Securing box to concrete foundation

I had to mount an electrical box to concrete foundation in basement.

I used a 1/4" cement bit and used a vinyl plug anchor for concrete and a masonry screw.

Is that OK?

Yep , as long as you do not have a great amount of weight being supported by the box . A # 12 screw holds better than a # 10 Screw .

We call these plastic anchors .

I've never seen plastic anchors that would hold.
I would have used Tap-Con screws or lead anchors.

I have used a boat load of them . As long as the concrete or CMU block is " OK " they work fine to hold a plug or switch box .

Use the larger , # 12 , screws and put 6 or 8 in it & they are fine to hold a loadcenter on masonry walls .

If in doubt , hammer 2 plastic anchors in a deeper hole & use longer screws .

But , you are right , for heavier loads , Tap-Cons are stronger & really go in quick on CMU block .

Lead anchors are dinosaurs . We use steel drop-in anchors , where needed . Usually where the load is pulling straight down ( opposed to at 90 degree angle ) . Like hanging all thread rod from a concrete deck .

God bless
