Metallics JFSD1431 – Frequently Asked Questions
1) What size hole do I drill for the Metallics JFSD1431 split drive anchor?
The JFSD1431 is a 1/4 inch diameter split drive anchor, so it goes into a 1/4 inch hole drilled in masonry or concrete. Split drive anchors are one-piece and sized to the nominal hole, the split shank compresses as you hammer it in and springs back against the hole wall. Drill the hole deeper than the embedment you need so dust doesn't bottom the anchor out, and hammer the anchor until the flat head seats on the fixture.
2) Is a split drive anchor removable, or is it permanent once driven?
Treat it as permanent. A split drive anchor like the JFSD1431 has no nut or screw to back out, it is hammered home and the spring tension of the split shank holds it. There is nothing to loosen, and pulling one usually damages the hole. If you need to be able to take the fixture off later, use a sleeve or wedge anchor with a bolt, or a threaded insert, instead.
3) Can I use a split drive anchor in drywall or hollow block?
No. A split drive anchor needs solid base material, concrete, brick, or solid masonry, because it works by spring tension against the wall of a drilled hole. In drywall or a hollow cell it has nothing to push against and will spin or pull straight out. For hollow walls use a toggle or self-drilling drywall anchor instead.
4) How thick a fixture can a 1/4 x 3-1/2 split drive anchor hold down?
Overall length is 3-1/2 inches, and whatever thickness of strap, bracket, or conduit clamp you put under the head comes off that length. The rest is embedment into the base material. For thin electrical hardware like a one-hole strap you get close to the full 3-1/2 inches of embedment, which is why this longer version gets used where the concrete surface is soft, painted, or has a skim coat over it.
5) What does the FH on the Metallics JFSD1431 anchor mean, and will it sit flush?
FH is flat head. The head is flat on top rather than domed, so it seats low against the fixture and leaves less of a bump than a round or mushroom head. Note it is a flat head, not a countersunk head designed to sink into a chamfered hole, so it bears on the surface of whatever you are fastening down.
6) How many anchors come in the Metallics JFSD1431 jar?
Each JFSD1431 jar holds 25 of the 1/4 x 3-1/2 flat head split drive anchors. The jar pack is the standard unit for this item, so count your fastening points in multiples of 25 when you order for a conduit run or strap-out.
