S-90822A536 Length 3 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in harsh industrial environments
• Efficient installation with self-drilling tip that eliminates pre-drilling requirements, saving time and labor costs
• Enhanced grip and stability through the flanged design that distributes load evenly and prevents loosening under vibration
• High torque capability with external hex drive that allows for secure tightening with standard tools
• Reliable thread formation with thread forming tapping method that creates strong, permanent threads in base materials
• Maximum material penetration capable of drilling through up to 0.21" thickness of steel, stainless steel, and sheet metal
• Full-thread engagement along the entire 3-1/2" length for superior holding power in demanding applications

Professional Applications & Engineering Value

These No. 14 flanged tapping screws deliver exceptional value in industrial fastening applications where reliability and efficiency are paramount. The 410 stainless steel composition provides excellent corrosion resistance, making these screws ideal for outdoor equipment, marine applications, and chemical processing facilities. The combination of thread forming technology and self-drilling tip eliminates the need for separate drilling and tapping operations, significantly reducing installation time and labor costs in steel, stainless steel, and sheet metal assemblies. The external hex drive ensures high torque transmission without stripping, while the flanged design provides superior clamping force distribution, preventing material distortion and maintaining joint integrity under vibration and dynamic loads commonly encountered in heavy machinery, structural frameworks, and industrial equipment manufacturing.
