S-90925A267 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T27 Torx drive, reducing cam-out and tool wear for efficient installation
• Enhanced corrosion resistance through zinc-plated steel construction, extending service life in industrial environments
• Maximum holding power in sheet metal up to 0.025" thickness with thread-forming design that creates strong, permanent threads
• Full-length threading provides consistent engagement along the entire 1/2" length for reliable fastening
• Streamlined installation with pointed tip and standard pan head design for easy alignment and flush mounting
• Precise compatibility with 3/16" drill bits, ensuring proper hole sizing for optimal thread formation
• Regulatory compliance meeting RoHS 3 and REACH standards for safe use across various industrial applications

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws with T27 Torx drive are engineered specifically for sheet metal applications where reliable fastening is critical. The thread-forming design eliminates the need for separate tapping operations, creating strong, permanent threads in materials up to 0.025" thick without generating chips. This makes them ideal for assembly lines where efficiency and clean installation are paramount. The combination of zinc-plated steel construction and fully threaded configuration ensures excellent corrosion resistance and consistent holding power throughout the fastener's length. These industrial fasteners are particularly valuable in electrical enclosures, HVAC systems, and metal fabrication where vibration resistance and long-term reliability are essential requirements.

Specification Summary & Compliance

These tapping screws feature a No. 12 screw size with 0.216" thread diameter and 11 threads per inch, manufactured to standard thread forming specifications. The pan head design with 0.425" diameter and 0.151" height provides ample bearing surface for secure fastening. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet current environmental and safety standards for industrial use worldwide. Proper installation requires a 3/16" drill bit (0.1875" diameter) for optimal performance in the specified material thickness.
