S-90096A426 8-32 x 1/2" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• Effortless installation and high torque capability through the combined external hex/Phillips drive, reducing tool slippage and assembly time.
• Reliable thread-cutting action with Type F design and UNC coarse spacing, enabling secure fastening in aluminum, brass, cast iron, and sheet metal without pre-tapping.
• Enhanced load distribution and vibration resistance thanks to the integrated flange, minimizing loosening under dynamic conditions.
• Full threading for maximum grip length, providing consistent holding power across the entire 1/2" length in various material thicknesses.
• Precision compatibility with No. 26 drill bits (0.147" diameter), ensuring accurate hole preparation and optimal thread engagement.
• Industry compliance assurance meeting ASME B18.6.3 standards and RoHS 3 regulations, guaranteeing quality and environmental safety for professional applications.

Professional Applications & Engineering Value

Engineered for demanding industrial fastening, these 8-32 zinc-plated steel tapping screws deliver exceptional value in assemblies involving aluminum, brass, cast iron, and sheet metal. The thread-cutting (Type F) design with UNC coarse threads eliminates the need for separate tapping operations, reducing labor costs and speeding up production cycles. The zinc-plated finish provides a protective barrier against oxidation, extending service life in environments exposed to moisture or chemicals. Combined with the external hex/Phillips drive, these screws allow for high-torque installation without cam-out, ensuring secure connections in automotive, machinery, and metal fabrication projects. The flange feature further enhances stability by increasing the bearing surface, preventing pull-through in thin materials and maintaining joint integrity under vibration.
