Professional Applications & Engineering Value
These 2-56 UNC zinc-plated steel rounded head screws deliver exceptional engineering value in industrial and commercial applications where reliability is critical. The zinc-plated steel construction provides robust corrosion protection, making them ideal for machinery, equipment assembly, and electronic enclosures exposed to harsh conditions. With coarse UNC threading and Class 2A thread fit, they ensure rapid installation and secure fastening in metals, plastics, and composite materials, reducing assembly time and minimizing loosening risks. The pan head profile and Phillips drive facilitate easy access in confined spaces while maintaining a low-profile appearance. Engineered to meet ASME B18.6.3 standards, these screws offer consistent dimensional accuracy and performance for OEM and MRO applications requiring heavy-duty fastening solutions.
Specification Summary & Compliance
These screws feature precise Class 2A thread fit per UNC standards with a diameter of 0.086" and 1 1/4" length. Manufacturing complies with ASME B18.6.3 specifications for dimensional consistency. Environmental and safety compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring hazardous substance restrictions are met for global industrial use.
