- Exceptional mechanical strength with 70,000 psi tensile strength for demanding heavy-duty applications
- Reliable and secure fastening ensured by Class 2A thread fit and UNC coarse threads for easier alignment
- Optimized for high-torque installation with a large 15/16" external hex head for superior grip
- Enhanced durability and wear resistance provided by Rockwell B70 hardness
- Versatile partial threading allows for both clamping and precise positioning over the 12" length
- Full regulatory compliance with ASME B18.2.1, RoHS 3, and REACH for guaranteed quality and safety
Professional Applications & Engineering Value
This 5/8"-11 UNC hex head screw is engineered to solve critical challenges in industrial applications where corrosion resistance and structural integrity are paramount. The 316 stainless steel material provides excellent protection against corrosive agents, making it ideal for marine, chemical processing, and outdoor infrastructure. The coarse thread (UNC) and Class 2A thread fit ensure rapid assembly and reliable performance under vibration, while the external hex drive and large head size facilitate high-torque installation with standard tools. The partially threaded 12-inch design offers a non-threaded shank for precise shear plane control, making this heavy-duty screw a trusted component in structural frameworks, machinery assembly, and construction projects demanding long-term durability.
Specification Summary & Compliance
This fastener adheres to inch system measurements with a 5/8"-11 UNC thread, Class 2A thread fit for standard tolerance, and a 12" length with partial threading. Manufacturing and dimensional specifications strictly conform to ASME B18.2.1. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances and safe for industrial use.
