ULIBERMAGNET 150LB 2Pack Strong Neodymium Round Magnet with M8 Female Thread, Powerful Magnetic Removable Mounting for Lighting,Tools, Equipment with Bolt

Yes, just what I wanted and needed.Strong and durable.

Fast shipping, well packaged. Nice product.

Mounting a small sensor in a waterproof box to the top of my car. So strong the box practically leaped out of my hands onto the car. Used all four but my remove two and save them for another project.

I use these to attach different finder scopes to a Newtonian telescope. I can mount any finder or device in any position I need without any slipping/sliding and they also don't scratch the ota. Extremely great hold and stability.The included screws have also been a perfect fit for every device I've tried.

Used these to hang my batteries. They are very strong and takes some good pressure to remove. Happy with purchase. Would recommend.

Fabulous, strong magnets! They have a smooth, almost soft, feel that really does not scratch. The M4 female bolt perfectly fits the bolt holes on the base of the Celestron StarSense mount so it can be moved around to any telescope with a steel optical tube.

Have to have right size to fit with cell phone. Returned for more adjustable one.

I bought these to hold an aftermarket backup camera (Yakry here on Amazon) on the tail gate of my truck to make it easier to hook up. These things are strong! Two magnets had the camera locked in place with no marring to the paint on the truck. I've even driven around to see if the camera slid down the tailgate and it does not. Really happy with these magnets. Plan on using them in other applications where I don't want to drill holes but need a solid mount.
