Metallics TS508D Anchors 5/8 x 8-1/2 Wdg St-zn (Box 25)

Drill 5/8 inch. Wedge anchors use a hole the same nominal diameter as the anchor body, so the TS508D goes into a 5/8 inch carbide-bit hole in concrete, drilled deeper than the embedment you need so debris has somewhere to go. At 8-1/2 inches overall length, this one is for thick fixtures or deep embedment, not thin plate.

The TS508D is zinc plated steel, which is a coating for dry interior use and incidental moisture only. For exterior, coastal, pool, or chemically washed areas, use a stainless wedge anchor instead; plated steel will rust and lose section in those conditions.

No. Wedge anchors such as the TS508D rely on a solid, uncracked base material to expand against, so they are a poured concrete fastener. In hollow block or brick, use a sleeve anchor or a screen tube with adhesive, which spread load across the webs instead of wedging in one point.

25 per box. The TS508D ships as a box quantity, so a job needing a handful still gets the full 25, and a repeat anchor layout can be counted off in boxes.

Yes, wedge anchors ship as an assembly: threaded stud, expansion clip, and the nut and washer already on the thread. You install it as supplied, drive it through the fixture into the hole, then torque the nut to set the clip. No separate hardware to order.

It is an electrical-trade wedge anchor, so strut channel, trapeze hangers, panel backing, transformer and gear bases in poured concrete are its usual work. The 5/8 inch diameter is at the heavy end for that category, which suits equipment bases and seismic bracing more than light conduit clips. Overhead and suspended applications usually have to meet the engineer's specified anchor and embedment, so match the number called out on the drawing.

Not reusable. Once the nut is torqued the clip bites the concrete wall permanently, so the TS508D is a one-time set. The nut and washer come off, but the stud stays. If the fixture has to be demountable or moved, use an internally threaded drop-in anchor or a female insert so you can back a bolt out without pulling the anchor.

Metallics TS508D. That is the manufacturer part number for the 5/8 by 8-1/2 inch zinc plated steel wedge anchor sold 25 to a box, and it is the only configuration under that number, so there is no length or finish to specify separately.
