S-90822A710 Length 4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction, ensuring long-term reliability in demanding industrial environments.
• Efficient installation through thread forming design that creates strong, secure threads without pre-tapping, reducing assembly time and labor costs.
• Enhanced grip and load distribution from the integrated flange, preventing loosening under vibration and improving joint integrity.
• Quick penetration in tough materials with a self-drilling tip that eliminates pilot holes, drilling through up to 0.21" thickness in steel and sheet metal.
• Secure, high-torque driving using an external hex head, allowing for easy installation with standard tools and minimizing stripping risks.
• Full-thread engagement along the 4" length for maximum holding power in deep or thick applications.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in global markets and sustainable operations.

Professional Applications & Engineering Value

These thread forming tapping screws are engineered to address common challenges in metal fabrication and assembly, such as material fatigue and installation inefficiency. The 410 stainless steel provides excellent strength and corrosion resistance, making them ideal for steel, stainless steel, and sheet metal applications where exposure to moisture or chemicals is a concern. The thread forming (BSD) design displaces material to create precise, high-strength threads without chips, reducing the risk of cross-threading and ensuring reliable fastening in structural components. Combined with the self-drilling tip, these screws eliminate the need for separate drilling operations, streamlining workflow in automotive, construction, and industrial machinery sectors. This results in faster assembly cycles, reduced component count, and enhanced durability in high-vibration environments.

Specification Summary & Compliance

These screws feature a 1/4"-14 thread with right-hand direction and fully threaded shank, adhering to standard inch system measurements for consistent performance. The hex head with external drive and 0.52" flange diameter ensures secure installation, while the drilling tip (No. 3 type) supports penetration up to 0.21" thickness. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and suitability for industrial use without hazardous substances.
