Metallics JFSD144 – Frequently Asked Questions
1) What size hole do I drill for the Metallics JFSD144 split drive anchor?
The JFSD144 is a 1/4 inch diameter split drive anchor, so it goes into a 1/4 inch hole drilled with a carbide masonry bit. Split drive anchors are sized to the nominal anchor diameter, with no expansion sleeve or setting tool involved, and the hole should be drilled deeper than the embedment you want so dust has somewhere to go. At 4 inches overall length, drill accordingly for the thickness of the fixture you are fastening plus your embedment into the concrete or block.
2) Is the JFSD144 anchor removable or is it permanent once driven?
Treat it as permanent. A split drive anchor is hammered home and the compressed split shank bites the hole wall, so there is no nut or screw to back out. Removing one usually means cutting or grinding the head flush. If you need to be able to take the fixture off later, use a machine screw anchor or a sleeve anchor with a threaded fastener instead.
3) What head style does the Metallics JFSD144 have, and will it sit flush?
It is a flat head (FH) split drive anchor. The flat head is meant to seat down against the fixture or, in a countersunk hole, close to flush, which suits strap, conduit clip, and bracket fastening where a round or mushroom head would stand proud. Driven into a plain untapered hole the head will still sit on top of the material rather than fully sunk.
4) Are these anchors corrosion protected, and can I use them outdoors?
The JFSD144 is steel with a zinc finish (St-Z). Zinc plating handles dry interior work and damp conditions reasonably, which covers most conduit, strap, and bracket anchoring on a building. For permanently wet, coastal, or chemically aggressive exposure, specify a stainless or hot-dip galvanized anchor rather than zinc plated steel.
5) How many anchors come in a Metallics JFSD144 jar?
Each JFSD144 jar holds 25 of the 1/4 x 4 inch flat head split drive anchors. The jar pack is the ordering unit, so quantity 1 gets you 25 pieces, which is the practical size for electrical rough-in and strap work rather than a bulk box.
6) What is a split drive anchor normally used for on electrical work?
It is the quick one-piece masonry fastener electricians reach for when anchoring conduit straps, pipe clips, box brackets, and small supports to concrete or solid brick. Drill, set the fixture, drive the anchor with a hammer, done, no setting tool and no threaded fastener to assemble. The 1/4 x 4 inch size gives enough length to pass through a fixture and still get meaningful embedment.
