S-92210A421 10-32 x 2 3/4" ASME B18.3 Stainless Steel Hex Drive Flat Head 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 tensile strength of 70,000 psi ensures reliable performance under high-stress applications
• Precise Class 3A thread fit provides superior engagement and vibration resistance in critical assemblies
• Secure hex drive design (1/8") enables high-torque installation without cam-out risks
• Full threading along 2 3/4" length offers maximum adjustability and holding power
• 82° countersink angle ensures flush mounting for streamlined surfaces and improved aesthetics
• Rockwell B55 hardness maintains thread integrity and prevents stripping during repeated use

Professional Applications & Engineering Value

This 10-32 UNF flat head screw delivers critical engineering solutions where precision and durability are paramount. The 18-8 stainless steel material combined with passivated finish provides excellent resistance to corrosion and chemical exposure, making it ideal for marine, food processing, and outdoor equipment applications. The Class 3A thread fit with fine thread spacing ensures tight tolerances for vibration-prone assemblies, while the hex drive design allows for secure installation in confined spaces. These fully threaded fasteners maintain consistent 70,000 psi tensile strength throughout their length, providing reliable performance in structural frameworks, machinery mounts, and precision instrumentation where failure is not an option.
