CoolYeah 3 inch Stem Casters, M12*30mm 1/2" -13 x 1-1/5" Threaded, Premium Heavy Duty Replacement Wheels for Utility Carts, Shelving, Garage Work Benches etc. (Pack of 8, 4 with Brake & 4 Without)

Work great, for my steeltron steel wire shelves perfectly. Good bang for buck if your doing sets of two shelves.

These casters are not only sturdy for the price they are at, but look real good. I wish they offered more colors

I put wheels on my pop up canopy. You know, the 10 x 10 kind that folds up like an umbrella and a tent had a baby. These wheels are great for it but do require a slightly larger hole. I drill out the peg hole in the legs and install the casters there. One locking caster on each end. If you lock one end and drag the opposite end away the tent pops open for the most part. It's a one person operation instead of two.These wheels are heavy duty and can roll a decent amount even on grass.

Incorrect shank diameter for my application

Pack of 8 but only got 7. Removed all items on the shelf only to find the item missing. Very frustrating

I'm using four of these on my new ~250 lb drum sanding machine and they are terrific. Strong metal body, wide polymer wheels, sturdy stem ... these have it all. Super heavy duty and I expect them to last a lifetime.The brake function is highly effective as well. A great value for sure.

I have everything on wheels in my garage. Few years now no issues

These worked out perfect to fit our commercial ice machine bin. The threads were the same as it previous legs. Now I can easily move this around on the concrete patio for maintenance and cleaning. We have a 500lb capacity bin, so with the head unit, the bin weight and ice weight it can weigh around 700 lbs. These roll and swivel smoothly, and toe brakes set very well, you won't be unlocing them in flip flops. These work just as described and claimed, and believe we won't have to replace them for a decade or so, and only because they will be exposed to constant and sunshine.Hopefully this was helpful, Thank you!
