S-90203A118 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Efficient self-drilling capability with No. 3 drill tip eliminates pre-drilling, saving labor time and reducing tool changes in aluminum and sheet metal assembly.
• Superior corrosion resistance from 18-8 stainless steel construction ensures long-term reliability in humid or demanding industrial environments.
• Secure, cam-out resistant installation with square drive design provides positive torque transfer and reduces fastener damage during high-torque applications.
• Full thread engagement along the 1-1/2" length delivers maximum holding power and vibration resistance in thin materials.
• Optimized thread forming design creates strong, clean threads in ductile materials without chip removal, improving joint integrity.
• Pan head with rounded profile offers a finished appearance while providing good bearing surface for secure clamping.
• Regulatory compliance ready with RoHS 3 and REACH certifications for use in regulated markets and environmentally conscious operations.

Professional Applications & Engineering Value

These 18-8 stainless steel self-drilling tapping screws are engineered specifically for aluminum and sheet metal fabrication where corrosion resistance and installation efficiency are critical. The thread forming design cold-forms mating threads without generating chips, preventing contamination in electrical enclosures, HVAC systems, and automotive components. The integrated No. 3 drill tip penetrates up to 0.15" thickness, eliminating separate drilling operations in production lines. The square drive prevents driver slippage during high-torque installation, reducing workplace injuries and fastener damage. Combined with the fully threaded shank and pan head configuration, these screws provide reliable fastening solutions for metal building products, electronic chassis, and industrial equipment where vibration resistance and aesthetic finish matter.

Specification Summary & Compliance

This No. 10-16 x 1-1/2" tapping screw features right-hand thread direction with approximately 16 threads per inch and Class 2A thread fit for standard industrial applications. Manufactured from 18-8 stainless steel with a rounded pan head profile and square drive (No. 2 size). The screw meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for hazardous substance restrictions, ensuring environmental regulatory adherence for global distribution and use.
