In this paper an experimental study on shear loaded bolted joint is presented. Before beginning experimental tests, 3D finite elements simulations are turned for a symmetrical bolted joint to show the assembly behavior and choose suitable parameters. The shear loading is applied by a piston alimented with a hydraulic hand pump. Screws are instrumented with strain gauges to acquire data and analyze stresses applied on bolts. Many experimental tests are conducted. In each one, dimensions and friction factor of contact interface are varied. Results are used to analyze the bolt joint behavior and determine the more significant assembly parameters on screws stresses.
