GloEra 4 inch Swivel Caster Wheels Heavy Duty 1200 LBS Capacity with Safety Dual Caster, 4 Pack All with Brake No Noise Lockable Wheels (Include 16 pcs Screws Set)

The casters are great. I was bolting these to an outdoor bar that I can wheel in and out of the garage. I was not able to find the bolt size in the description. The bolts are a 5/16-18 bolt that has a thread length of 1". This is suitable for any application where there is a metal support frame. In my instance, I have a wood frame that I needed to bolt these through. I went with a 5/16 lag bolt to fasten the casters to the base frame.The casters have a minimal contact area on the ground which allows for easy maneuverability. They are on the upper edge of what I wanted to pay for a 4" caster but they were worth it. I have no complaints and no regrets. I did not expect the bolts to work for my application so that was not an issue. The locking mechanism is also smooth and does not require more than expected force.I am pleased with these casters and would purchase them again for other applications similar to this.

Replaced my crappy workbench caster wheels with these....what a difference - rolls around smooth as "butter". But (for us) it raised the height of our workbench quite a bit from the little caster wheels we had. So keep that in mind.It also barely fit two 2x4's put together as legs...we had to buy screws and didn't use the bolts that came with it, because it was going on the bottom of the workbench legs to roll around in the garage.

I bought these for a project I was building. Needed a trolley for a heavy patio heater. They needed to lock so it wouldn't move in the wind. Have bought several other kinds of casters that said they locked but only the wheels locked. When I got these I realized they locked in the rotational axis as well. Just bought 2 more sets for other projects. Highly recommend!

I was very excited for these wheels. I got them installed to use with my crate at dog shows. My dog is only 10 lbs, so these should have been overkill. My 65 lb daughter crawled in with the dog. That was enough to give it a flat spot on one of the wheels.

These roll a lot smoother than expected, even with a load on them.I bought 4 to mount to a table I built to put truck parts on while rebuilding it. I was able to put the entire bed (including the tailgate) from an 82 C10 on the table and roll it around like to was nothing. There is enough rubber around the wheels to make it very smooth when rolling as well.
