Metallics JTS303SS Anchors 3/8 X 3 Wedge Ancr SS (Jar 50)

A 3/8 inch wedge anchor is drilled with a 3/8 inch carbide bit; the anchor diameter and the bit size are the same on wedge anchors. The JTS303SS is a 3/8 x 3 inch anchor, so drill the hole deeper than the embedment you need so the clip has room to seat and any dust falls clear.

Yes, the JTS303SS is a stainless steel wedge anchor, which is why it gets specified for exterior pads, wet mechanical rooms, pool decks and coastal work where a plain carbon steel anchor would rust and stain the concrete.

Wedge anchors, including the 3/8 x 3 stainless JTS303SS, are for solid poured concrete only. In hollow CMU, brick or grouted block the expansion clip has nothing consistent to bite into, so use a sleeve anchor or a screen tube with adhesive instead.

The JTS303SS ships as a jar of 50 anchors, each 3/8 x 3 inch stainless. Each unit includes the nut and washer, so you install straight from the jar without sourcing hardware separately.

That is the common use for this one. A 3/8 x 3 inch stainless wedge anchor gives you enough length to embed in solid concrete and still leave thread for strut channel, pipe straps, trapeze hangers or an equipment base. Length is consumed by the fixture you are clamping plus the nut and washer, so thicker standoffs leave less embedment.

A wedge anchor is the choice for permanent, higher-load fixings like transformer bases, panel stands and trapeze hangers: it expands in the hole and is not meant to come back out. A concrete screw is faster and removable, better for light boxes and temporary supports. The JTS303SS is the stainless wedge version, so pick it when the fixing is permanent and exposed to moisture.

Not cleanly. Once the nut is torqued and the clip expands against the hole wall, a 3/8 inch wedge anchor stays put. You can back the nut off and remove the fixture, then cut or drive the stud below the surface and patch. If you need to take the anchor out later, specify a removable type instead.
