Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this M20 hex head cap screw is forged from high-grade brass, ensuring excellent machinability, ductility, and natural resistance to corrosion, especially in marine or chemically aggressive environments. The M20 thread designation signifies a nominal major diameter of 20mm, and a length of 96mm provides substantial engagement for secure fastening. The 12mm hex head width allows for optimal torque application with standard tooling, preventing over-tightening or stripping. This fastener is well-suited for applications requiring both strength and visual appeal, such as in architectural hardware, electrical connectors, and decorative assemblies.
