MUTUACTOR 2PCS Super Powerful Neodymium Cup Magnet with 1/4''-20 Male Threaded Stud, 92lb Vertical Pull-Force Non-Shattering Magnet Base with Nut and Washer for Lighting, Camera and Other Brackets.

Great and strong!

Strong little magnets

Used to mount a paper towel rack so that it can attach vertically to the side of a steel shelf. Works well with no sliding.

Fit, form, and function of this product is perfect! I will purchase again in the future, as needed.

Very stong, hard to pull off steel item once attached. Need to slide to the edge to lift off. Perfect for holding up tools on my grill.

The product does what it says... it is difficult to move once attached. It peel the paint off my iron fencing. Currently taken off the fencing and used to hold my smaller screwdrivers. It’s overkill but it keeps up with them.

Its difficult to put into words exactly how strong these magnets hold. Out of several I've tried, these seem to be the strongest holding - nearly permanent strength but still removable.I have used these for mounting secondary HVAC transformers where I can't easily drill into the metal panel, mounting wireless thermometers to high vibration fans and equipment where it may be damaged to drill in, as well as temporary mounting of meters or other equipment to metal panels.The 1/4-20 thread makes it easy to affix small devices, lights, etc which have camera tripod 1/4-20 thread, as well as the nut/washer allowing mounting of most things with a thru-hole. I have also had a couple things where the thread was too long and I was able to cut it short with a hack-saw and worked great.

Thank you
