Metallics J1415F Anchor 1/4 x 1-1/2 FH Hmmr Drv Ancr S (Jar 100)

Treat it as permanent. A hammer drive anchor like the J1415F sets when the pin is driven down through the body and expands it in the hole, and there is no head to back out with a wrench or driver. Removal means drilling it out or shearing the head. If you need to take the fixture down again later, use a removable anchor with a machine screw instead.

No. The J1415F needs solid base material, concrete, solid brick, or the solid web of a block, because it holds by expanding against the sides of the hole. Drive it into drywall or the hollow cell of a CMU and it spins free with no grip. Use a toggle or a hollow-wall anchor there instead.

Overall length is 1-1/2 inches, and whatever thickness of strap, conduit clamp, or bracket you put under the head comes off that length. Keep at least an inch of the anchor in solid base material. The FH in the part number is the flat head, which sits flush or near flush against the fixture rather than standing proud like a mushroom head, so it is the one to use where a raised head would interfere.

It ships as a jar of 100 anchors under part number J1415F, which is the way electrical and MRO crews usually buy them for conduit strap and box mounting work on masonry. One part number covers the whole jar.

Fast, permanent light-duty attachment to concrete, block, or brick. Electricians reach for the 1/4 x 1-1/2 Metallics J1415F for one-hole conduit straps, device box mounting, and small bracket work where a screw anchor would be slower to set. Drill, insert, hit it with a hammer, done. For anything carrying real load or anything that has to come back off, step up to a sleeve or wedge anchor.
