Abstract

The tightening of the mechanically fastened joint such as a bolt and the nut assembly is a necessary and common operation in most machinery and mechanical system. The application of a torque to a nut, result in a clamping force in the bolt and nut fastener is a common engineering application. The main aim of this project is to investigate the effect of the thread condition on the resultant tension in the bolt. Beside that, is also investigating the effects of dissimilar bolt and material on the tightening process. The ER 420 Testing Hyperstatic Mechanical System is used to done the series o the experiment. The experiment is done on two different conditions of the bolt thread which is lubricant and without lubricant. Beside that, there are 3 different types of the material is chosen which is high tensile steel, galvanized zinc steel and stainless steel undergo the series of the experiment. The experiment resulted in a set of graph that clearly shown the relationship between the torque and stress created in bolt. Those result can be used as a reference guide for monitoring the performance of the bolts as this has been widely overlook in industry.
