Professional Applications & Engineering Value
This 7/16-20 UNF hex head screw is engineered to solve critical fastening challenges in demanding sectors such as marine, chemical processing, and outdoor infrastructure. The core of its value lies in the 316 Stainless Steel material, which offers enhanced resistance to chlorides and acidic agents, preventing premature failure in corrosive environments. The fine UNF thread and Class 2A fit work in tandem to provide a precise, vibration-resistant connection that maintains integrity under dynamic loads. Combined with a high 70,000 psi tensile strength and Rockwell B70 hardness, this fully threaded fastener delivers reliable, long-term performance where failure is not an option, ensuring operational continuity and reducing maintenance cycles.
Specification Summary & Compliance
This product adheres to ASME B18.2.1 specifications, ensuring dimensional accuracy and interchangeability. The UNF fine thread features a Class 2A tolerance for a consistent, reliable fit. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industries.
