S-90410A199 8-32 x 1" 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: Thread cutting (Type F) action creates precise mating threads in brass, cast iron, and sheet metal, eliminating the need for pre-tapped holes and speeding up assembly.
• Reliable Fastening & Grip: Coarse UNC threads and a fully threaded shank provide maximum holding power and resistance to vibration loosening.
• Optimized Drive & Installation: The Phillips No. 2 drive and standard pan head offer a secure, cam-out resistant fit for efficient installation with common tools.
• Pre-Sized for Precision: Requires a standard No. 29 drill bit (0.136") for the pilot hole, ensuring a perfect fit and optimal thread engagement every time.
• Broad Industrial Compliance: Meets RoHS 3 and REACH regulations, making them suitable for use in regulated industries and global supply chains.

Professional Applications & Engineering Value

This 8-32 UNC thread cutting tapping screw is engineered to solve common fastening challenges in metalworking and fabrication. Its Type F thread cutting design allows it to form strong, clean threads directly in brass, cast iron, and sheet metal substrates, eliminating the time and cost associated with tapping operations. The 410 stainless steel construction provides the necessary strength and corrosion resistance for durable assemblies in harsh conditions, from outdoor enclosures to machinery. The combination of a coarse thread and Phillips drive ensures quick, reliable installation with high clamp load, reducing the risk of strip-out and maintaining joint integrity under vibration. This makes it an indispensable tapping screw for production lines, maintenance, and OEM applications where speed, reliability, and compliance are critical.
