MUTUACTOR2PCS Magnetic Base Super Powerful Neodymium Round Magnets Disc Magnets with 1/4''-20 Male Threaded Stud Magnetic Fasteners for Assembly,Vertical Magnetic Pull-Force 68KG

These are fantastic, the magnets are very strong (watch out!) and quality seems top. There's a plastic ring on the face to keep from scratching things up. Very good product.

Used these for mounting a small nebula projector onto a ceiling. I used a smaller pot magnet with the magnet switched around as the base.It's safer to unscrew the projector before trying to remove the magnet from the ceiling btw as it takes a lot of sideways force to remove.During the process of mounting to the ceiling I also discovered they these magnets make very good stud finders and picked up metal fixings through plasterboard no problem.

Used with fabricated tool holders on table. Great but if anything could be a little strong for some applications. Great for me tho.

Used for attaching solar panels to my van.Work really well. Very strong . Perfect for temporary attachment. Not for fast driving though.

No problem works perfect I used this to stick to the inside of the van for a shelf

These magnets are well strongI use them for holding my work lights up .Definitely recommend

Very good magnets,I’ve attached there to my work light to allow hands free working

Very strong magnets
