S-94195A391 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Efficient self-drilling capability with No. 3 drill tip that eliminates pre-drilling, saving time and labor in aluminum and sheet metal applications
• High-strength thread forming design (BSD type) creates secure, vibration-resistant threads without chip removal
• Optimized drive engagement with Phillips No. 3 drive for reliable torque transmission and reduced cam-out risk
• Complete fastening coverage with full threading along the 2-1/2" length for maximum grip and load distribution
• Precision 82° countersink angle ensures flush mounting in standard applications for clean, professional finishes
• Regulatory compliance assurance with RoHS 3 and REACH compliance for safe use in global industrial markets

Professional Applications & Engineering Value

These No. 12 Phillips flat head tapping screws deliver exceptional value in aluminum and sheet metal fabrication where corrosion resistance and installation efficiency are critical. The 18-8 stainless steel composition provides reliable performance in environments exposed to moisture or chemicals, while the thread forming design (BSD type) creates strong, permanent threads without generating metal chips that could contaminate sensitive equipment. The integrated drilling tip (No. 3) penetrates up to 0.14" thickness, eliminating separate drilling operations and significantly reducing assembly time. The fully threaded 2-1/2" length ensures maximum engagement in varying material thicknesses, making these tapping screws ideal for HVAC systems, electronic enclosures, and architectural metalwork where both structural integrity and aesthetic finish matter.

Specification Summary & Compliance

These tapping screws feature precision thread forming with 14 threads per inch and 0.216" thread diameter, manufactured to standard BSD specifications for consistent performance. The flat head design incorporates an 82° countersink angle for proper seating in standard applications. All screws are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
