S-90925A242 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in industrial environments.
• Enhanced torque transmission and reduced cam-out thanks to the T25 Torx drive, allowing for secure, high-torque installations.
• Efficient thread forming design that creates strong, permanent threads in sheet metal without pre-tapping, saving assembly time.
• Easy, self-starting installation with a fully threaded, pointed tip that penetrates sheet metal smoothly and reduces pilot hole requirements.
• Reliable, vibration-resistant hold from the standard pan head and fully threaded shank, maintaining clamp load in demanding applications.
• Broad compatibility with standard No. 21 drill bits and up to 0.025" sheet metal thickness, offering versatile use across projects.
• Compliance with RoHS 3 and REACH regulations, ensuring safe, environmentally responsible sourcing for global supply chains.

Professional Applications & Engineering Value

These No. 10 zinc-plated steel Torx tapping screws are specifically engineered for sheet metal fastening, where reliability and speed are critical. The thread forming (A/AB type) design displaces material to create robust, strip-resistant threads, eliminating the need for tapped holes and reducing assembly steps. Made from zinc-plated steel, they resist corrosion in humid or outdoor settings, while the T25 Torx drive ensures maximum torque transfer without slippage—ideal for automated or high-volume production lines. The fully threaded, pointed tip allows for quick starts and consistent engagement, making them a go-to solution for HVAC, electronics enclosures, and automotive panels where vibration resistance and long-term performance are non-negotiable.

Specification Summary & Compliance

This No. 10-12 x 1/2" screw features a 0.19" thread diameter with 12 threads per inch and a Class 2A fit for consistent engagement. It adheres to A/AB thread forming standards and is designed for use with a No. 21 drill bit (0.159" diameter). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), meeting stringent environmental and safety requirements for industrial components.
