Professional Applications & Engineering Value

Engineered for demanding industrial applications, this 8-32 UNC rounded head screw combines 18-8 Stainless Steel material with a passivated finish to withstand corrosive environments while maintaining structural integrity. The flanged button head design eliminates the need for separate washers, reducing component count and assembly time in machinery, electrical enclosures, and automotive subsystems. With Class 3A thread fit and coarse UNC threading, it ensures rapid installation in sheet metal, plastics, and structural components while resisting vibration-induced loosening. The fully threaded configuration and 70,000 psi tensile strength provide consistent clamping force across the entire engagement length, making it ideal for high-stress applications where fastener failure is not an option.

Specification Summary & Compliance

This precision fastener maintains Class 3A thread fit per UNC standards with right-hand coarse threading (8-32). Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. Critical dimensions include 3/4" length, 0.164" thread diameter, and 0.359" flange diameter. The 18-8 Stainless Steel construction achieves Rockwell B70 hardness and 70,000 psi tensile strength, ensuring consistent performance in industrial fastening applications.
