Metallics TS4812SSD Anchors 1/2 x 8-1/2 Wdg SS (Box 25)

Wedge anchors like the TS4812SSD are designed for solid, poured concrete. The expansion clip needs dense, uniform material to bite into, so hollow block, brick, and mortar joints are the wrong base material, the anchor can spin, pull, or blow out the face. For hollow masonry use a sleeve anchor or a screw anchor rated for that base material instead.

A 1/2 inch wedge anchor such as the TS4812SSD uses a 1/2 inch carbide hammer-drill bit, the anchor diameter and the hole diameter are the same on this type. Drill deeper than your intended embedment so debris has somewhere to go, blow the hole clean, then drive the anchor through the fixture until the clip is fully in the concrete before tightening the nut.

25 anchors per box. They ship as a box pack, so a single order quantity gets you 25 of the 1/2 x 8-1/2 stainless wedge anchors rather than a loose count.

It depends on how much material you are going through. A wedge anchor only develops its hold from the portion embedded in the concrete, so the 8-1/2 inch length on the TS4812SSD is meant for cases where you have substantial thickness to clear first, think thick base plates, grout beds, topping slabs, insulation, or stacked steel. For a thin bracket bolted straight to a slab, that extra length just sits proud of the nut and you would be better off with a shorter 1/2 inch wedge anchor.

Corrosion. The TS4812SSD is stainless, which is what you want for exterior slabs, parking structures, rooftops, pool decks, wash-down areas, coastal sites, and anywhere the anchor sees standing water or chlorides. Zinc plated carbon steel anchors are fine for dry interior concrete but will rust and lose section in wet or treated environments.

That is the intended use. Metallics catalogs the TS4812SSD on the electrical side of the house as a fastener anchor, and a 1/2 inch stainless wedge anchor is the common choice for hanging trapeze and strut racks, transformer and panel bases, and equipment pads on poured concrete. The 8-1/2 inch length suits deep standoffs or thick mounting assemblies.

Wedge anchors of this type are supplied as a complete assembly, the threaded stud with the expansion clip, nut, and washer already on it, so you drive it and tighten the nut. Nothing separate is needed to set the TS4812SSD beyond a correctly sized carbide bit and a wrench.
