Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and reducing maintenance costs.
- High tensile strength of 70,000 psi ensures reliable load-bearing capacity and structural integrity in demanding applications.
- Rockwell B70 hardness provides superior durability and resistance to wear, extending the fastener's service life.
- Class 2A thread fit offers easier assembly and consistent performance with standard nuts and tapped holes.
- Coarse UNC thread design enables quick installation and better resistance to vibration loosening.
- External hex drive and hex head allow for high-torque application with common tools, speeding up assembly processes.
- Partial threading provides unthreaded shank for precise clamping and shear strength in structural connections.
Professional Applications & Engineering Value
This 5/8"-11 UNC hex head screw is engineered to address critical challenges in industrial settings, such as corrosion, high stress, and assembly efficiency. The 18-8 Stainless Steel material combats rust and chemical exposure, making it suitable for outdoor, marine, and chemical processing equipment. With a coarse thread and Class 2A thread fit, it ensures rapid, secure fastening in heavy machinery, construction frameworks, and transportation systems, minimizing downtime. The partially threaded design enhances clamping force and prevents joint failure, while the external hex drive supports high-torque tools for robust installations. Ideal for applications requiring ASME B18.2.1 compliance, this screw delivers consistent performance in industrial hex screw assemblies, reducing the risk of fastener fatigue and improving overall system reliability.
Specification Summary & Compliance
This product adheres to precise dimensional standards, including a Class 2A thread fit for consistent engagement and UNC coarse threads with a size of 5/8"-11. It meets ASME B18.2.1 specifications for hex head screws, ensuring interoperability and safety. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms environmental and health safety, free from restricted substances, supporting sustainable procurement in industrial sectors.
