If you happen to lose a screw or want to change out your buckle, we sell extra belt hardware at cost on our website. Please visit our extra belt hardware page.Chicago screws can work loose in time with the vibration of wearing the belt. We torque them down tight so this is rare but can happen.  We put in our shipping confirmation email to check the screws once in a while or you can glue them together with a small drop of Loctite glue or metal Super Glue.  We do not glue them so customer can remove the buckle to polish it or switch it out.
