14:1 brass gearing

Independent shopping perspective
Built for mandolin replacement work, these chrome Sta-Tite 304 machines combine brass 14:1 gearing with stamped, engraved plates and round metal buttons. The ratio is intended to give you precise tuning adjustment, while the 25/64-inch post hole and 23.2 mm overall post length provide the measurements needed when matching an existing set. Their lightweight construction keeps the focus on a traditional-looking hardware update rather than adding unnecessary bulk.
