Review on Caster Wheels Swivel Casters Polyurethane Hardware by Thunder Ballman

I was so surprised at how tiny these wheels are. I bought them by load and design and never paid attention to how big they are. When they arrived I double checked to make sure I got what I ordered. I have made. They come with all the screws you need, 4 on each wheel to attach it to whatever you need. I used my cordless drill with the chuck set to 4 and drilled them all into pine with no problem. It also came with a short screwdriver that would work with those screws, but I didn't hand drill the 16 screws. Once installed, all of the wheels turned effortlessly and supported the weight. The ball bearing swivels were open to allow the dirt to fall out. I work in a very dirty environment (wood dust) so I expect them to touch over time. With bearings available, this should be an easy task. We'll see in a year.
