Professional Applications & Engineering Value

These Type B thread forming screws deliver exceptional performance in sheet metal applications where reliable fastening is critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the thread forming design eliminates the need for tapping operations, reducing assembly time and labor costs. The Phillips flat head with 82° countersink angle ensures smooth, flush surfaces that won't interfere with adjacent components. Engineered with a blunt tip and precise threading, these screws prevent material splitting and maintain structural integrity in thin-gauge metals. The combination of No. 2 Phillips drive and optimized thread geometry ensures secure installation without stripping, making them ideal for high-volume production lines and maintenance applications requiring dependable, long-lasting fasteners.
