S-90279A829 10-32 x 1/2" ASME B18.6.3 Steel Round Head Phillips Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding environments
• Exceptional tensile strength rated at 60,000 PSI for reliable load-bearing capacity and joint integrity
• Precise Class 2A thread fit for smooth installation and consistent engagement in UNF fine-thread applications
• Full threading design maximizes grip length and distributes stress evenly across the entire fastener
• Optimized Phillips No. 2 drive provides secure tool engagement and reduces cam-out during high-torque installation
• Rockwell B69 hardness maintains structural integrity under repeated stress and vibration
• Comprehensive regulatory compliance meets ASME B18.6.3 specifications while adhering to RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

These 10-32 UNF zinc-plated steel screws deliver critical performance advantages in industrial assembly applications where corrosion resistance and thread reliability are paramount. The fine UNF threading provides superior vibration resistance compared to coarse-thread alternatives, making them ideal for machinery, electronic enclosures, and precision equipment where loosening under dynamic loads is a concern. The rounded head profile with Phillips drive facilitates flush mounting while accommodating standard installation tools. With full threading extending the entire 1/2" length, these fasteners ensure maximum thread engagement in both thick and thin materials, eliminating the need for multiple screw types across different material thicknesses in your production line.
