A spanner or span is a metallic tool whose end fits round a nut or bolt so that you can turn it to loosen or tighten it. Spanner is designed to grip a nut or bolt head. In this paper, Open Ended Spanner is taken into consideration for the study of structural analysis. The open-ended spanner has a U-Shaped that grips the two opposite faces of a hexagonal bolt or nut. The main aim of this paper is to evaluate the structural analysis of the Spanner Bolt Assembly. Input will be the Spanner Bolt Assembly CAD model and output will be deformation and stress plots. The CAD model and Analysis operations are performed using Catia and Ansys Workbench respectively. Structural analysis is performed on Spanner Bolt Assembly with Structural Steel material to validate Equivalent stress and Total Deformation.
