PCT No. PCT/US91/04688 Sec. 371 Date Jan. 6, 1993 Sec. 102(e) Date Jan. 6, 1993 PCT Filed Jul. 1, 1991 PCT Pub. No. WO92/01213 PCT Pub. Date Jan. 23, 1992.A tightening fixture for tightening a lock nut on a chuck including a torque readout device for measuring the torque applied to tighten the lock nut. The tightening fixture includes a stationary support block having a torque transmitting collar rotatively mounted therein. The torque transmitting collar is designed to receive and hold the chuck so that the chuck is held nonrotatable with respect to the collar. When torque is applied to tighten the lock nut on the chuck, the chuck and collar rotate as a unit. A torque indicator is mounted in the stationary block and is responsive to the rotation of the torque transmitting collar to provide an indication of the torque applied to tighten the lock nut.
