Key Features & Benefits at a Glance
- Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for marine, chemical, and outdoor applications.
- High tensile strength of 70,000 PSI ensures reliable performance under heavy loads and prevents failure in demanding mechanical assemblies.
- Robust Rockwell B70 hardness provides excellent durability and wear resistance, extending the screw's service life.
- Coarse UNC thread pattern offers faster installation and superior grip in soft materials or where vibration resistance is critical.
- Class 2A thread fit guarantees consistent, easy assembly with standard nuts while maintaining secure fastening.
- External hex drive and hex head design allows for high-torque application with common tools, speeding up installation and removal.
- Full threading along the 3-1/2" length provides maximum engagement and holding power across the entire fastener.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this 5/8"-11 UNC hex head screw in 316 stainless steel addresses critical challenges like corrosion, high stress, and assembly efficiency. The coarse thread design ensures rapid installation and reliable performance in structural frameworks, machinery, and equipment subjected to vibrations. Its fully threaded configuration and external hex drive enable secure fastening in demanding environments such as construction, marine, and chemical processing, reducing maintenance needs and downtime. By combining high tensile strength with corrosion-resistant properties, it provides long-term reliability where standard fasteners might fail, making it a cost-effective solution for B2B procurement in sectors prioritizing durability and compliance.
Specification Summary & Compliance
This screw features a Class 2A thread fit per UNC standards, ensuring precise dimensional accuracy for consistent assembly. It is manufactured in compliance with ASME B18.2.1 specifications for hex head screws and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally sensitive and industrial applications without hazardous substances.
