S-90086A833 10-32 x 1" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Self-tapping design eliminates the need for pre-tapped holes, reducing assembly time and labor costs in materials like aluminum and sheet metal.
• Zinc-plated steel construction provides a protective barrier against corrosion, extending the service life of your assemblies in various industrial environments.
• No. 2 Phillips drive offers a common and widely available interface for efficient installation with standard tools, minimizing driver slippage.
• 82° countersink angle and flat head ensure a flush, secure fit that minimizes protrusion and provides a clean, professional finish.
• 10-32 UNF fine thread delivers superior holding power and vibration resistance in softer metals and thin materials.
• Fully threaded shank maximizes grip and load distribution along the entire fastener length for a more secure and reliable connection.
• Compliance with ASME B18.6.3 guarantees dimensional accuracy and performance reliability, ensuring interchangeability and consistent quality.

Professional Applications & Engineering Value

These 10-32 UNF thread cutting screws are engineered to solve common fastening challenges in aluminum, brass, cast iron, and sheet metal assemblies. The zinc-plated steel material offers excellent durability, while the thread cutting (Type F) design allows the screw to form its own mating thread, eliminating the risk of cross-threading and reducing installation complexity. This is particularly valuable in high-volume production and maintenance scenarios where speed and reliability are critical. The combination of a standard 82° countersink and a flat head ensures a seamless finish that is both aesthetically pleasing and functionally secure, preventing snagging and improving safety. These tapping screws are a robust solution for electrical enclosures, machinery frames, and automotive components, providing long-term performance without the need for additional locking elements.

Specification Summary & Compliance

This product adheres to Class 2A dimensional tolerances for UNF (Unified National Fine) threads as specified in the ASME B18.6.3 standard. The manufacturing process ensures precise thread geometry for reliable engagement. It is also confirmed to be RoHS 3 (2015/863/EU) Compliant, meeting environmental regulations for hazardous substance restrictions, making it suitable for global supply chains and environmentally conscious engineering projects.
