2 PCS Guitar Strap Locks Buttons, Mushroom Style Lock Electric Locks, Mushrooms Head Button for Bass Ukulele/Black

SET INCLUDES: 2 PCS black mushroom style strap lock buttons with 2 screws and 2 felt washers for repair hobbyists refreshing electric guitar, bass or ukulele hardware. INSTALLATION GUIDE: Place the washer under the button, align at the mounting point, drive the screw into a suitable pilot hole, then check strap hole fit before use. MUSHROOM PROFILE: Flared mushroom head and recessed centre hole create a broad strap button shape for rehearsal room swaps, stage setup checks and instrument maintenance. SPARE HARDWARE: Matching black finish across buttons, screws and washers keeps a neat look in a gig bag spare kit, on a luthier bench or during quick replacement work. FIT CHECK: Strap button hardware only, not a full quick-release set; verify screw size, pilot hole, mounting point condition and strap hole fit, and avoid over-tightening.
