchor instead, since zinc plating is a sacrificial coating and will corrode once it is spent.

No. Wedge anchors like the TS7810 are designed for solid, poured concrete only. The expansion clip needs dense, continuous base material to grip, and hollow block or brick will crush or blow out. For block, use a sleeve anchor or a screw anchor rated for hollow masonry.

Five anchors per box. The TS7810 is packaged as a box quantity, not sold as loose singles, so order by the box when you are laying out a run of equipment pads or strut supports.

At 10 inches overall, the TS7810 leaves a long usable grip range once embedment is set, which is why this length gets specified for thick base plates, shims, grout beds, or stacked steel. Embedment comes off the bottom of the anchor, so your fixture thickness plus nut and washer has to fit in whatever length is left standing above the concrete. For thinner plates a shorter 7/8 inch anchor is the cheaper choice.

Wedge anchors of this type ship as an assembly with the expansion clip, a nut and a washer on the threaded end, which is what you tighten to set the anchor. Nothing further is required to install beyond a 7/8 inch carbide bit, a hammer drill, a hole-cleaning blowout bulb or brush, and a torque wrench to pull the clip up against the hole wall.
