S-90410A831 10-32 x 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Self-tapping efficiency with Type F thread cutting design eliminates the need for pre-tapped holes, reducing installation time and labor costs in brass, cast iron, and sheet metal.
• Superior corrosion resistance from 410 stainless steel construction ensures long-term reliability in harsh industrial environments, minimizing maintenance and replacement frequency.
• Secure fastening in fine-thread applications with 10-32 UNF threads providing enhanced vibration resistance and improved load distribution compared to coarse threads.
• Optimized drive engagement with No. 2 Phillips pan head offers reliable torque transmission and reduced cam-out risk for consistent, flush installations.
• Full-threaded shank design maximizes grip length and pull-out strength across the entire 3/4" length, ensuring robust connections in varied material thicknesses.
• Regulatory compliance assurance with RoHS 3 and REACH standards guarantees environmentally safe components for global supply chain integration.
• Precision-engineered blunt tip facilitates easier alignment and starts in pre-drilled holes (No. 21 drill bit recommended), reducing material splitting risks.

Professional Applications & Engineering Value

These 10-32 UNF thread cutting screws are engineered to address common industrial fastening challenges in brass, cast iron, and sheet metal assemblies. The Type F tapping method and fine UNF threads create precise, durable internal threads without requiring pre-threaded holes, significantly streamlining production workflows. Manufactured from 410 stainless steel, these screws resist oxidation and chemical exposure in demanding environments like HVAC systems, automotive components, and machinery frames. The Phillips pan head with No. 2 drive ensures uniform clamping force and seated installations, while the fully threaded 3/4" length accommodates variable material thicknesses—eliminating the need for multiple screw types and reducing inventory complexity for B2B procurement teams.

Specification Summary & Compliance

This product adheres to UNF fine thread standards (10-32) with a thread diameter of 0.19" and Class 2A tolerance for consistent fit. The thread cutting (Type F) design complies with industrial tapping screw specifications for use with a No. 21 drill bit (0.159" diameter). Regulatory conformity includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring restriction of hazardous substances in line with international environmental directives.
