S-90065A197 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in demanding industrial environments.
• Efficient thread forming action with Type A design creates strong, secure threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Optimal flush mounting thanks to the standard flat head profile and 82° countersink angle, providing a smooth, professional finish.
• Reliable drive engagement with a No. 2 Phillips drive, minimizing cam-out and ensuring consistent torque application during installation.
• Full-length threading offers maximum grip and holding power along the entire 3/4" length, enhancing joint integrity in sheet metal applications.
• Precision compatibility with a No. 29 drill bit (0.136" diameter), simplifying hole preparation for up to 0.025" maximum drilling thickness.
• Environmental and regulatory compliance with RoHS 3 and REACH standards, ensuring safe, sustainable use in global supply chains.

Professional Applications & Engineering Value

This No. 8 x 3/4" Phillips flat head tapping screw is engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion. The 18-8 stainless steel provides excellent resistance to rust and oxidation, ideal for outdoor or humid conditions. Its thread forming Type A design cold-forms threads into the base material, eliminating chips and creating a tighter, vibration-resistant fit that prevents loosening. The fully threaded right-hand configuration ensures uniform stress distribution, while the 82° countersink angle allows for a flush installation, reducing snagging risks in assembled products. These features make it a reliable choice for HVAC systems, electronic enclosures, and automotive panels, where durability and precision are critical.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.164" and approximately 15 threads per inch, ensuring precise fit in sheet metal applications. It is manufactured to common industrial tolerances for consistent performance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming it is free of hazardous substances and suitable for regulated markets.
