Metallics JNA140 – Frequently Asked Questions
1) What size hole do I drill for the Metallics JNA140 nail-in anchor?
The JNA140 is a 1/4 inch diameter hammer-drive nail-in anchor, so it sets in a 1/4 inch hole drilled with a carbide masonry bit. Drill the hole deeper than the 3/4 inch anchor length so drill dust at the bottom does not stop the anchor from seating flush, then drive the pin home with a hammer.
2) How thick a fixture can a 1/4 x 3/4 hammer-drive anchor hold?
Not much. At 3/4 inch overall length, the 1/4 inch JNA140 is sized for thin material held tight to masonry: strap, conduit clips, one-hole straps, box mounting tabs, nameplates. Whatever thickness of fixture you stack under the head comes straight out of the embedment left in the concrete, so for anything thicker than sheet steel or a thin plastic clip step up to a longer anchor.
3) Will a nail-in drive anchor work in hollow block or drywall?
No. A hammer-drive anchor like the JNA140 expands by friction against solid material, so it needs solid concrete, brick, or solid-filled block. In a hollow block cell, drywall, or plaster it spins free with no holding value. For hollow wall work use a toggle or a self-drilling drywall anchor instead.
4) Can these anchors be removed and reused later?
Treat them as permanent. A driven nail-in anchor is a one-shot fastener: once the pin is hammered in, the body is expanded in the hole and backing it out usually destroys it. For conduit runs or equipment you expect to relocate, pick a removable threaded anchor such as a sleeve or wedge anchor with a nut.
5) What part number do I order for the 1/4 x 3/4 Metallics nail-in anchor?
Order Metallics JNA140. That number covers the 1/4 inch by 3/4 inch steel hammer nail-in anchor supplied 100 to a jar, and it is the only configuration under that model number, so there is no finish or length option to specify.
