Flutesan M6 Threaded Magnets Rubber Coated, 100 Packs, Black, 1.69 Inch

I used these to put up metal shelves on the side of my refrigerator. Really strong. Supplied hardware has a nice polish on them.

Very strong magnet's. Better than expected. I use it to anchor down my 2nd gen Starlink to the bed of my truck. I've traveled down the road (75MPH) with no issues of it moving. I've been down some rather rough dirt roads as well and it may have shifted 1/2" if that. Very happy with the quality and hardware provided.

These magnets are strong, I mean REALLY strong. We will be using them to mount cameras and lights on several different farm equipment and woodworking shop power tools. I have no doubt at all that these will do the job admirably.When we got them out we accidentally stuck two of them together and had to get a screw driver to separate them.If by some tragedy we have any problems will update this review but doubtful I will need to.

Strong and well built magnet

Great quality. Super strong!!

I used these to install an RV fan on the back of an RV refrigerator. This eliminated the need to drill holes. I could move the fan around for the best fit. These hold very well.

These are much stronger than I expected. I bought them to mount backup cameras on the back of my bobcat as they are rubber coated and basically weatherproof. I used two per camera and they are extremely difficult to pull off. No issues with vibrating loose or falling off. I also used two to mount my 7" monitor to the top of the cab. Worked out great. Very happy.

I'd hoped the protective rubber layer would be durable and protect the life of these magnets as well as connective surfaces, but the rubber is flimsy and will rip after minimal use. They should hold well enough and survive my use case (holding tarps and other items to my van walls) but they are a bit over powered in a certain sense and the flimsy rubber will tear due to the strain of magnet removal, and I'm certain the magnets will rupture eventually (as most do) with minimal use and then I will replace them with common and less strong ceramic magnets.
