Great for the monkey fist paracord begleri that I’ve been making with them. Definitely recommend.

I am using these to sit on the honeycomb table of a large laser cuttter. They hold materials like acrylic sheets off of the honeycomb so there is no bounce back from the beam causing scorch marks on the underside of the material. This size fits the honeycomb pattern well.

Worked very well for what I purchased for. Printing fidget spinners and these ball bearings work well for decoration and good weight in them.

These steel balls are smooth and shiny and have a nice weight. And they are round. If left on a tilted surface, they may tend to roll off.

Perfect for use in an Alzheimer’s fidget lap pad. They will stand up to the facilities use of hot temperatures when washing and drying!

If you freeze these it can be used to break down flower material for dry sifting.

My synagogue seats were falling apart, and some of these ball hinges were missing. Who knew you could buy these? All fixed. My balls are happy.

great

As described. Works great, however you may have to use a screw driver on some of the threads. Only takes once and then you can screw them in with your fingers.
