1 x 1/8 Inch Strong Neodymium Rare Earth Countersunk Ring Magnets N52 (8 Pack)

Almost too strong.

I use them to secure materials on my laser engravers metal bed.

Perfect

Magnets were perfect for what I was using them for.

The strength of magnets and thickness is important. Stronger the better.

I use these for work hanging cameras on steel beams when needed.
