Metallics TS3850SS Anchors 3/8 x 5 Wdg SS (Box 50)

Wedge anchors like this one are made for solid, poured concrete. The expansion clip needs continuous solid material to bear against, so hollow block and brick are the wrong base material. For hollow masonry use a sleeve anchor or a screw anchor rated for block instead.

Fifty anchors per box, and the box is the pack type, so you order in multiples of 50 rather than by the piece. For a strut or conduit run with four anchors per support, one box covers a dozen supports with spares.

Yes, and that is the main reason to pick the TS3850SS. Plated carbon steel wedge anchors corrode where there is standing water, chlorides, or washdown, which loosens the clamp over time. Stainless is the version to spec for exterior pads, parking structures, pool and kitchen areas, and coastal sites. Indoors and dry, the plated version does the same mechanical job for less.

TS3850SS is the Metallics part number, covering the 3/8 x 5 stainless wedge anchor sold 50 to a box. One model, so there is no finish or length choice to specify on the order.

It's an electrical-department fastener, used for anchoring to concrete: strut channel, conduit supports, panel and transformer mounting feet, cable tray hangers, and equipment pads. The 5 inch length is the one you reach for when you have a thick base plate, grout, or a layer of standoff between the fixture and the slab.

A wedge anchor of this type is supplied as the anchor body with its expansion clip and the nut and washer on the threaded end, which is what you tighten to set it. Nothing else ships with it, so the drill bit, hammer drill, and torque wrench are on you, as is any oversized or structural washer your detail calls for.
