Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- High-torque driving capability using the Torx Plus IP25 drive, reducing cam-out and tool wear for efficient installation.
- Exceptional thread-forming performance in non-ferrous metals like aluminum, brass, and copper, eliminating the need for pre-tapped holes.
- Enhanced pull-out and vibration resistance due to the Tri-Lobe shank design, ensuring secure, long-lasting fastening.
- Reliable coarse UNC 10-24 threading provides quick assembly and strong holding power in various material thicknesses.
- Fully threaded blunt tip design allows for consistent engagement and ease of starting in thread-forming applications.
- Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global industrial standards.
Professional Applications & Engineering Value
This zinc-plated steel tapping screw is engineered to address common challenges in fastening aluminum, brass, and copper components, where traditional screws may strip threads or require additional tapping steps. The Tri-Lobe shank and thread-forming design displace material to create strong, permanent threads, reducing assembly time and improving joint integrity. With a Torx Plus drive (IP25/T25), it enables high torque application without slippage, ideal for automated or high-volume production lines. The coarse UNC 10-24 threads and blunt tip ensure easy starts and full engagement, making these screws a reliable choice for HVAC, electronics, and metal fabrication industries where vibration resistance and durability are critical.
Specification Summary & Compliance
This screw features a No. 10-24 UNC coarse thread with a length of 1/2" and tolerance of -0.03" to 0", ensuring precise fit. It conforms to standard thread specifications for thread-forming tapping applications, with a pan head and right-hand threading. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it meets stringent environmental and safety requirements for industrial use.
