Professional Applications & Engineering Value
This 7/8"-14 UNF hex head screw is engineered to address critical challenges in heavy machinery, construction, and marine equipment where corrosion resistance and high tensile strength are paramount. The 18-8 Stainless Steel material combats rust and chemical exposure, while the UNF fine thread and Class 2A thread fit ensure precise, vibration-resistant fastening in dynamic loads. Its partially threaded design concentrates clamping force, preventing joint loosening in structural applications. With an external hex drive, it supports efficient installation in confined spaces, making it a reliable choice for industrial-grade assemblies demanding longevity and regulatory compliance.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit for consistent dimensional accuracy and UNF (Unified National Fine) thread standards with a 7/8"-14 thread size. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
