F-0408 The Coefficient of Friction of the Thread in Yielding Zone

Mitsuo KOBAYASHI, Naotake Niwa, Michihiko TANAKA

Abstract

In tightening and looseness characteristics of the screw, threaded surface and coefficient of friction of bearing surface greatly give the effect. By separating the threaded surface from coefficient of friction of bearing surface by not fastening condition but system equal to general coefficient of friction in order to obtain coefficient of friction of the screw, it was measured to the yielding zone of the bolt.
