a mechanical engineer measure torque wrench tension errors? Do these bolt tension errors matter? These errors often affect an engineer's structural analysis. 4. Bolt gage. What... is an ultrasonic bolt gage? See an animated demonstration of an ultrasonic echo inside of a bolt.Mechanical engineering labs rarely have enough resources to let each engineer learn... between a one-point bolt gage and SureBolt's patented whole echo method? Are the prices similar? (Yes) 9. Engineers. Some engineers use a strain gauge to measure bolt tension...

ultrasonic bolt gages in general.(pg 403) ... As a result, we feel that the equipment is capable of residual preload measurements with an accuracy approaching +-5% in most field situations... impossible for other bolt gages due to their cupped heads and weak signals (.02 volts). But, this +- 25 lbs tension was achieved under under ideal conditions (the transducer... and resolution, not accuracy. Many manufacturers' specs only tell you how many digits their bolt gage displays. The number of digits is not accuracy and may not even be a good...
