They work as advertised.
really happy with the Chicago screws I received. Quality pieces
Yep, the Chicago Screw stays tight and gets the job done.
I had to order replacement screws for my custom-sized U-lock holster (which is the most awesome thing ever, thank you). Ordering was easy; shipment was fast; S&H was fine. I would have liked the option to order replacements for the leather discs which used to cushion the screws but were lost when I lost the screws.
