S-90822A310 Length 3 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling operations with integrated self-drilling tip, saving labor time and reducing tool changes in steel and sheet metal assemblies
• Superior corrosion resistance from 410 stainless steel construction, ensuring long-term reliability in demanding industrial environments
• Enhanced driving torque capability with external hex head design, providing secure installation and preventing stripping during high-torque applications
• Secure fastening with thread forming technology that creates stronger threads in base materials without generating chips, improving joint integrity
• Integrated flange distributes load pressure across wider surface area, reducing material stress and preventing pull-through in thin sheet applications
• Optimized drill tip geometry (No. 3 type) penetrates up to 0.15" thickness in steel and stainless steel with minimal operator effort
• Full 3-1/2" thread engagement provides maximum holding power in deep material applications

Professional Applications & Engineering Value

These 410 stainless steel flanged tapping screws deliver exceptional value in metal fabrication and industrial assembly. The combination of self-drilling capability and thread forming technology addresses critical production challenges by eliminating separate drilling operations and creating stronger, more reliable threads in parent materials. The hex head design ensures positive driver engagement even in high-vibration environments, while the integrated flange provides built-in washer functionality that distributes clamping force effectively. Engineered specifically for steel, stainless steel, and sheet metal applications, these screws significantly reduce installation time while maintaining corrosion resistance essential for outdoor or harsh environment use. The fully threaded design ensures consistent holding power throughout the fastener length, making them ideal for structural connections in HVAC systems, electrical enclosures, and metal building components.

Specification Summary & Compliance

This No. 10-16 BSD tapping screw features a 0.19" thread diameter with 16 threads per inch in right-hand thread configuration. Manufactured to precise dimensional standards with fully threaded 3-1/2" length and external hex drive (0.313" width). The self-drilling tip (No. 3 type) provides 1/4" drilling length capable of penetrating up to 0.15" material thickness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
