Professional Applications & Engineering Value
These 3-48 UNC zinc-plated steel rounded head screws deliver exceptional engineering value in industrial settings where corrosion resistance and high tensile strength are critical. The zinc-plated coating protects against rust and oxidation in humid or outdoor environments, while the fully threaded coarse UNC design ensures rapid assembly and strong holding power in metal, plastic, and composite materials. The Phillips drive and pan head profile allow for flush mounting and easy torque application, reducing installation errors in automated or manual assembly lines. Ideal for machinery, electrical enclosures, and equipment manufacturing, these screws solve common fastening challenges like vibration loosening and material degradation, providing long-term reliability with ASME B18.6.3 compliance for precision and safety.
Specification Summary & Compliance
These screws feature Class 2A thread fit for standard tolerance and easy assembly, with UNC coarse threads (3-48 size) and right-hand threading. Manufacturing adheres to ASME B18.6.3 specifications for dimensional accuracy and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance-free composition for global industrial use.
