Metallics DIA38CB – Frequently Asked Questions
1) What thread size do the Metallics DIA38CB drop-in anchors take?
The DIA38CB drop-in anchor is internally threaded 3/8-16, so it accepts a 3/8 inch bolt or threaded rod with standard 16 threads per inch coarse thread. You thread the bolt or rod straight into the anchor after it is set in the concrete, which is why these are used for hanging strut, trapeze supports, and rod-hung conduit or fixtures where the fastener may need to come back out later.
2) Do I need a setting tool to install a 3/8 drop-in anchor?
Yes. A drop-in anchor like the DIA38CB is set by driving an internal expander plug with a matching setting punch after the anchor is dropped into the drilled hole, flush with the concrete surface. The setting tool is a separate item and is not part of the 250 piece box, so order one with the anchors if you do not already have the 3/8 size on the truck.
3) How many anchors come in a box of Metallics DIA38CB?
They ship 250 anchors to a box, packaged as a box rather than loose or bagged. That quantity suits a full overhead hanging run, so an electrical contractor laying out trapeze hangers or rod drops across a floor is not reordering mid-job.
4) Are these drop-in anchors corrosion protected for indoor overhead use?
The DIA38CB is steel with a zinc finish, which is the normal protection level for dry interior work such as conduit hangers, strut, and equipment mounted to concrete decks or slabs. Zinc plated steel is not intended for wet, exterior, or corrosive exposure; for those conditions specify a stainless or hot dip galvanized anchor instead.
5) Should I use a drop-in anchor or a wedge anchor for hanging conduit from a concrete ceiling?
Use the drop-in style, like the DIA38CB, when you want the anchor flush in the slab and a removable 3/8 inch bolt or threaded rod going into it. A wedge anchor leaves a stud sticking out permanently and cannot be reused once set, which makes it awkward overhead and for anything you may need to take down. The trade-off is that a drop-in has to be installed in the correct depth hole and set with its punch before it will hold.
6) What is the Metallics part number for the 3/8-16 drop-in anchor?
Order it as Metallics DIA38CB. That is the manufacturer part number for the 3/8-16 zinc plated steel drop-in anchor supplied 250 to a box, and it is the number to quote when matching an existing anchor on a job already in progress.
