I used multiple 3/8" x .2" round magnets to secure a sheet of light gauge steel against a product's framework made of HDPE plastic. Once inserted using a small press, the magnets stayed in place inside a 3/8" bore without adhesive. Perfect fit for my application. The small plastic disks between each magnet made them easier to separate during project assembly.

Fast response and shipping and a great source for these powerful magnets. I have rare earth magnets from others, and the coatings are letting go and the magnets are crumbling. These are doing great.

Excellent and prompt service!
