Cotter Joint

This is a Cotter Joint modeled as a multi-body part in SOLIDWORKS 2023. A cotter joint is a temporary fastening used to connect two co-axial rods that are subjected to axial tensile or compressive forces. The model consists of three solid bodies—Socket, Spigot, and Key (Cotter)—all modeled within a single part file using the multi-body approach. The material assigned is plain carbon steel. This model is ideal for engineering students, mechanical designers, and educators looking for reference geometry for machine design coursework or projects.
