Professional Applications & Engineering Value
These 2-56 UNC zinc-plated steel screws deliver exceptional engineering value across industrial applications where corrosion resistance and mechanical reliability are paramount. The coarse thread design provides superior holding power in softer materials and faster installation times, while the rounded pan head profile with slotted drive ensures compatibility with standard tooling. Engineered with fully threaded construction, these fasteners distribute stress evenly, preventing localized failure points in electronic enclosures, light machinery assemblies, and precision equipment. The combination of 60,000 psi tensile strength and Rockwell B60 hardness ensures these screws maintain clamping force under vibration and thermal cycling, solving common loosening and degradation issues in industrial environments.
Specification Summary & Compliance
These rounded head screws feature precise Class 2A thread fit per UNC standards with 3/16" length and 0.167" head diameter. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in global markets. The right-hand thread direction and coarse thread spacing provide optimal engagement characteristics for industrial fastening applications.
