A knob assembly for drawers and the like comprises an integral knob having a flat base member, a longitudinally-extending stem connected at one end to the base member and a threaded bore opening in a second stem end for receiving a screw fastener therein. An insert piece having a top portion and a recessed shoulder portion extending around the perimeter of the top portion is received by a collar having a central opening size to receive the top portion of the insert while blocking the passage of the shoulder portion of the insert therethrough. The collar is adapted to be crimped so as to securely engage the base member by its periphery.
