Professional Applications & Engineering Value

Engineered for demanding industrial applications, this Grade 8 hex head screw delivers exceptional performance in heavy machinery, structural assemblies, and equipment manufacturing. The steel construction with Rockwell C33 hardness provides outstanding resistance to shear and tensile stresses, while the UNC coarse thread design prevents cross-threading and enables quicker assembly in production environments. The zinc yellow-chromate plating creates a durable barrier against corrosion, making these fully threaded fasteners ideal for outdoor equipment, automotive components, and industrial machinery exposed to moisture and chemicals. With its external hex drive and standardized dimensions, this screw simplifies maintenance and reduces installation time in high-volume manufacturing operations.

Specification Summary & Compliance

This 9/16"-12 UNC hex head screw features Class 2A thread fit tolerance for precise engagement and maintains dimensional accuracy per ASME B18.2.1 specifications. The fastener meets SAE J429 Grade 8 requirements with verified 150,000 psi tensile strength and Rockwell C33 hardness. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance adherence for global industrial applications.
