CMS magnetics Powerful Cup Magnets 100 LB Pull Power Mounting Magnets in Large 3.2" Diameter w/Countersunk Hole Pot Magnets RB80 3 Pieces

We bought these to hold our calendar to our fridge. I caught my finger under one as I was changing months and ended up with quite a bruise. These ARE strong. Which is what we wanted. Just be mindful when you are using them. I wouldn't let children use them.

Strong magnets but too thin for the factory mounting bolts on any led light bar or worklight. The magnets are only about a half inch thick so the bolts all stick out the back.

The picture view varies, one shows five magnets, another four, another two, the description says one pack. I received one, another customer says that they received five, apparently the number depends on who might be making the shipment and how the might feel.

Good strong magnets. I mounted these on a small dc heater from harbor freight to use as a window defroster on my jeep cj3a.

very strong will hold about anything you want
