              Introduction Embedded brass nuts, also known as insert nuts, are widely used in plastic injection molding to provide strong, reusable threaded connections. These nuts are typically inserted into plastic bosses or pillars during or after the molding process. However, issues such as bulging, cracking, low pull-out or torque strength, misalignment, surface burns, and flash can arise due to material properties, design flaws, or process parameters. This article outlines these problems and offers proven solutions based on mechanical engineering principles, emphasizing structural optimization and material considerations to achieve high-quality, durable assemblies. Adhering to standards like ISO 965 for threading and ASTM D638 for tensile testing ensures that installations meet industry requirements.
