ABSTRACT:
A knob-to-shaft assembly comprises a plastic knob having a cylindrical recess having a diameter corresponding to that of the outside diameter of the shaft onto which the knob is to be manually pushed. Projecting from the outside diameter of the shaft, at the forward end thereof, is an annular band comprising a series of outwardly projecting barbs created by an angled knurl which is formed on the rearward surface of an annular V-shape groove which is provided near the forward end of the shaft. Projecting slightly forwardly from the V-shape notch is a pilot portion whose outside diameter corresponds to that of the shaft.
