Bolt axial tension

KFG-C20 - KFG for Measuring Axial Tension of Bolts

If it is difficult to bond a strain gage to the surface of a bolt for measuring the tightening stress, these gages enable the measurement by embedding into a hole, 2 mm diameter, bored from the top head of the bolt. They are applicable to materials having a linear expansion coefficient of 11 μm/m per ºC.
