PCT No. PCT/FR92/01192 Sec. 371 Date Jun. 15, 1995 Sec. 102(e) Date Jun. 15, 1995 PCT Filed Dec. 16, 1992 PCT Pub. No. WO94/13437 PCT Pub. Date Jun. 23, 1994The tensile or compressive stress in a threaded member is determined by subtracting an unscrewing torque from a screwing torque, and dividing the resulting torque difference by a coefficient proportional to the screw pitch of the member. The torque values are recorded either statically at the screwing and unscrewing rest limit, or dynamically in a series of corresponding screwing and unscrewing positions. The method is particularly useful for measuring, monitoring and controlling stress in threaded fastening members used in screwed joints.
