S-90935A203 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel coating, extending service life in demanding industrial environments.
• Strong, reliable thread forming design creates secure, vibration-resistant threads in sheet metal without pre-tapping.
• Easy installation and reduced tool wear with Phillips No. 2 drive, ensuring consistent torque application and minimal slippage.
• Maximum holding power from fully threaded shank, distributing load evenly for durable sheet metal assemblies.
• Precision compatibility with No. 29 drill bits (0.136" diameter), streamlining workflow and reducing setup errors.
• Optimized for thin materials, effectively fastening sheet metal up to 0.025" thick with minimal risk of stripping.
• Compliance with global safety standards, including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

This thread forming tapping screw is engineered to solve common challenges in sheet metal fabrication, such as material fatigue and thread stripping. The Black-Oxide Steel construction provides a protective layer that resists rust and corrosion, crucial for outdoor or high-moisture environments. Its A/AB thread forming design displaces material to form strong, precise threads without chips, reducing the need for secondary operations and improving assembly speed. The fully threaded No. 8-15 configuration ensures consistent grip across the entire length, enhancing joint integrity in sheet metal applications like HVAC systems, electronic enclosures, and automotive panels. With a Phillips pan head, it offers a low-profile finish that sits flush, minimizing snagging while maintaining easy access for drivers.

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 fits in pre-drilled holes. It is designed for use with a No. 29 drill bit (0.136" diameter) and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it meets stringent environmental and safety standards for industrial use. The right-hand threading and pointed tip facilitate smooth insertion in sheet metal up to 0.025" thickness, providing reliable performance in various fastening scenarios.
