S-92210A196 8-32 x 5/8" ASME B18.3 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from 18-8 stainless steel and passivated finish, ideal for harsh industrial environments
• Exceptional tensile strength of 70,000 psi ensures reliable performance under high-stress applications
• Precision Class 3A thread fit provides secure, vibration-resistant fastening with minimal backlash
• Optimized hex drive design (3/32") enables efficient installation and removal with standard tools
• 82° countersink angle creates flush surface finishes for streamlined assemblies
• Full threading along the 5/8" length maximizes grip and load distribution
• Comprehensive compliance with ASME B18.3, RoHS 3, and REACH ensures regulatory adherence

Professional Applications & Engineering Value

These 8-32 UNC flat head screws deliver critical engineering value through their 18-8 stainless steel construction and passivated finish, which collectively combat corrosion in demanding environments like marine equipment, food processing machinery, and outdoor structures. The coarse thread spacing and Class 3A thread fit prevent loosening under vibration, making them ideal for heavy-duty fastening in automotive assemblies and industrial machinery. The hex drive style ensures secure tool engagement during high-torque installation, while the 82° countersink maintains aerodynamic and aesthetic surfaces in precision applications. These features address common pain points of fastener failure, corrosion-induced maintenance, and installation inefficiency.

Specification Summary & Compliance

This product maintains Class 3A thread fit per UNC standards with precise dimensional control. Manufacturing follows ASME B18.3 specifications for consistent quality. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency.
