This is exactly what I was looking for. Finally a center hole not designed for screws but actually large enough to accommodate the pin from my secret design. I thank you for supplying these excellent magnets.

The guys at our shop appreciate how strong these magnets are

Very strong magnets. I will buy more later

The site, purchase experience, magnets, and warning label were all good. The final layer of packaging was hard to open. No notch to rip, or ziploc, or anything. Needed a knife or scissors which wasn't ideal. 4 stars!

I was working on a special project and these magnets fit the bill and the price was a bonus as well as the fast delivery. See you on my next project!
