Metallics JDIA38D – Frequently Asked Questions
1) What thread size does the Metallics JDIA38D drop-in anchor take?
The JDIA38D is a 3/8-16 drop-in anchor, so it accepts 3/8 inch bolts or threaded rod with standard 16 threads per inch coarse thread. That is the common size for hanging trapeze supports, strut, and threaded rod drops off a concrete deck.
2) Do I need a setting tool to install a 3/8-16 drop-in anchor?
Yes, and it isn't included. A drop-in anchor like the JDIA38D is set by driving the internal expander plug down with a matched setting punch sized for 3/8 inch drop-ins. Order the setting tool separately if you don't already have one on the truck, and plan on a carbide bit and a hammer drill for the hole.
3) How many anchors come in a jar of Metallics JDIA38D?
Fifty anchors per jar. The JDIA38D ships as a jar pack of 50, which is how most electrical and mechanical contractors buy drop-ins for a deck full of rod drops rather than counting them out one at a time.
4) Is the Metallics 3/8-16 drop-in anchor plated for corrosion resistance?
It's steel with a zinc plating. Zinc plated steel is intended for dry interior concrete work. For exposed exterior decks, parking structures, or wet areas, step up to a stainless or hot dip galvanized anchor instead of the zinc plated JDIA38D.
5) What is the advantage of a drop-in anchor over a wedge anchor for overhead rod hanging?
A drop-in sits flush with the concrete surface and leaves an internally threaded shell, so you can thread rod up into it and remove or change the rod later without touching the anchor. A wedge anchor leaves a stud sticking out permanently and can't be backed out cleanly. For overhead threaded rod drops carrying conduit, strut, or pipe, the 3/8-16 JDIA38D is the flush, removable option.
6) How do I order the exact Metallics 3/8-16 drop-in anchor by part number?
Order by MPN JDIA38D from Metallics. That single part number covers the 3/8-16 zinc plated steel drop-in anchor in the 50 count jar, and it's the only configuration that number refers to.
