Professional Applications & Engineering Value
These zinc-plated steel rounded head screws deliver exceptional engineering value in industrial fastening applications where corrosion resistance and high tensile strength are critical. The 10-32 UNC fine threading provides superior grip in materials requiring precise thread engagement, while the fully threaded design ensures consistent clamping force across the entire 3 1/4" length. The Phillips drive system with No. 2 size offers efficient installation in automated or manual assembly processes, and the rounded pan head profile creates a low-profile finish that minimizes snagging in machinery and equipment. These screws effectively address common industrial challenges including vibration resistance, environmental exposure, and the need for reliable, repeatable fastening solutions in manufacturing, machinery assembly, and structural applications.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 specifications, these screws feature Class 2A thread fit for precision tolerance and reliable performance. The UNC thread form with fine spacing ensures optimal engagement in various materials. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and safety standards. The combination of zinc-plated steel construction, 60,000 psi tensile strength, and Rockwell B70 hardness provides a comprehensive solution for industrial fastening requirements where quality assurance and regulatory compliance are paramount.
