Professional Applications & Engineering Value
This Grade 5 zinc-plated steel hex head screw delivers critical engineering solutions for industrial applications where vibration resistance and structural integrity are paramount. The UNC coarse thread configuration prevents cross-threading during high-speed assembly while maintaining strong holding power in steel-to-steel connections. The partially threaded shank design concentrates clamping force precisely where needed, making it ideal for machinery, structural frameworks, and heavy equipment where precise load distribution is essential. The zinc plating provides sacrificial corrosion protection, significantly extending service life in environments exposed to moisture and industrial chemicals. With its external hex drive and flanged design, this fastener streamlines installation while providing reliable performance in demanding applications.
Specification Summary & Compliance
This 1/2"-13 hex head screw features Class 2A thread fit per UNC standards with precise dimensional accuracy. Manufactured to meet IFI 111/SAE J429 specifications for Grade 5 fasteners, ensuring consistent quality and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict regulatory adherence.
