Professional Applications & Engineering Value
Engineered for demanding industrial assembly, these 12-24 UNC zinc-plated steel screws address critical challenges in machinery, equipment manufacturing, and structural applications. The coarse thread design provides superior holding power in softer materials and resists vibration loosening, while the fully threaded construction ensures maximum engagement in varied material thicknesses. The combination of Rockwell B70 hardness and 60,000 psi tensile strength makes these rounded head Phillips screws ideal for applications requiring repeated disassembly and reassembly without thread degradation. The zinc-plated finish offers essential corrosion protection in environments with moderate exposure to moisture and chemicals, extending maintenance intervals and reducing lifecycle costs.
Specification Summary & Compliance
This 7/8" length screw features Class 2A thread fit per UNC standards with precise dimensional accuracy. Manufactured to ASME B18.6.3 specifications for consistent quality and performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries.
