Metallics JNA143 – Frequently Asked Questions
1) Can I use the Metallics JNA143 anchor to fasten conduit straps and boxes to concrete block?
Yes, that's the normal use. A 1/4 x 3 hammer-drive nail-in anchor is what electricians reach for to hang strut, conduit straps, device boxes and panel backing on concrete, block and brick. Drill through the mounting hole of the fixture into the base material, insert the anchor, and drive the pin. No torquing, no setting tool.
2) Are Metallics JNA143 nail-in anchors rated for outdoor or damp locations?
These are steel with a zinc plating, which is a mild indoor or protected corrosion finish. For dry interior concrete and block work they're fine. For exterior exposure, wet locations or coastal air, use a stainless or hot-dip galvanized anchor instead, because zinc plating will rust out.
3) Can a hammer nail-in anchor be removed or reused later?
No. The JNA143 is a one-shot drive anchor: the pin expands the body permanently when you hammer it home. If the fixture has to come off and go back on, or you need to adjust position later, use a threaded anchor such as a sleeve or wedge anchor with a nut instead. Removing a nail-in usually means cutting the head or drilling it out.
4) How many anchors come in a Metallics JNA143 pack?
They ship 100 pieces to a jar. The jar pack is the usual way these move for truck stock, so one unit covers a typical day of strap and box mounting without reordering.
5) What is the manufacturer part number for the Metallics 1/4 x 3 nail-in anchor?
Order it as Metallics JNA143. That's the 1/4 inch by 3 inch zinc-plated steel hammer nail-in anchor, packed 100 to a jar.
