Abstract
A two-piece knob assembly is provided for positively holding a fastener in a non-rotatable condition. The assembly includes a knob that has an aperture with varying diameters and configurations. A fastener is received in the aperture and is non-rotatably held therein due to the mating irregular configurations of the knob and the fastener. A cap is also received in the aperture to prevent the fastener from becoming dislodged in a vertical direction.
