- External hex drive enables easy installation and removal with standard tools, improving assembly efficiency.
Professional Applications & Engineering Value
This 1"-8 UNC hex head screw is engineered to address common industrial challenges, such as corrosion-induced failure and vibration loosening. Constructed from 18-8 stainless steel, it resists rust and chemical exposure in environments like marine, chemical processing, and outdoor infrastructure. The coarse thread and Class 2A fit ensure quick, reliable fastening in soft materials or where alignment variations occur, reducing installation time and rework. With a fully threaded body and external hex drive, it provides uniform clamping force and easy access in confined spaces, making it ideal for heavy machinery, structural assemblies, and equipment requiring high tensile strength and long-term reliability.
Specification Summary & Compliance
This screw adheres to ASME B18.2.1 standards, ensuring dimensional accuracy and performance consistency. It features a Class 2A thread fit with UNC coarse threading for reliable engagement. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), it meets environmental and safety regulations for industrial use.
