S-92210A248 10-24 x 1 1/8" ASME B18.3, ASTM F879 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 rated at 70,000 psi ensures reliable performance under high-stress applications
• Precision Class 3A thread fit provides superior engagement and vibration resistance in critical assemblies
• Optimized flush mounting with 82° countersink angle and standard flat head profile for seamless surface integration
• Enhanced drive stability through hex drive design prevents cam-out and enables high-torque installation
• Full threading capability along the entire 1 1/8" length maximizes grip strength and load distribution
• Consistent mechanical properties with Rockwell B55 hardness balance durability with machinability

Professional Applications & Engineering Value

These 10-24 UNC flat head screws deliver critical engineering advantages where surface flushness and corrosion resistance are paramount. The 18-8 stainless steel composition combined with passivated finish creates a protective barrier against chemical exposure and atmospheric corrosion, extending service life in manufacturing equipment, marine hardware, and food processing machinery. The coarse thread spacing and Class 3A thread fit ensure rapid installation with minimal cross-threading risk while maintaining secure fastening in high-vibration environments. The hex drive configuration provides superior torque transmission compared to slotted alternatives, reducing installation time and tool wear in production line applications. These fully threaded fasteners distribute clamping force evenly across the entire engagement length, preventing joint loosening in dynamic load conditions.
