S-90822A382 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling tip technology eliminates pre-drilling requirements, saving time and labor costs in steel and sheet metal applications
• 410 stainless steel construction provides excellent corrosion resistance for durable performance in demanding industrial environments
• Integrated flange design distributes clamping pressure evenly, reducing the risk of material damage and improving joint integrity
• External hex drive ensures secure tool engagement and high torque transmission during installation
• Thread forming design (BSD type) creates strong, permanent threads in base materials without generating chips
• Full threading along 1-3/4" length delivers maximum grip and holding power throughout the fastener's engagement
• RoHS 3 and REACH compliance guarantees environmental responsibility and regulatory acceptance for global manufacturing operations

Professional Applications & Engineering Value

This No. 8-18 flanged tapping screw delivers exceptional engineering value through its 410 stainless steel composition and self-drilling tip technology. The thread forming BSD design creates precise, high-strength threads in steel, stainless steel, and sheet metal applications without chip removal, preventing contamination in sensitive assemblies. The integrated No. 2 drill tip with 3/16" length efficiently penetrates materials up to 0.098" thick, eliminating secondary drilling operations and reducing installation time by up to 50%. The external hex drive provides superior torque transmission compared to Phillips drives, minimizing cam-out and tool wear. These features make it ideal for HVAC systems, electrical enclosures, and metal fabrication where corrosion resistance and installation efficiency are critical.

Specification Summary & Compliance

This flanged tapping screw features precise No. 8-18 thread specifications with 0.164" diameter and 18 threads per inch, manufactured to standard inch system tolerances. The BSD thread forming design ensures consistent thread engagement without pre-tapping. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances. The fastener's dimensional accuracy, including 1/4" head width, 0.141" head height, and 0.348" flange diameter, ensures reliable performance in industrial fastening applications.
