S-91500A153 6-32 x 1" ASME B18.6.3 Stainless Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance in harsh environments due to 316 stainless steel construction and passivated finish
• Superior mechanical strength with 70,000 psi tensile strength and Rockwell B80 hardness for reliable, long-term performance
• Precise, secure fastening ensured by Class 2A thread fit and UNC coarse threading for easier alignment and reduced cross-threading risk
• Flush, low-profile installation with a standard 82° countersink angle flat head, ideal for applications where a smooth surface is critical
• Efficient installation and removal with a No. 2 Phillips drive, providing common tool compatibility and good torque transfer
• Full-length threading offers maximum grip and holding power along the entire 1-inch shank length
• Guaranteed quality and safety through compliance with ASME B18.6.3, RoHS 3, and REACH regulations

Professional Applications & Engineering Value

These 6-32 UNC flat head screws are engineered from 316 stainless steel to solve critical challenges in corrosive and demanding industrial settings. The passivated finish enhances the material's innate resistance to chemicals, saltwater, and extreme temperatures, making these Phillips drive screws ideal for marine equipment, chemical processing plants, and food-grade machinery. The fully threaded design and coarse thread provide excellent pull-out strength and vibration resistance, ensuring secure fastening in metals and plastics. With a standard 82° countersink angle, they sit flush to prevent snagging and maintain aerodynamic or hygienic surfaces. This combination of corrosion resistance, mechanical integrity, and regulatory compliance delivers reliable performance in applications where failure is not an option.
