Set-Screw Privacy Lock Thumb-Turn Knob
A replacement thumb-turn for bathroom and closet privacy locks whose plastic turn has snapped off the spindle. A 30 mm hub has a 4.4 x 10.4 mm socket, 10 mm deep, that takes flat tail-pieces up to 10 mm wide and 4 mm thick, as well as small square spindles. An M3 set screw in a brass heat-set insert clamps whatever is there, so one part fits many lock brands without needing exact spindle dimensions. The 38 mm grip wing lines up with the blade.
