S-91771A837 10-32 x 1 3/4" ASME B18.6.3 Stainless Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with passivated 18-8 stainless steel construction for extended service life in harsh environments
• Precise flush mounting thanks to the standard 82° countersink angle and flat head design that sits perfectly flush with surfaces
• Exceptional mechanical strength with 80,000 psi tensile strength and Rockwell B80 hardness for heavy-duty applications
• Reliable fine thread engagement with UNF 10-32 threads and Class 2A fit ensuring vibration-resistant fastening
• Optimized drive efficiency through Phillips No. 2 drive that prevents cam-out during high-torque installation
• Full threading coverage across the entire 1 3/4" length for maximum grip strength and load distribution
• Regulatory compliance assurance meeting ASME B18.6.3, RoHS 3, and REACH standards for global industrial use

Professional Applications & Engineering Value

These 10-32 UNF flat head screws deliver critical performance in demanding industrial applications where corrosion resistance and structural integrity are paramount. The passivated 18-8 stainless steel construction provides exceptional protection against chemical exposure and atmospheric corrosion, while the fine thread design maintains secure fastening in vibration-prone environments. The 82° countersink angle and flat head profile enable seamless flush mounting in precision assemblies, eliminating protrusions that could interfere with moving components. With fully threaded construction and 80,000 psi tensile strength, these screws distribute stress evenly and withstand substantial mechanical loads in machinery, electronic enclosures, and structural frameworks where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent mating with UNF nuts and threaded components. The 10-32 UNF fine threads provide superior engagement in thin materials and precision assemblies. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptance. Right-hand threading direction with standard Phillips No. 2 drive configuration for universal compatibility with industrial driving tools.
