S-94195A398 Length 2 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel construction ensures long-term reliability in harsh industrial environments, reducing replacement costs and maintenance downtime.
• Self-drilling tip eliminates pre-drilling requirements, saving significant labor time and streamlining assembly processes in aluminum and sheet metal applications.
• Full threading and thread forming (BSD) design creates strong, secure, and vibration-resistant threads in ductile materials, enhancing joint integrity.
• 82° flat head with standard profile provides a clean, flush finish when seated, ideal for applications requiring a smooth surface and reduced snagging.
• Capable of drilling through materials up to 0.175" thick, offering versatility for a range of standard gauge sheet metal and aluminum fabrication projects.
• Phillips No. 3 drive allows for efficient installation with common tools, improving operator control and reducing the risk of cam-out.
• Compliance with RoHS 3 and REACH regulations guarantees the screws are free from hazardous substances, making them suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

These No. 14 self-drilling tapping screws are engineered to solve critical challenges in metal fabrication and assembly. The 18-8 stainless steel material provides excellent resistance to oxidation and corrosion, which is vital for outdoor enclosures, HVAC systems, and architectural metalwork. The integrated drilling tip and thread forming (BSD) design work in tandem to penetrate and form precise right-hand threads in aluminum and sheet metal without pre-tapping, drastically reducing installation time and tooling requirements. This combination of a fully threaded shank and a flat head with an 82° countersink angle ensures a tight, flush fit that resists loosening under vibration, making these tapping screws a reliable, high-efficiency solution for production lines and field service applications.
