Detailed Engineering Specifications

A high-performance industrial component, this M11x113mm hex head cap screw is precision manufactured from solid brass (UNS C26000 / Cartridge Brass), renowned for its excellent machinability, corrosion resistance against many chemicals and saltwater, and non-magnetic properties. The M11 nominal diameter provides significant tensile strength, while the 13mm length is suitable for joining thin to moderately thick materials. The 7mm hex head width allows for secure tightening with standard hex wrenches, facilitating efficient assembly and disassembly. Its inherent conductivity makes it ideal for electrical grounding and connection applications.
