S-90033A230 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior Corrosion Resistance: Black-oxide steel finish provides enhanced durability and protection against rust in demanding industrial environments.
• Efficient Thread Forming Design: A/AB tapping screw type with thread forming method creates strong, reliable threads in sheet metal without pre-tapping, reducing installation time and effort.
• Optimal Sheet Metal Fastening: Fully threaded No. 8-15 design with 0.164" diameter and 15 TPI ensures maximum grip and pull-out resistance in sheet metal applications up to 0.025" thickness.
• Flush, Professional Finish: Standard flat head with 82° countersink angle sits perfectly flush with surfaces, preventing snagging and providing a clean appearance.
• Reliable Drive Performance: No. 2 Phillips drive offers secure torque transmission and reduces cam-out risk during high-torque installations.
• Precision Compatibility: Designed for use with No. 29 drill bit (0.136" diameter), ensuring accurate hole preparation and consistent fastening results.
• Environmental Compliance Assurance: Meets RoHS 3 and REACH regulations, guaranteeing safe, sustainable use in global industrial supply chains.

Professional Applications & Engineering Value

These Black-Oxide Steel Phillips flat head tapping screws deliver exceptional engineering value for sheet metal applications where vibration resistance and long-term reliability are critical. The thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in high-volume production environments. The combination of No. 8-15 thread configuration with fully threaded construction ensures maximum thread engagement in materials up to 0.025" thickness, preventing loosening under dynamic loads. The 82° countersink angle provides a secure, flush fit that maintains surface integrity while the Black-Oxide coating offers superior corrosion protection in harsh industrial conditions, making these tapping screws ideal for HVAC systems, electronic enclosures, automotive components, and machinery assemblies requiring durable, compliant fastening solutions.
