Indeed. I've startled people who are unfamiliar with square-drive screws by
inserting a screwdriver into one of the screws in the vertical face of my
modular and letting go of it. It will hang supported only by the head of the
screw, nearly parallel to the floor.
McFeely's screws are to generic philips screws as Bourns sealed
potentiometers are to Radio Shack carbon pots.
