Hosco Lever Switch Mounting Screws with a domed/raised countersunk phillips head and a metric 3 mm thread for mounting Stratocaster style lever switches like our Japanese made switches or other far eastern made switches (will not fit CRL or other US imperial switches). The screws have a choice of lengths, the shorter 6 mm length is for mounting to scratchplates (like on a Fender Stratocaster) and the longer 10 mm length for mounting through the body to rear routed cavities (like on many Ibanez, Jackson, ESP, Schecter etc. guitars). Please note these are priced per single screw.
