Professional Applications & Engineering Value
This 5/16"-18 UNC hex head screw in 316 stainless steel is engineered to solve critical challenges in demanding industrial settings. Its exceptional corrosion resistance makes it ideal for marine, chemical processing, and food industry applications where exposure to moisture and aggressive substances is common. The coarse thread design and partial threading provide superior holding power and reduce the risk of cross-threading during assembly, while the external hex drive allows for high-torque installation with standard tools. With a 70,000 psi tensile strength and Rockwell B70 hardness, it maintains structural integrity under heavy loads and vibration, ensuring long-term reliability in machinery, structural frameworks, and equipment manufacturing where failure is not an option.
Specification Summary & Compliance
This inch-system fastener features precise Class 2A thread fit with UNC coarse threading (5/16"-18) and partial threading up to a minimum of 7/8". Manufactured in compliance with ASME B18.2.1 specifications for dimensional accuracy and performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries worldwide.
