For example, if you were previously using an ISO standard, then go ahead and purchase an ISO standard threaded casters, as UTS's do not screw into ISO standard threaded tubes.Each model threaded stem caster corresponds to a different TPI, that is why users purchase new threaded rod casters that are not compatible with their old equipment.
