S-90395A203 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Maximum torque transmission through No. 2 square drive that prevents cam-out and ensures secure installation
• Complete thread engagement with fully threaded design for consistent holding power along the entire 1-1/2" length
• Optimized for sheet metal applications with precise 0.164" thread diameter and 15 TPI for reliable performance in materials up to 0.025" thickness
• Secure fastening solution featuring pan head design that provides excellent bearing surface without sinking into materials
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The A/AB thread forming design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs in high-volume production environments. The fully threaded construction ensures maximum pull-out resistance and vibration resistance, critical for automotive, HVAC, and electrical enclosure applications where joint integrity is paramount. The combination of No. 2 square drive and pan head configuration provides optimal torque transmission while maintaining a low-profile appearance. Engineered for materials up to 0.025" thickness, these screws maintain thread integrity without stripping or damaging thin-gauge metals, making them ideal for precision sheet metal work where material distortion must be minimized.

Specification Summary & Compliance

These No. 8-15 x 1-1/2" tapping screws feature precise 0.164" thread diameter with 15 threads per inch in right-hand orientation. The fully threaded design ensures consistent performance across the entire length, while the pointed tip facilitates easy starting in pre-drilled holes sized for No. 29 drill bit (0.136" diameter). Manufactured to industry standards for thread forming sheet metal screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the strictest requirements for hazardous substance restrictions in industrial applications.
