S-94155A139 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh environments.
• High-torque installation enabled by the square drive and No. 2 drive size, preventing cam-out and speeding up assembly.
• Strong thread-forming capability for secure, vibration-resistant fastening in sheet metal without needing pre-tapped holes.
• Optimized for 0.025" maximum drilling thickness, providing precise performance in thin sheet metal applications.
• Fully threaded design for maximum grip and uniform load distribution along the entire 1-1/4" length.
• Pan head style offers a low-profile, rounded finish that resists snagging and improves safety.
• Environmental compliance with RoHS 3 and REACH standards, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

These thread-forming tapping screws are engineered to solve common fastening challenges in sheet metal fabrication, HVAC systems, and electronic enclosures. The 18-8 Stainless Steel material provides excellent resistance to rust and oxidation, which is critical for outdoor or high-moisture environments. The A/AB screw type with a pointed tip and 12 threads per inch ensures easy starting and strong thread engagement, reducing the risk of stripping in thin materials. The pan head with square drive allows for high torque application without slippage, making them ideal for automated assembly lines where speed and reliability are paramount. By eliminating the need for separate tapping operations, these screws lower labor costs and increase production efficiency in industrial metalworking.

Specification Summary & Compliance

This No. 10 sheet metal tapping screw features a thread diameter of 0.19" and is fully threaded for consistent performance. It conforms to standard inch measurements and is designed for use with a No. 21 drill bit (0.159" diameter). The screw meets common industrial specifications for thread-forming tapping screws and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and safe for various manufacturing applications.
