S-90822A330 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated No. 2 drill tip that penetrates up to 0.098" thickness in steel and sheet metal
• Superior corrosion resistance provided by 410 stainless steel construction for extended service life in demanding industrial environments
• Enhanced holding power and vibration resistance through thread forming technology that creates stronger mating threads in parent material
• Streamlined installation process with external hex drive and flanged design that eliminates the need for separate washers
• Reliable performance in multiple materials including steel, stainless steel, and sheet metal applications
• Environmental compliance assurance with RoHS 3 and REACH regulations for global manufacturing applications
• Secure fastening in tight spaces with compact 1/4" head width and right-hand threading for standard installation

Professional Applications & Engineering Value

This No. 8-18 flanged tapping screw delivers exceptional engineering value by solving critical installation challenges in metal fabrication and assembly. The 410 stainless steel construction provides excellent corrosion resistance while the thread forming technology creates permanent, high-strength threads without chip formation. The integrated No. 2 drill tip eliminates secondary drilling operations, significantly reducing assembly time and labor costs in sheet metal and steel applications. The flanged hex head design distributes clamping force evenly while the external hex drive ensures positive torque transmission during installation. These self-drilling screws are particularly valuable in high-volume production environments where efficiency and reliability are paramount, making them ideal for HVAC systems, electrical enclosures, and metal framework assemblies.
