S-94195A431 Length 4" Tapping Screws

Key Features & Benefits at a Glance

• Superior Drilling Efficiency: Integrated No. 3 drill tip and self-drilling design eliminate the need for pre-drilling, saving significant labor time and cost in steel and sheet metal assemblies.
• Exceptional Corrosion Resistance: Made from 410 Stainless Steel, these screws offer reliable performance and longevity in demanding industrial environments.
li>Optimized for Secure Fastening: The BSD thread forming action creates strong, durable threads in the parent material, providing high resistance to vibration loosening.
• Flush, Professional Finish: The standard flat head with an 82° countersink angle sits flush with the material surface for a clean, snag-free appearance and improved safety.
• High-Strength Application Range: Capable of drilling through materials up to 0.15" thick, making them ideal for a wide range of steel, stainless steel, and sheet metal projects.
• Reliable Drive Engagement: The Phillips No. 2 drive ensures a secure bit connection, reducing cam-out and enhancing installation speed and control.
• Compliant and Safe: Fully compliant with RoHS 3 and REACH regulations, ensuring environmental safety and suitability for global industrial supply chains.

Professional Applications & Engineering Value

These No. 10-16 self-drilling tapping screws are engineered to solve critical assembly challenges in metalworking and construction. The 410 Stainless Steel construction provides the necessary strength and corrosion resistance for long-term structural integrity in harsh conditions. The combination of the self-drilling tip and thread-forming BSD design streamlines the installation process by combining drilling and tapping into a single operation. This eliminates misalignment issues from separate drilling steps and creates a tighter, more vibration-resistant fit in materials like steel and sheet metal. The fully threaded shank and flat head profile ensure maximum clamping force and a smooth, finished surface, making them a high-value fastener for HVAC, metal framing, and industrial equipment manufacturing.
