• High-strength performance delivering 80,000 psi tensile strength and Rockwell B85 hardness for demanding applications
• Optimized drive efficiency with Phillips No. 2 drive style providing secure torque transmission and reduced cam-out
• Precision UNF fine threading (10-32) ensuring superior engagement and load distribution in critical assemblies
• Full threading design allowing maximum grip length and flexibility in various material thicknesses
• Regulatory compliance assurance meeting ASME B18.13 specifications and environmental standards (RoHS 3/REACH)

Professional Applications & Engineering Value

This 10-32 UNF stainless steel rounded head screw with integrated split lock washer addresses critical vibration-induced loosening in industrial equipment, machinery, and automotive assemblies. The passivated finish on both screw and washer components provides exceptional protection against corrosion in demanding environments, while the 18-8 stainless steel material maintains structural integrity under high-stress conditions. The combination of fine UNF threading and fully threaded design ensures maximum thread engagement and load distribution, making it ideal for applications requiring precise clamping force and reliability. The Phillips No. 2 drive facilitates efficient installation while the pan head profile offers a low-profile solution for space-constrained applications where secure fastening with vibration resistance is paramount.

Specification Summary & Compliance
