Metallics JDIA34 – Frequently Asked Questions
1) What size bolt does the Metallics JDIA34 drop-in anchor take?
The JDIA34 is a 3/4-10 drop-in anchor, so it accepts a 3/4 inch bolt or threaded rod with standard 10 threads per inch coarse thread. The anchor body is internally threaded, which means the bolt threads into the anchor rather than through it, and the anchor stays flush with the concrete surface.
2) Do I need a setting tool to install a 3/4 inch drop-in anchor?
Yes. A drop-in anchor like the JDIA34 is installed by drilling the hole in cured concrete, cleaning it out, dropping the anchor in flush, then driving the internal expander plug with a matching setting tool until it bottoms out. The setting tool is sized to the anchor diameter, so a 3/4 inch drop-in needs the 3/4 inch tool, and it is not supplied with the anchors.
3) Can I use a drop-in anchor in hollow block or drywall?
No. A drop-in anchor only works in solid base material, which in practice means cured poured concrete. It expands against the wall of the drilled hole, so hollow CMU cells, brick voids, and drywall give it nothing to grip. For hollow block use a sleeve or toggle type anchor, and for drywall use a toggle.
4) How many anchors come in the Metallics JDIA34 package?
25 anchors per jar. For electricians and contractors hanging strut, trapeze supports, or heavy equipment off a slab, that is a job-lot quantity rather than a bulk box, so size your order to the number of hanger points on the drawing.
5) Is the JDIA34 anchor corrosion protected for damp areas?
The JDIA34 is steel with a zinc plating. Zinc plate handles dry interior and normally dry concealed locations. For exterior exposure, wet process areas, or anywhere chlorides are present, specify a hot dip galvanized or stainless anchor instead.
6) Why choose a drop-in anchor instead of a wedge anchor for overhead conduit and strut?
Two reasons. A drop-in sets flush and is fully threaded internally, so the bolt or rod can be removed and reinstalled later without disturbing the anchor, which matters for overhead strut, trapeze hangers, and equipment that gets serviced. A wedge anchor is a one-shot stud that sticks out of the concrete and cannot be backed out cleanly. The JDIA34 gives you a 3/4-10 internal thread for 3/4 inch rod drops.
7) What is the Metallics part number for the 3/4 inch zinc drop-in anchor?
Order it as Metallics JDIA34. That number covers the 3/4-10 zinc plated steel drop-in anchor supplied 25 to a jar, and it is the manufacturer part number to quote on a distributor order.
