MySit 3-Inch Heavy-Duty Threaded Stem Caster Wheels, Set of 4 | 3/8"-16 x 1-1/2" Stem | 450lbs Capacity & TPR Rubber for Carts, Furniture, and Workbenches

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.

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.

I needed to replace the poor-quality wheels on my chair creeper, and this set fit the bill nicely!The mounting stud is tall enough to go all the way thru the 1" square tubing, and then some, which allows threads for the mounting nuts.To be honest - I didn't use the nuts provided, as I bought 4 self-locking nuts at my local hardware store.

this is a good product.

I installed these on one of my outdoor rolling chairs. They work perfectly. Very quiet.
