standard torque measurement techniques - giving the BG80 range accuracy within 0.0001mm (0.00001 inch). Using the gauge’s RS232 interface together with the optional shut off accessory the gauge can be programmed to automatically stop the tightening process when the appropriate load has been applied...

U.S. Pat. No. 4,333,220 with means to sense the plastic deformation and automatically halt the tightening means. U.S. Pat. No. 4,359,906 discloses a device for tightening a screw into bone and determining the applied torque to prevent overtightening of the screw and damage to the ...
The method involves measuring the torque and angle of rotation produced at time of bolt connection tightening, and calculating a gradient with a screw drop specific dynamic threshold range based on the measurements. The screw drop specific dynamic cut-off threshold, which slopes down from the gradie...
