A single black strap button with its mounting screw, in the plain flared Fender-style shape that suits most electric guitars and basses, for replacing one that has stripped, rusted or vanished. Black finish matches black tuners and bridges, or use a pair to go from chrome to black across the whole guitar. Metal, not plastic, with a Phillips-head screw. Sold as one pin and one screw, so order two if you are doing both ends. Part number GP8476B.
