Minerallac 60402J – Frequently Asked Questions

1) What size bolt goes into the Minerallac 60402J drop-in anchor?
The 60402J takes a 1/4-20 bolt. The anchor is internally threaded, 20 threads per inch, with 0.875 inch of usable thread depth. So pick your bolt length as material thickness plus washer plus about 7/8 inch of engagement, and no more, or you will bottom out in the anchor before it clamps.
2) How deep does the hole need to be for a 1/4-20 drop-in anchor in concrete?
Minimum embedment for these anchors is 1 inch, which matches the anchor's 1 inch overall length, so the hole has to be drilled at least the full length of the anchor and cleaned out so the anchor sits flush with the concrete surface. Drill a touch deeper than 1 inch to give the dust somewhere to go. Once seated, drive the included setting tool until the internal plug expands the anchor against the hole wall.
3) Will a drop-in anchor work for hanging threaded rod for conduit and pipe hangers?
Yes, and that is the common use. Because the anchor is internally threaded 1/4-20 and sits flush in the slab, you thread 1/4-20 all-thread straight up into it - no protruding stud to trim like a wedge anchor leaves. It is the usual pick for overhead trapeze and hanger work off a concrete deck. Note the 0.875 inch thread depth limits how far the rod can run in.
4) Do I need to buy a separate setting tool for these Minerallac anchors?
No. The 60402J jar ships with the setting tool. A drop-in anchor is not usable without one, so this saves buying the tool separately if it is your first run of 1/4-20 drop-ins.
5) Can I use these drop-in anchors outdoors or in a damp area?
The anchor body is steel with a zinc plated finish, which handles general interior and sheltered conditions and resists incidental moisture. Zinc plating is not the choice for continuous wet exposure, coastal air, or corrosive process areas - for those, specify a stainless anchor instead.
6) Drop-in anchor or wedge anchor - which should I use in a concrete deck?
Use a drop-in like the 60402J when you want the fastener removable and the anchor flush with the concrete: it sets into a 1 inch minimum embedment, stays below the surface, and accepts a 1/4-20 bolt or rod that can be taken out and reinstalled later. A wedge anchor is a permanent protruding stud, better when you are bolting a base plate down once and never removing it. For overhead work and anything you may need to service, the drop-in is the practical choice.
7) Can these anchors be set in block, brick, or hollow-core plank?
Drop-in anchors are rated on solid normal weight concrete - the published values here are for 2000 and 4000 psi normal weight concrete. They rely on expanding against solid material, so they are not the fastener for hollow block, brick veneer, or the voids in hollow-core plank. Use a sleeve or toggle-type anchor rated for hollow base material in those substrates.
8) How do I know the drop-in anchor is actually set?
Seat the anchor flush, then drive the setting tool with a hammer until the tool shoulder bottoms against the anchor lip and stops moving - that is the internal plug fully driven and the body expanded. A short blow that does not bottom the tool leaves the anchor loose, and it will spin or pull when you tighten the bolt. The tool comes in the jar with the 60402J.
