Professional Applications & Engineering Value
This 9/16-18 UNF hex head screw in 18-8 stainless steel is engineered to address critical industrial challenges, such as corrosion in marine, chemical, or outdoor settings. The fine UNF thread and Class 2A fit ensure tight, vibration-resistant connections in machinery, structural assemblies, and heavy-duty equipment. Its partially threaded design allows the unthreaded portion to act as a precise dowel, minimizing shear stress and improving joint stability. With an external hex drive, it supports high-torque applications, reducing the risk of stripping and enhancing efficiency in maintenance or production lines. Compliant with RoHS and REACH, it meets stringent environmental standards, making it a reliable choice for OEMs and MRO operations demanding durability and regulatory conformity.
Specification Summary & Compliance
This screw adheres to UNF fine thread standards with a Class 2A thread fit for consistent dimensional accuracy. Key specifications include a 9/16"-18 thread size, 2-1/4" length, and partial threading. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for international industrial use.
