Detailed Engineering Specifications

Purpose-built for heavy-duty applications, this M19x38mm Hex Head Cap Screw leverages the inherent properties of polycarbonate to deliver outstanding performance. Polycarbonate provides excellent impact strength, high tensile strength, and superior resistance to a wide range of chemicals and UV radiation, making it suitable for environments where traditional metal fasteners would corrode or degrade. The M19 thread size ensures a secure and robust connection, with a nominal length of 38mm and a head width of 23mm for ample torque application and stability. Its non-conductive nature further expands its utility in specialized applications. This fastener is an engineered solution for critical assemblies requiring long-term reliability and minimal maintenance in harsh conditions.
