LOVIMAG Strong Magnets, 150lb+ Waterproof Strong Neodymium Cup Magnets with Screws for Wall Mounting,Rare Earth Magnet with Holes for Holding Tools Lifting, Hanging(Silver, 6 Pack)

I was building a magnetic nail finder for my garage. I just bought an $11 cutting board (12 x 18 x .75), four 1-inch fixed mini caster wheels, and a stainless steel, adjustable flag holder to attach an old broom handle. The final ingredient was the purchase of 24 of these 100LBS neodymium disc magnets. Once attached, the magnets were about 1 inch from the ground it was searching over. For experiment 1, I attached a row of six, double stacked discs to my board and had no issues picking up some very small and light materials. Then I did a row of 6 with just one disc. Still, no issue with capturing screws. With that said, there is a noticeable bump in magnetic strength when these discs are stacked. (A word of warning, I had the torque set to my drill's lowest setting and still cracked a couple of these discs during installation. The did not crumble and all of them are still serviceable for my nail finding purpose. Just be careful). For this project, I absolutely could have gotten by with 12 instead of the 24 magnets I ordered. Since I had enough to do two magnetic rows, I did.

Nice plating on these magnets keeps a clean look. Strong magnets work well at a great price too

What a difference these very strong magnets make in projects that need a powerful grip. The added screw option was another plus. I love these and the very fair price for the performance.

These are very good magnets to secure Displate metal posters to the wall. There are a few things you need to understand first though. The screws that come with the magnets are too short. They are only long enough to go through the drywall. There are two problems with that. 1) When you pull Displates off the wall the entire magnet and screw are likely to come out of the wall with the Displate. 2) When you are trying to adjust the position of the Displate, the screw will likely get loose and will pull out from the magnet which will scratch the back of your Displate (not the end of the world I don't think, but personally I'd rather not damage my Displate at all). You really need screws that will go all the way into the stud. The screw you use absolutely must have a flat head, so as not to scratch the Displate. Also that head must fit all the way into the magnet so that it is less likely to scratch the Displate. Screws size #6 seemed to do the job perfectly (#8 may work but more likely to scratch imo). The head and actual screw of the #6 size screws appear to be smaller in circumference than even the screws that come with the magnets, so they fit into the magnet hole nicely. I was unable to find 1.25 inch long #6 wood screws at the hardware store so I went with 1.5 inch long #6 wood screws and they worked nicely. I think 1 inch long screws would work well too. You just want to make sure it goes into the wood stud located behind the drywall (use a stud finder to locate the stud). Magnets are delicate, so you want to screw the magnet by hand. You just want to make sure the screw is not protruding out of the magnet but don't tighten it too much. If the magnet is not moving at all then it's definitely tight enough. I broke one of my magnets, cracking it in 3 spots. It was my own fault as I was trying to use a screw that was a bit too big and didn't want it to protrude out and I screwed a little too tight. Even though it broke, it appears to be working just fine so I left it in the wall. It appears that a single magnet is sufficiently strong to hold a Displate in place (I have one large Displate poster being held by a single one of these magnets). In general, regardless of the magnet's strength, it's best to use at least 2 magnets per Displate because if you just use 1 often times the Displate will look funny either based on how it bends or how it hangs. I recommend either a combination of at least 2 of these magnets or 1 of these magnets plus the 2 magnets that come with the Displate. Other reviews complain that the magnet currently being sold is weaker than the magnet that used to be sold. This is absolute true. These magnets are substantially weaker than the old ones. However, for the purpose of Displates, I would argue that these weaker magnets are SUPERIOR to the old magnets. Displates simply don't require all that power. These are easier to separate from one another which is nice but most importantly these are thinner than the old magnets. Having a thinner magnet is nice because it means your Displate won't protrude so far off the wall. I do feel the 95lb claim on this magnet is blatantly false and because of that I'm subtracting a star. However, large Displates are only 3lbs so a super powerful magnet is not required. If I were using my magnets to hold tools or a handgun then I would probably want something more powerful but for the purposes of Displate metal posters these are nearly perfect aside from the fact that you need to get separate #6 screws to ensure that the magnets attach to the stud rather than just the drywall.

I purchased the 100 pound size and found the screw to object design works well. Under a craft table I can place often used items such as scissor so they are off the work surface but still nearby. I will used these in my garden shed to hang my hand pruners so they are quickly accessible. The 100 lb strength offers the power to hold capacity to hold pliers, metal tape measure, shears, a hammer or other hand tool. I recommend the 100 lb size they are about 1-1/4" across and the magnet is quite strong. I use magnets often and these being a screw on allows them to be attached to many objects. I will be buying more.

Great and strong boy are they strong great magnets

Really strong magnets. Just keep in mind they’re really brittle. So don’t over tighten them when securing them with a screw. I used them to hold up a star ceiling I built.

Nice, strong magnets. They are exactly what I wanted for a wooden access panel. The magnets are holding well. I chose these because of their included screws. The recessed hole allows the screw to be flush with the surface.

Strong grip and size also comes with screws and cover.

Very Strong magnets, and appear to be quite sturdy with the outer shell, I did drop one on the garage floor and it held up fine, as anyone who has used magnets in the past know quite well if they are not usually forgiving on drop test...

Great song magnets. Used to secure rock lights to my steel fenders on a classic truck, worked great. Used 2 per light and they do not come off easily. Have yet to loose one from a pothole or driving around.

Excellents et très efficaces aussi pour localiser les madriers à travers les murs.

Très efficace pour le grosseur des aimants
