VEVOR Caster Wheels, 3 inch, Set of 4, 150 lbs Capacity, Threaded Stem Casters with Security Dual Locking A/B Brake, Heavy Duty Industrial Casters, No Noise Swivel Caster Wheels for Cart, Furniture

I would be using these for my gas grill that already has the holes to be able to simply put the 4 wheels on it. My question is; it has no female threaded holes to put these threaded pieces in, and I just need to make sure these would still work? Seems like there would be no problem as long as they actually fit in the existing holes on grill legs, and I have no doubt they will fit.
