S-90356A291 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black Oxide coated 18-8 Stainless Steel construction, ideal for harsh industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Optimized for sheet metal applications with pointed tip and A/AB screw type for secure fastening in materials up to 0.025" thickness
• Reliable Phillips drive system (No. 2 size) provides secure torque transfer and prevents cam-out during installation
• Full threading along 3/4" length ensures maximum grip and uniform stress distribution in assembled components
• Pan head design with standard rounded profile offers low-profile installation and smooth surface finish
• Comprehensive regulatory compliance with RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These No. 10 x 3/4" Black Oxide 18-8 Stainless Steel tapping screws deliver exceptional performance in demanding sheet metal applications where corrosion resistance and installation efficiency are critical. The thread forming technology eliminates the need for separate tapping operations, creating precise mating threads that resist vibration loosening while maintaining material integrity. The combination of 18-8 Stainless Steel with Black Oxide coating provides enhanced surface protection against oxidation and chemical exposure, making these Phillips pan head screws ideal for HVAC systems, electronic enclosures, automotive components, and industrial machinery where reliable fastening in thin-gauge materials is essential. The fully threaded design ensures consistent clamping force distribution across the entire engagement length.
