(25 Pieces) PGN - 1/2 Inch (0.5) Precision Chrome Steel Bearing Balls G25

We use them in our after school program to test the viability of our engineering projects.

Stainless? See the photo of what happens when these got wet ... Nit what I expected or what stainless usually means.

Two thumbs up and five stars (easily).. These are very well made and look and work great... If I need more of these at this size I know where to get them now. Good day & God Bless... Randall M. Rueff K9RMR

Just sand down a bit the hole where the ball goes in the cylinder, fairly easy.
