S-93085A013 2-56 x 5/32" FF-S-92, QQ-P-35, MS24693-C17, NASM24693, SAE AMS2700 Stainless Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with passivated 18-8 stainless steel construction, ideal for harsh industrial environments
• High tensile strength of 70,000 psi ensures reliable fastening under significant mechanical stress
• Precise Class 2A thread fit provides smooth assembly and consistent engagement in UNC coarse threading applications
• 100° countersink angle with standard flat head profile enables flush mounting for streamlined surfaces and improved aerodynamics
• Full threading along the 5/32" length maximizes grip strength and distribution across the entire fastener
• Rockwell B70 hardness offers excellent durability and resistance to wear during repeated installations
• Phillips drive size No. 1 ensures secure tool engagement and reduces cam-out risks during high-torque applications

Professional Applications & Engineering Value

Engineered for precision-critical assemblies, these 2-56 UNC flat head screws address common industrial challenges such as vibration loosening and material degradation. The passivated 18-8 stainless steel provides superior resistance to oxidation and chemical exposure, making them ideal for electronics enclosures, aerospace components, and marine hardware. The combination of coarse thread spacing and Class 2A thread fit ensures rapid installation with minimal cross-threading risks, while the fully threaded design enhances load distribution in thin-section materials. This Phillips machine screw is particularly valuable in applications requiring reliable, flush-mount fasteners that maintain integrity under dynamic loads and environmental stressors.
