MySit Casters Wheels, 3-Inch Threaded Stem TPR Caster 3/8"-16 x 1-1/2", Heavy Duty Thermoplastic Rubber Wheel 450lbs Load Capacity, Set of 4

These replacement casters made a huge difference in my rolling mechanics seat.It now rolls smoothly over my garage floor and doesn't get "stuck" on things like a washer or zip tie.A great up-grade for less $$$ than a replacement seat.

Perfect for adding to wire racks that didn't come with castors.

I chose the no-locks option because I found that locking wheels tend to lock by themselves and become a nuisance. the wheels are nice and roll easily. If I had to make one improvement it would be to increase the thickness of the nut in the recessed section of the caster, even though a tool is supplied it is tight to get in when mounting, also adding a couple of washers per wheel would be helpful (I was mounting these on a rolling heater and the metal they were being fastened to was not heavy gauge so I needed washers to beef it up)

So much better than original casters. Doesn’t get hung up on every little thing. Bigger than originals.You’ll need to widen the whole in the bottom bracket for each wheel and I put on a washer and some blue locktite. Worth it!3” wheels / 1 1/2” stems.

No clue how long they will last but the factory wheels on my harbor freight stool lasted about a year. I’ve had these for a few months now and they roll way better than the hobo freight ones ever did. Smooth rolling things.

Replaced the cheap casters on a HF mechanics chair, both the red squareish one and the round adjustable height chair. These are slightly taller, and roll so much easier on concrete. Install was easy, just remove the old caster wheels and install these in the same hole. The 3/8-16 stud is a perfect fit and I will be upgrading my other chairs with these. The chair gained about 1/4" overall height, so be advised if you store your chair under a workbench or table.

Put these on the front of both our oil drain tanks at the auto shop and worked perfect

i like that it moves smoothly.i used it on my mechanic stool.
