Boltstress

A magnetoelastic method for testing the body force of high strength bolts

In the head of high strength bolts stress proportional to the bolt force is induced. Measuring this stress by the magnetostriction method one obtains the bolt force directly, thus eliminating all the disadvantageous effects of the uncertainties that occur when applying further turning of the nut, because of the changing of the friction coefficient.
