Professional Applications & Engineering Value
These 2-56 UNC coarse thread Phillips pan head screws are engineered to address critical fastening challenges in precision machinery, electronics, and automotive assemblies. The zinc-plated steel construction provides a protective barrier against oxidation and chemical exposure, extending service life in demanding conditions. With fully threaded design and Class 2A thread fit, these screws deliver consistent clamping force and vibration resistance, preventing loosening in dynamic applications. The coarse UNC thread facilitates quick installation in various materials, while the pan head profile offers a low-profile finish that doesn't interfere with adjacent components. Ideal for industrial fasteners requiring reliable performance under 60,000 psi tensile loads.
Specification Summary & Compliance
This 1" length screw features 2-56 UNC coarse threads with Class 2A tolerance for precision fit. Manufactured to ASME B18.6.3 specifications, it ensures dimensional accuracy and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict material restrictions.
