These are great. So strong, difficult to part. Watch fingers or they snap back together and fingers in way will get pinched. Love them. Ordered more.

I used them on a measuring device for my lathe. Yes it worked.

Very strong magnets

I’m using these magnets to hold papers and tools etc on the framework of my forklift at work.

I've been using these magnets for years as a door catch for inset cabinet doors. One burried in the stop from behind (leaving thin wood at the front ) and one in the door (glue in thin piece of wood over it or just glue it in). It's clean and effective. Just watch your polarity when installing,you don't want to get that wrong !
