ABSTRACT:
A bolt assembly includes a knob having an aperture formed in a hub. The hub includes three ears extended radially outward. A bolt is engaged in the aperture and includes a head engaged in the hub. A cap includes three flanges extended radially inward for engaging with the ears so as to secure the cap to the knob. A spring is engaged between the cap and the head of the bolt for biasing the head of the bolt to engage with the hub. The knob and the bolt may be easily changed when the cap is disengaged from the hub. An element is engaged in the hub for engaging with a smaller bolt.
