These Hosco 12 mm Flat Washers are handy spares for lost or damaged parts. They fit 'import' guitar parts with metric 12 mm threads made in Japan or East Asia like our Hosco barrel output jack sockets (like those commonly used on Ibanez RG guitars) and our Hosco 3 way toggle switches (like those commonly used on Epiphone Les Paul, Schecter, PRS SE etc.). The washers are mounted under nuts to prevent damage to the jack plate, scratchplate or the guitar body when tightening up the nut.
