Minerallac 60402J – Frequently Asked Questions

1) What bolt size threads into the Minerallac drop-in anchor?
It takes a 1/4-20 bolt. The anchor is internally threaded, 20 threads per inch, with 0.875 inch of usable thread depth, so your bolt only needs to pick up that much engagement plus whatever you are fastening down. Nothing threads onto the outside of the anchor, you set it flush in the concrete and bolt through your fixture into it.
2) How deep do I have to drill for these anchors?
Minimum embedment is 1 inch for the 1 inch anchor, which is the full body length, so the hole must be at least the anchor length plus clearance for dust. These are flush-set anchors, the top sits level with the concrete surface. Overhead slab work is the common use, which is why the length options stop short.
3) What lengths do the Minerallac steel drop-in anchors come in?
Two: 1 inch (part 60402J) and 1-9/16 inch (part 60404J). Both are 1/4-20 internally threaded steel. Pick the longer one where you want more embedment in the slab and the shorter where slab thickness or rebar congestion limits you.
4) Are zinc plated drop-in anchors okay outdoors or in a wet area?
Zinc plated steel is a corrosion-resistant coating meant for dry interior and sheltered work, mechanical rooms, parking structures, ceiling slabs. For standing moisture, pool rooms, coastal exposure or chemical environments, specify a stainless drop-in instead. The plating on these will eventually give up in continuous wet service.
5) Will a 1/4-20 drop-in anchor work for hanging threaded rod off a concrete deck?
Yes, that is a standard use. Set the anchor flush in the deck, then thread 1/4-20 all-thread rod straight into it for conduit, strut, or pipe hanger drops. Engagement is limited to 0.875 inch of thread, so cut and chamfer the rod end clean and run it to the bottom of the anchor.
6) Can these anchors be removed or reused if a fixture gets relocated?
The bolt comes out, the anchor does not. Once the setting tool expands the shell it is permanent in the slab. That is actually why electrical and mechanical contractors use them for threaded rod drops and strut: unbolt the hanger and the flush anchor stays put, ready to take a new bolt in the same hole.
