Professional Applications & Engineering Value
This 18-8 Stainless Steel Hex Head Screw is engineered to address critical challenges in industrial assembly, such as vibration resistance and environmental degradation. The UNF fine thread and Class 2A fit provide superior clamping force and prevent back-off in dynamic applications, from heavy machinery to structural frameworks. Its corrosion-resistant properties make it suitable for chemical processing, marine, and food-grade equipment, where moisture and corrosive agents are prevalent. The combination of 80,000 psi tensile strength and a robust external hex drive ensures that these screws can be torqued to precise specifications without stripping, delivering long-term reliability and reducing maintenance cycles in demanding B2B environments.
Specification Summary & Compliance
This screw adheres to precise dimensional standards with a Class 2A thread fit and UNF 1/2"-20 thread specification. Manufacturing and material quality comply with ASME B18.2.1, ensuring consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility for global industrial supply chains.
