S-98248A220 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance and lightweight strength from premium 7075 aluminum construction, ideal for weight-sensitive industrial applications
• Efficient installation with integrated drilling tip that eliminates pre-drilling, saving labor time and reducing assembly steps
• Enhanced holding power and vibration resistance through thread forming technology that creates precise, secure threads in aluminum substrates
• Quick installation and high torque capability with external hex drive design that prevents stripping and allows for powerful tightening
• Increased bearing surface and stability from the integrated flange design that distributes load evenly and prevents pull-through
• Maximum thread engagement and superior fastening with fully threaded shank that ensures consistent holding strength along the entire length
• Precision threading for reliable performance with 18 TPI and 0.164" diameter threads that maintain tight tolerances in aluminum applications

Professional Applications & Engineering Value

Engineered specifically for aluminum fabrication and assembly, these thread forming tapping screws solve critical challenges in modern manufacturing. The combination of 7075 aluminum material and thread forming technology creates permanent, high-strength threads without tapping operations, eliminating chip formation issues common in aluminum workpieces. The integrated drilling tip with No. 2 geometry penetrates up to 0.098" thickness, streamlining production by combining drilling and fastening into a single operation. The flanged hex head design provides superior clamp load distribution while the external hex drive ensures maximum torque transmission without cam-out, making these BSD tapping screws ideal for high-volume assembly lines, aerospace components, and precision aluminum enclosures where weight reduction and corrosion resistance are paramount.
