These are possibly the largest caster wheels i've ever seen. They are durable, easy to install, and work great! The only downside is that there is no locking mechanism, but i should have taken that into consideration on purchase.

These heavy-duty wheels are silky smooth and allow me to easily move my workbench around my garage. Easy to install, roll perfectly smooth on our facility's painted concrete floors (we use these indoors); they carry 200+ lbs.

Worked great for a mobile work cart. Nice, sturdy caster wheels. Came with screws and screwdriver. My cart is now 10 times more useful.

The bolt pattern is 73mm center to center length wise. The holes are elongated, so plus or minus 3mm. Fit like a glove on my craftsman toolbox.

They swivel and roll with absolute ease, are constructed solidly, and lock with authority. Brakes hold securely in place. They roll smooth, lock down tight and don't budge.

Whatever bearing they used for the plate feels crunchy. Didn't hold up.
