S-94195A399 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments
• Efficient self-drilling capability with No. 3 drill tip, eliminating the need for pre-drilling and reducing installation time in aluminum and sheet metal
• Secure flush mounting thanks to the standard flat head profile with 82° countersink angle for clean, professional finishes
• Maximum drilling capacity of 0.175" providing versatility for various material thicknesses in metal fabrication
• Full threading design delivers consistent holding power along the entire 2-1/2" length for enhanced joint integrity
• Reliable thread forming (BSD type) creates strong, vibration-resistant threads in ductile materials without chip removal
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets international manufacturing standards

Professional Applications & Engineering Value

These No. 14 self-drilling tapping screws are engineered specifically for challenging aluminum and sheet metal applications where traditional fastening methods fall short. The combination of 18-8 stainless steel material and thread forming BSD design solves critical industrial pain points by eliminating cross-threading issues and providing exceptional resistance to vibration loosening. The fully threaded construction ensures maximum pull-out strength across the entire fastener length, while the No. 3 drill tip with precise geometry penetrates metal substrates efficiently without work hardening. This makes them ideal for HVAC systems, electronic enclosures, and metal framing where consistent performance and corrosion resistance are paramount for long-term structural integrity.

Specification Summary & Compliance

These tapping screws feature precise dimensional specifications including No. 14 screw size, 2-1/2" length, 14 TPI thread pitch, and standard flat head profile. Manufactured to thread forming standards with right-hand threading and BSD screw type classification. The products are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international requirements for industrial fastener applications.
