S-90065A225 Length 2 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Excellent holding power through thread forming design that creates strong, permanent threads in sheet metal without pre-tapping
• Flush installation with standard flat head profile and 82° countersink angle for smooth, professional finishes
• Easy drive engagement with Phillips No. 3 drive style providing reliable torque transfer during installation
• Quick penetration thanks to fully threaded design and pointed tip that reduces installation time and effort
• Precise fitment with 10 threads per inch and 0.242" thread diameter ensuring secure fastening in sheet metal applications
• Optimized compatibility with standard 5.5mm drill bits for straightforward installation preparation

Professional Applications & Engineering Value

These No. 14 Phillips flat head tapping screws are specifically engineered for sheet metal applications where reliability and corrosion resistance are paramount. The 18-8 stainless steel composition provides exceptional durability against environmental factors, while the thread forming design creates permanent, high-strength connections by displacing material rather than removing it. This eliminates the need for separate tapping operations and reduces installation time significantly. The fully threaded configuration with pointed tip ensures quick starts and smooth penetration through metal sheets, while the 82° countersink angle allows for flush mounting that prevents snagging and maintains clean aesthetic lines. Ideal for HVAC systems, electrical enclosures, and industrial equipment assembly where vibration resistance and long-term performance are critical requirements.

Specification Summary & Compliance
