Professional Applications & Engineering Value
This 5/16"-18 UNC hex head screw delivers exceptional engineering value through its 18-8 stainless steel composition and coarse thread design. The material's inherent corrosion resistance makes it perfect for outdoor equipment, marine applications, and chemical processing facilities where moisture exposure is common. The fully threaded configuration ensures maximum engagement in both thick materials and assemblies requiring uniform clamping force. With 80,000 PSI tensile strength and Rockwell B70 hardness, this fastener maintains structural integrity in vibration-prone machinery and heavy-load scenarios. The external hex drive provides reliable torque transmission for secure installations in confined spaces, while the Class 2A thread fit guarantees compatibility with standard UNC threaded components across industrial equipment and structural frameworks.
Specification Summary & Compliance
This hex head screw features precise 5/16"-18 UNC coarse threading with Class 2A thread fit tolerance for consistent performance. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety and regulatory adherence for industrial applications. Manufactured to inch system specifications with 5½" length and fully threaded design, this component delivers reliable fastening performance across various engineering requirements.
