S-90315A516 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments.
• Efficient thread forming design creates strong, secure threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Optimized oval head profile with 82° countersink angle provides a flush, professional finish that minimizes snagging and improves safety.
• Reliable Phillips No. 2 drive ensures consistent torque transmission and reduces cam-out during installation.
• Full threading along 1-1/2" length delivers maximum grip and holding power across the entire fastener engagement.
• Precision dimensional accuracy with No. 10 screw size and 0.19" thread diameter ensures perfect fit with standard No. 21 drill bits.
• Comprehensive regulatory compliance with RoHS 3 and REACH standards guarantees environmental safety and global market acceptance.

Professional Applications & Engineering Value

These 18-8 stainless steel oval head tapping screws are engineered specifically for demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming tapping method (A/AB type) creates permanent, high-strength threads in metal substrates without chip formation, eliminating cleanup and ensuring vibration-resistant connections. The fully threaded design provides consistent clamping force across the entire 1-1/2" length, while the standard oval head profile with Phillips drive offers both aesthetic appeal and practical installation advantages. Ideal for HVAC systems, electrical enclosures, and metal fabrication projects, these screws deliver reliable performance where maximum drilling thickness of 0.025" is required, making them essential for precision assembly operations.
