Do these magnets have to be installed or screwed in somewhere?

No, they're magnetic. I stick them on the refrigerator and metal cabinets in the garage, they're even strong enough to stick to the sheet metal used to reinforce drywall corners even though I pretty much use them to hang keys, hats, and other fairly light stuff. And they don't have a hole through which you could put a screw.

Sorry, I don't know the answer to that. Mine was a custom installation where I had to glue them in place.

Yes, they have a magnet that holds them in place but it's not extremely strong.

I put them on my kitchen cabinets and drawers for a remodel. I had them put on by the contractor and don't recall him having to get different screws.

No screws needed but just make sure they are the right length, they were too long for my 2008 gmc envoy

As with all the other responses, mine are installed vertically. Since they mount in from the back side, you'll be able to spin them 360-degrees from the front and align their position before you tighten them down (again from the back).

i am not sure, but they are steel and should adhere. i don't use a magnet rack.

Yes, they will. I bought the magnets for a similar project and they work well.

You just push them in...start with the "positive" end...from what I remember it's sort of tight but you CAN get them installed!

You need to attach them with provided screws so they don't fall off. I did the same thing at first

We have affixed them with double sided tape (I believe the tape was included but I'm not certain) but they also come with screws in case you want to mount them that way. They work great.

No. They are installed with four screws. All you need is a Phillips screwdriver.

Yes. They screw into pre-drilled holes. They must be attached by the purchaser.

The magnets are drawn to the nail heads that attach the drywall to the studs. Usually those are close to center on the stud. I've never had an issue missing a stud.

Yes, they screw into place. Best (easier) to keep an existing unit on the floor and buy & stack another unit atop of the existing one - which is what I did.

You need to attach them yourself. Also, the magnets say "TAPE SIDE" but there is no tape. You are supposed to use the four two-faced tape squares; attach the tape to the magnets, then attach the magnets the board. NOTE: You will need to use ALL four magnets, they are VERY weak and two magnets will NOT support this board.

Mine are not magnetic either. If I were attaching to metal I would use either velcro tape, or double sided tape. The lights are very light, so I think either would work.
