S-94195A401 Length 3 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 installation with a No. 3 drill tip that penetrates up to 0.175" thickness, eliminating the need for pre-drilling and saving labor time.
• Strong, secure thread formation using thread forming technology that creates durable, vibration-resistant threads in aluminum and sheet metal.
• Flush, professional finish thanks to the standard flat head with 82° countersink angle, providing a smooth surface and reducing snagging risks.
• Reliable drive engagement with a Phillips No. 3 drive style, offering good torque transfer and reducing cam-out during installation.
• Full-length threading for maximum grip and holding power along the entire 3-1/2" length, enhancing joint integrity.
• Compliance with environmental standards, being RoHS 3 and REACH compliant for safe, sustainable use in global supply chains.

Professional Applications & Engineering Value

These No. 14 Phillips flat head tapping screws are engineered to address common challenges in metal fabrication, such as material cracking and time-consuming pre-drilling. The 18-8 stainless steel provides excellent resistance to oxidation and chemical exposure, making them ideal for outdoor or corrosive environments. With a thread forming design, they displace material to form strong internal threads without cutting, which minimizes chip formation and enhances thread strength in aluminum and sheet metal applications. The integrated No. 3 drill tip and 82° countersink angle ensure quick penetration and a flush mount, streamlining assembly in HVAC, automotive, and construction projects while reducing installation errors and improving overall efficiency.

Specification Summary & Compliance

This screw features a thread diameter of 0.242" with approximately 14 threads per inch, adhering to common inch-series tolerances for consistent performance. It conforms to BSD tapping screw standards for thread forming applications and includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet stringent environmental and safety requirements for industrial use.
