A rapid acting C-clamp is provided. A housing in the base of the C-clamp has a generally semi-cylindrical wall and an internal arcuate rib therein. The C-clamp has a threaded spindle extending through the housing, and a nut member in the housing is provided with a threadless bore through which the spindle extends for rapid advancement. The nut member also has a partially offset and partially threaded bore which is selectively engageable with the threaded spindle for threaded advancement of the spindle. The external surface of the nut is comprised of two semi-cylindrical portions overlapping so as to provide definite lines of demarcation between the portions. A friction member in the nut is resiliently pressed against the threads of the spindle to cause the nut to turn with the spindle in either direction. The nut cooperates with the arcuate rib, and depending on the direction of turning shifts the nut to cause the non-threaded bore to cooperate with the spindle for rapid advancement of the spindle, or to cause the partially threaded bore to cooperate with the threads of the spindle for threaded advancement of the spindle. The nut comprises a steel investment casting, while the frame of the C-clamp is forged steel, and the threaded spindle is copper coated for lubrication without the necessity of petroleum base lubricants.
