Stew Mac ebony buttons are supplied with and without dots, so will be subtle,
they also offer a kit to pre cut the threads in the wood , as they don't run a wood screw thru , to put a screwdriver on,
pre cutting the threads after drilling the pilot hole , means a lot less torque is needed to install the wooden button.
it's likely super-glued to the screw..
my '22 A has the strap around the peg head, though, it's in the middle , further out than just above the nut..
