Abstract
A nut cutter for cutting through nuts that are rusted or otherwise frozen to bolts or other threaded fasteners. The working end section of the chisel-like nut cutter includes a pair of bifurcated sharpened tines. The central notch separating the bifurcated tines is shaped to facilitate cutting nuts that are relatively inaccessible using the nut cutter held either coaxially with or at an angle to the longitudinal axis of the nut.
Claims4
A nut cutter for removing nuts frozen to threaded fasteners, said nut cutter comprising:
- a. an elongated shaft defining a main body for receiving and transmitting force to a pair of tines;
- b. a pair of tines extending from said elongated shaft, said tines having end sharpened cutting edges in alignment with one another, and perpendicular to the longitudinal axis of said shaft, and
- c. a central notch extending from between said tines toward said shaft, a portion of said notch adjacent said tines having a width greater than that of said threaded fastener for extending about said threaded fastener and permitting said tines to engage the surface of said nut on opposite sides of said fastener, said notch terminating in a blunt curved section;
- said shaft having a concavely curved surface extending from said curved section, and being outwardly inclined in the direction of said shaft, the width of said surface gradually diminishing to a tapered point in the direction of the shaft for resting against said threaded fastener and for obliquely guiding said tines into said nut.

- d. said shaft having at least one outwardly surface in the direction of said shaft and having a width exceeding the diameter of said fastener, said surface extending from said curved section along the center line of said shaft at an acute angle relative to said center line for resting against said threaded fastener and for guiding said shaft and said tines into said nut as an acute angle relative to the longitudinal axis of said threaded fastener.
