S-92949A349 7/16"-14 x 3/4" ASME B18.3 Stainless Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments
• Exceptional mechanical strength delivering 70,000 psi tensile strength and Rockwell B55 hardness for heavy-duty applications
• Precise, reliable fastening ensured by Class 3A thread fit and UNC coarse threading for vibration resistance
• Quick installation and removal with 1/4" hex drive and fully threaded design for maximum engagement
• Broad regulatory compliance meeting ASME B18.3, RoHS 3, and REACH standards for global supply chain compatibility
• Optimized head design featuring a rounded button profile that reduces surface protrusion while maintaining high torque capability

Professional Applications & Engineering Value

Engineered for demanding industrial assemblies, these 7/16"-14 UNC screws with Class 3A thread fit provide exceptional clamp load retention in high-vibration machinery, automotive subsystems, and structural frameworks. The 18-8 stainless steel material combined with passivated finish resists chemical degradation in marine, chemical processing, and outdoor applications. The coarse threading and fully threaded design prevent cross-threading while enabling rapid installation in thick materials. With 70,000 psi tensile strength, these rounded head hex drive screws outperform standard fasteners in load-bearing joints while maintaining ASME B18.3 dimensional consistency for replacement part interoperability.

Specification Summary & Compliance
