S-94195A432 Length 4 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Efficient Self-Drilling Design – Eliminates pre-drilling with integrated No. 3 drill tip, saving labor time and reducing installation steps in steel and sheet metal.
• Superior Material Durability – Made from 410 stainless steel for excellent corrosion resistance and long-term reliability in harsh industrial environments.
• Optimized Thread Engagement – No. 10-16 thread forming (BSD) design creates strong, secure threads in metal substrates without tapping fluid.
• Flush, Professional Finish – Standard flat head with 82° countersink angle sits flush with surfaces, preventing snagging and improving aesthetics.
• High Drilling Capacity – Capable of drilling through materials up to 0.15" thick, ideal for standard sheet metal and steel assemblies.
• Secure Phillips Drive – No. 2 Phillips drive provides reliable torque transfer and reduces cam-out during installation.
• Full-Length Threading – Fully threaded shank ensures maximum grip and holding power across the entire fastener length.

Professional Applications & Engineering Value

These No. 10-16 self-drilling tapping screws deliver exceptional value in metal fabrication and construction applications where speed and reliability are critical. The 410 stainless steel construction provides inherent corrosion resistance, making these BSD thread forming screws suitable for outdoor equipment, HVAC systems, and industrial machinery exposed to moisture. The integrated No. 3 drill tip and 82° countersink angle work together to create clean, flush installations in steel, stainless steel, and sheet metal without separate drilling operations. This combination of self-drilling capability and thread forming design eliminates the need for pilot holes and tapping operations, significantly reducing assembly time while maintaining strong, vibration-resistant connections in metal-to-metal applications.

Specification Summary & Compliance

These 4-1/2" self-drilling screws feature precision No. 10-16 thread forming (BSD) design with right-hand threading and standard flat head profile. The screws maintain consistent dimensional accuracy with a head diameter of 0.362" and are fully threaded for maximum engagement. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring they meet current industrial regulatory requirements for hazardous substance restrictions.
