Metallics JNA1415 Anchors 1/4X 1-1/2 Hmmr Nail-In Ancr S (Jar 100), 100 Pack

That is the normal use for it. The JNA1415 is a 1/4 inch by 1-1/2 inch nail-in anchor sold through electrical supply for fastening straps, clips, boxes and brackets to concrete and masonry. Drill, hold the strap in place, drive the pin. No threading, no setting tool, and it is much faster than a screw anchor when you have dozens of straps to hang.

Pick the nail-in when the fastening is permanent and you want speed, like runs of conduit strap or ceiling clips. Drive it once and it stays. Choose a screw anchor or a sleeve anchor instead if the item ever has to come back off, or if you need to re-tighten it later, because a driven pin is not meant to be backed out. The JNA1415 at 1/4 by 1-1/2 inches is the light-duty, high-volume option, not a bracket anchor for heavy loads.

At 1-1/2 inches total length, the anchor gives up part of its length to the thickness of whatever you are fastening, so the remainder is what sits in the base material. A thin steel strap leaves most of the anchor in the hole. If you are going through something thick, like a wood blocking or a stacked bracket, step up to a longer nail-in so you keep enough length in the concrete or block.

One hundred anchors per jar. The pack is a jar rather than a box, which is what you want on a cart or a service van where you are grabbing a handful at a time for strap and clamp work.

Metallics part number JNA1415, a 1/4 inch by 1-1/2 inch hammer-drive nail-in anchor supplied 100 to a jar. That single number covers the size and the pack, so there is nothing else to specify when ordering.
