3/8 inch, coarse thread (16 threads per inch)
Yes, they make all the difference in the world. Of course they will roll easier on a hard surface, wood or concrete for example. That said, if you aren’t overloaded ( more than 600lbs) you’ll be fine. These casters have been awesome and still going strong multiple years later.
You can find the similar caster with 3/8" thread to fit your Wire Shelving Unit.
wanted to make two units out of one kit so i will have two carts. used the casters in the inserts but need more inserts for the second set of posts. Can not find them anywhere.
We purchased two sets of the wheels after not being able to find them in store. We got the SKU found them quickly online and ordered. Shipping was reasonable and we got them within the estimated time. Very pleased with the purchase and experience.
I purchased them for a bakers rack i bought & they just screwed on at the bottom of rack so I didn't need nuts & bolts
Yes it fits the HDX 3 shelf system.
If you can pull one end or the other that may help.
No, they screw into the metal bakers rack
