Professional Applications & Engineering Value
Engineered for industrial applications where vibration resistance and corrosion protection are critical, these 6-32 UNC thread screws with coarse thread spacing excel in machinery, electronic enclosures, and automotive assemblies. The black-oxide alloy steel construction provides superior protection against oxidation while maintaining the high tensile strength needed for structural integrity. The flanged button head design with 5/64" hex drive simplifies installation in confined spaces, reducing assembly time while the fully threaded shank ensures maximum engagement in both thin and thick materials. These rounded head screws deliver reliable performance where appearance and function must coexist.
Specification Summary & Compliance
Manufactured to precise UNC thread standards with Class 3A thread fit for superior dimensional accuracy. Features coarse thread spacing and right-hand threading with complete 5/16" length threading. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The black-oxide surface treatment on alloy steel provides consistent performance meeting industrial fastening requirements.
