S-92220A169 10-32 x 7/8" ASTM A574 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating on alloy steel, extending service life in harsh environments
• Maximum thread reliability through Class 3A precision fit, ensuring secure fastening with minimal backlash
• Exceptional strength-to-weight ratio with 140,000 psi tensile strength, ideal for high-stress applications
• Enhanced durability from Rockwell C39 hardness, maintaining performance under repeated loading
• Space-saving low-profile design with reduced head height, perfect for confined assembly spaces
• Precision torque transmission via 3/32" hex drive socket, preventing tool slippage during installation
• Full thread engagement along the 7/8" length, providing consistent clamping force distribution

Professional Applications & Engineering Value

These 10-32 UNF low socket head cap screws deliver critical performance advantages in precision assemblies where space constraints and corrosion resistance are primary concerns. The black-oxide alloy steel construction provides superior protection against oxidation while maintaining the 140,000 psi tensile strength required for demanding mechanical applications. The Class 3A thread fit ensures vibration-resistant connections in equipment requiring repeated disassembly, while the low-profile socket head design enables installation in tight clearance applications across aerospace, automotive, and industrial machinery sectors. The combination of fine UNF threads and fully threaded configuration guarantees optimal load distribution across the entire fastener length.
