Professional Applications & Engineering Value
Engineered for demanding industrial environments, these zinc-plated steel rounded head screws deliver exceptional performance where reliability matters most. The combination of 60,000 PSI tensile strength and Rockwell B70 hardness ensures these fasteners withstand substantial mechanical stress in heavy machinery, construction equipment, and manufacturing assemblies. The fully threaded UNC coarse spacing provides maximum thread engagement in various materials, while the Phillips/Slotted drive system offers installation flexibility across different work environments. The zinc plating creates a protective barrier against corrosion, making these 10-24 screws ideal for outdoor equipment, electrical enclosures, and industrial maintenance applications where environmental factors would compromise ordinary fasteners.
Specification Summary & Compliance
