The 3/4" (19.05mm) diameter string retainer as used on Fender basses. It provides sufficient downward angle over the nut for the D and G strings. Mounting screw included.
Pilot holes required: Installing delicate screws such as these into hard maple requires great care and accuracy. We highly recommend using a No.38 bit for the pilot hole before installing these screws. Lubricate the screw threads with cutting lubricant (also wax or a bar of soap) to reduce friction and help them thread properly.
