A wingnut knob used for loosening and/or tightening a wingnut. The wingnut knob is placed over the outside surface of a wingnut so as to provide a larger grip surface area and to increase leverage for turning the wingnut. The wingnut knob generally includes an elongated upper knob portion and a corresponding bottom portion configured to hold a wingnut. The knob includes an inner surface and an opposed outer surface, the outer surface having a gripping portion, the inner surface having geometry configured to match the outer surface of the wingnut and a set screw extending through both the outer surface and the inner surface of the knob, the set screw configured to abut the wingnut when tightened wherein the knob is removably connected to the wingnut upon loosening of the set screw.
