MUTUACTOR 74LBS Strong Magnet 1/4-20 Female Thread,2Pack Neodymium Magnet Heavy Duty for Hanging,Anti-Broken Magnetic Mounts Rare Earth Magnets for Fridge Pegboard Lighting Garage Camera Equipment

The media could not be loaded. Excellent magnets, they’re quite strong, be sure to watch your fingers for your safety. I used two of these magnets to hold a portable dust collection hose that’s about 20’ long and 3” diameter. Does just dandily. See video. Great value.My only complaint is a huge pet peeve, I ordered a 1/4-20 thread pitch which would typically take a 7/16” wrench to tighten the nuts… guess what they were… metric. Imagine my surprise and frustration when I got to the third floor of steps and found out that the 7/16” wrench I had with me, was NOT the correct size and had to waste a bunch of time and steps to go get a metric wrench from the shop, for something that was indeed threaded as 1/4-20. What an oxymoron to combine both SAE with Metric. Haha

I got these to mount a relay on my truck's valve cover. So strong I'm sure it will never come loose! They will work great to mount stuff to metal where you either don't want to drill or weld a bolt. Just be sure to test weight for your use case. I used the second one to put a screw driver rack on my tool chest.

I bought this to mount a Blink Security Camera in the Weatherproof housing. The threads are the same and all I did was to cut down the threads on the magnet. I wanted it so I could remove it after I hitch up my utility trailer with a quad and generators on it. But I think the magnet is so strong that it wouldn’t fall off, it might slide around a bit on ruff roads. And with the camera being wireless I could move it around within the WiFi range.

Small but strong

Two of the packs had the wrong size washers. The threaded shaft may be 1/4-20 but the nuts are 10 mm.Holding power is okay. Not worth $5 a piece.

I used it to stick a small base CB antenna to the side of my window air conditioner. It would withstand a hurricane, those magnets are no joke. Nice looking and good materials as well. 👌

worked great to hang lights in our barn on the metal beams

These are very strong!I needed them to mount a rack on a steel surface, and they are perfect for that. I could think of several uses for these, and I bought another spare pack for my next good idea.....
