• Fully threaded design offers maximum grip length and uniform load distribution
• Fine UNF threading (10-32) delivers superior vibration resistance compared to coarse threads

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this black-oxide alloy steel socket head cap screw addresses critical challenges in machinery assembly, automotive components, and precision equipment. The 10-32 UNF fine thread configuration provides enhanced vibration resistance in dynamic environments, while the Class 3A thread fit ensures precise engagement with mating components. The black-oxide surface treatment offers superior corrosion protection without compromising dimensional accuracy, making it ideal for applications requiring both environmental resistance and tight tolerances. The combination of 170,000 psi tensile strength and Rockwell C37 hardness ensures reliable performance in high-stress applications where fastener failure is not an option.
