Professional Applications & Engineering Value
This 9/16"-12 UNC hex head screw in 18-8 Stainless Steel is engineered to address critical industrial fastening challenges, including corrosion, high stress, and repetitive maintenance. The coarse thread design ensures rapid installation in structural applications, while the partial threading provides controlled clamp load distribution, reducing the risk of material damage. With its external hex drive, it delivers superior torque transmission for heavy machinery, construction equipment, and marine applications where 80,000 PSI tensile strength and consistent performance are non-negotiable. The stainless steel material inherently resists oxidation and chemical exposure, making it a reliable choice for outdoor, chemical processing, and food-grade environments.
Specification Summary & Compliance
This fastener meets ASME B18.2.1 specifications for dimensional accuracy and performance. Threads conform to UNC coarse thread standards with a Class 2A fit for consistent engagement. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for global industrial supply chains.
