The invention relates to a removable bolt assembly for fastening a toilet seat to a commode using a knob or bar handle. The knob or bar handle, pivotally mounted to the bolt, can be used to twist or clamp the bolt into engagement with a nut that is inserted through a hole in the toilet. The hole in the toilet can be circular or noncircular. Where the hole is noncircular, the nut has a corresponding noncircular geometric neck so as to prevent it from rotating in the hole. Where the hole is circular, a fastening hinge having a connecting insert can be used to prevent rotation of the nut when it is engaged with the connecting insert. In this way the bolt is directly interlocked with the nut without the use of any tool, thereby making it easy to lock and fasten the seat to the commode.
