S-90273A836 10-32 x 1 1/2" ASME B18.6.3 Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Precise flush mounting with standard 82° countersink angle and flat head design for seamless surface integration
• High torque transmission through No. 2 Phillips drive, reducing cam-out and tool slippage during installation
• Exceptional load-bearing capacity with 60,000 psi tensile strength and Rockwell B70 hardness for reliable performance under stress
• Consistent thread engagement with Class 2A thread fit and UNF fine threading for vibration-resistant fastening
• Full-length fastening coverage with completely threaded 1½" length for maximum grip range and holding power
• Regulatory compliance assurance meeting ASME B18.6.3 specifications and environmental standards (RoHS 3, REACH)

Professional Applications & Engineering Value

These 10-32 UNF flat head screws deliver critical engineering solutions where surface flushness and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for industrial equipment, machinery assemblies, and outdoor applications. The UNF fine threading offers superior resistance to vibrational loosening compared to coarse threads, making these Phillips drive screws ideal for precision assemblies in automotive, aerospace, and electronic enclosures. The fully threaded design ensures maximum thread contact throughout the entire 1½" length, distributing load evenly and preventing joint failure. With their standard 82° countersink angle, these screws sit perfectly flush in machined surfaces, eliminating protrusions that could interfere with moving components or create safety hazards in industrial settings.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 standards with Class 2A thread fit tolerance for consistent installation performance. Features UNF (Unified National Fine) 10-32 threading with precise thread spacing and diameter specifications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The standard flat head profile with 82° countersink angle maintains dimensional consistency with industry-standard counterbored holes.
