Professional Applications & Engineering Value
These zinc-plated steel rounded head screws with 2-56 UNC coarse threading are engineered to address common industrial fastening challenges where vibration resistance and corrosion protection are critical. The combination of 60,000 PSI tensile strength and Rockwell B70 hardness makes them ideal for applications in electronics assembly, machinery components, and automotive subsystems where fully threaded fasteners prevent loosening under dynamic loads. The Phillips No. 1 drive ensures efficient installation in confined spaces, while the zinc plating provides a sacrificial layer that significantly extends service life in humid or chemically aggressive environments, reducing maintenance frequency and replacement costs.
Specification Summary & Compliance
These rounded head screws feature precise Class 2A thread fit per UNC standards with 3/8" length and coarse thread spacing for optimal engagement. Manufacturing adheres to ASME B18.6.3 specifications for dimensional accuracy and performance consistency. The products 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.
