S-90822A537 Length 4 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Effortless installation with integrated No. 3 drill tip that eliminates pre-drilling, saving time and labor costs in steel, stainless steel, and sheet metal assemblies.
• Superior corrosion resistance provided by 410 Stainless Steel material, ensuring long-term reliability in harsh industrial environments.
• Enhanced load distribution and vibration resistance from the integrated flange design, which acts as a built-in washer for secure, stable fastening.
• High-torque application capability due to the external hex drive and flanged hex head, allowing for powerful driving without stripping.
• Strong, reliable thread formation through the thread forming (BSD) tapping method, creating secure, strip-resistant threads in ductile metals.
• Maximum material penetration with a 5/16" drill tip capable of drilling through materials up to 0.21" thick, ideal for heavy-duty applications.
• Full-length threading ensures consistent grip along the entire 4-1/2" length, providing uniform clamping force in various material thicknesses.

Professional Applications & Engineering Value

This heavy-duty self-drilling tapping screw is specifically engineered to address common challenges in metal fabrication and construction. The 410 Stainless Steel construction delivers excellent corrosion resistance, making it suitable for outdoor or corrosive environments where fastener integrity is critical. The thread forming design (BSD type) displaces material rather than cutting it, resulting in stronger threads with reduced risk of loosening under vibration—a common issue in automotive, HVAC, and structural steel applications. The No. 3 drill tip with 5/16" length efficiently penetrates up to 0.21" thick steel, stainless steel, and sheet metal, eliminating separate drilling operations and significantly reducing assembly time. The flanged hex head provides both superior torque transfer during installation and increased bearing surface, preventing pull-through in thin materials while maintaining a professional finish.

Specification Summary & Compliance

This screw features a No. 14 size with 0.242" thread diameter and 14 TPI right-hand threads, following standard inch measurements. The fully threaded 4-1/2" length and external hex drive ensure consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and industrial compliance for global sourcing requirements.
