چکیده انگلیسی
Tightening a bolt to a torque value is the most popular means of controlling the preload provided by a threaded fastener. However, repeated tightening and loosening of a threaded fastener, can have a dramatic effect on the friction coefficient. These changes will, in turn, will affect the preload and can, therefore, have an adverse effect on the structural integrity of an assembly. This study investigates the effect of repeated tightening on electro-zinc plated (EZP) nuts, bolts and washers. It is found that significant wear of the contact surfaces of the bolt/nut thread and nut face occurs upon repeated tightening.
