Metallics JTS1034SS Anchors 1/4 X 3-1/4 Wedge Ancr SS (Jar 100)

Stainless steel, yes. That is what the SS in JTS1034SS refers to, and it is why electricians and MRO crews pick this one for exterior walls, parking decks, mechanical rooms, car washes and pool equipment pads where a plated carbon steel wedge anchor would rust at the washer and nut.

No. A wedge anchor like the JTS1034SS is for solid, poured concrete only. In hollow block, brick or the mortar joint the expansion clip has nothing solid to bite into and the anchor will spin or pull. Use a sleeve anchor or a screw anchor rated for masonry there, and a toggle or self-drilling anchor in drywall.

Drill a 1/4 inch hole through the fixture into the concrete, clean the dust out, then drive the anchor through the fixture until the nut and washer sit against it. Tighten the nut to draw the cone into the expansion clip. The anchor sets as you torque it, so it has to go into a clean hole, and it is not removable once set, only cut or recessed below the surface.

Yes, that is the usual job for this one. The JTS1034SS runs 1/4 by 3-1/4 inches, so after you pass through strut, a channel nut or a strap and a washer, there is still plenty of length left for embedment in solid concrete. Thicker fixtures simply eat into the embedment, so keep the total thickness of what you are fastening well under the 3-1/4 inch overall length.

One hundred anchors per jar, supplied in Metallics' jar pack. Each anchor comes as a complete assembly with its nut and washer, so a jar covers 100 fastening points without ordering hardware separately.

For a conditioned interior run, plated carbon steel wedge anchors do the job and are the common choice. Step up to the stainless JTS1034SS when the anchor sees weather, washdown, chemicals, or when it is in contact with dissimilar metals outdoors, since those are the conditions that corrode a plated anchor at the exposed thread.
