Review on Hillman 150006 Coarse 18 Inch 100 Pack by Steve Linquist

As described. I used vernier calipers and went through a batch of 20 to check the average diameter and they were in the right place. They should be great for weighting the toys I make, saving me 3-4 bearings for each toy. I'm planning to add some weight to see if I can add weight to the ends, but my review unit works fine and is perfectly balanced. To make sure the threads are correct I tried screwing them onto my 3D printer's lead screw and the batch I tested fitted perfectly so they seem to have excellent quality control so far. I would definitely recommend them to anyone who might need them. for a specific application.
