S-92485A425 10-24 x 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior Material Durability: Made from 410 Stainless Steel for excellent corrosion resistance and long-lasting performance in demanding industrial environments.
• Efficient Self-Tapping Design: The Type F thread cutting tip creates its own threads in brass, cast iron, and sheet metal, reducing installation time and eliminating the need for pre-tapped holes.
• Optimized Drive Engagement: No. 2 Phillips drive ensures secure tool engagement and minimizes cam-out, providing reliable and efficient installation.
• Robust Thread Holding: UNC coarse thread spacing offers superior pull-out resistance and is less prone to cross-threading in softer materials.
• Flush Mounting Capability: Standard flat head with an 82° countersink angle allows for a smooth, flush finish when installed, enhancing both safety and aesthetics.
• Full Thread Engagement: Fully threaded 1-1/4" length provides maximum grip and holding power across the entire fastener length.
• Regulatory Compliance Assurance: Compliant with RoHS 3 and REACH regulations, ensuring they are safe for use and free from hazardous substances.

Professional Applications & Engineering Value

This 10-24 UNC coarse thread tapping screw is engineered to solve critical fastening challenges in materials like brass, cast iron, and sheet metal. Its Type F thread cutting design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in high-volume production. The 410 Stainless Steel construction provides the necessary strength and corrosion resistance for long-term reliability in harsh conditions, from outdoor enclosures to machinery frames. The combination of a flat head with a standard 82° countersink and a No. 2 Phillips drive ensures a secure, flush fit that prevents snagging and maintains a clean profile, which is crucial in applications where surface integrity and safety are paramount. This screw delivers consistent performance and durability, making it a trusted component for industrial assembly and maintenance.
