Professional Applications & Engineering Value
This 5/16"-18 UNC hex head screw in 316 stainless steel is engineered to solve critical challenges in corrosive and high-stress environments. The coarse thread design prevents cross-threading and ensures rapid assembly, while the fully threaded shank maximizes shear strength in structural applications. Its exceptional corrosion resistance makes it ideal for chemical processing, marine equipment, and food-grade machinery where exposure to chlorides and acids is common. The external hex drive and standardized dimensions provide reliable torque transmission, reducing installation errors in industrial maintenance, construction, and OEM manufacturing. With its 70,000 psi tensile strength, this fastener maintains integrity under vibration and thermal cycling, delivering long-term reliability in heavy-duty assemblies.
Specification Summary & Compliance
This fastener features a 5/16"-18 UNC coarse thread with Class 2A dimensional accuracy, ensuring proper fit with standard nuts. Manufactured to ASME B18.2.1 specifications, it guarantees interchangeability and performance consistency. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious supply chains. Mechanical properties include a Rockwell B70 hardness and 70,000 psi minimum tensile strength, validating its use in critical engineering applications.
