These threaders fit snugly onto the 1" poles and the Taiwan machining is noticeably precise, no wobble or rough edges at all. I paired them with the 3" wheels and the whole shelf unit is finally stable. Took maybe five minutes to screw all four in place.

Finally, threaders that screw in without any wobble once seated on the poles. These fit my existing 1" shelving setup perfectly, and the set of four was exactly what I needed to swap out my old wheels.

The threads machined perfectly smooth on the first try, and they grabbed the poles snugly without any wobble. The set of four was exactly what I needed to convert my shelving to wheels, and the Taiwan build quality is obvious.
