Key Features & Benefits at a Glance
- Exceptional corrosion resistance thanks to 316 Stainless Steel construction, ideal for harsh environments and chemical exposure
- High tensile strength of 70,000 psi ensures reliable performance under heavy loads and in demanding structural applications
- Superior durability and wear resistance provided by a Rockwell B70 hardness rating for extended service life
- Easy installation and removal with a standard external hex drive and 15/16" head width for common wrench compatibility
- Secure and precise thread engagement with a Class 2A UNC coarse thread fit, reducing cross-threading risks
- Full-length threading offers maximum grip and holding power along the entire 3/4" shank length
- Compliance with major industry standards including 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 and marine settings where corrosion resistance and structural integrity are paramount. The 316 Stainless Steel material provides excellent protection against rust and chemical degradation, making it ideal for offshore platforms, chemical processing equipment, and food-grade machinery. The coarse UNC thread and Class 2A fit ensure quick assembly and reliable fastening in high-vibration environments, while the external hex drive allows for high-torque installation with standard tools. Its fully threaded design maximizes load distribution, preventing joint failure in heavy-duty construction, transportation, and infrastructure projects where long-term reliability is non-negotiable.
Specification Summary & Compliance
This screw features a 5/8"-11 UNC coarse thread with a Class 2A thread fit for standard inch-system applications, ensuring dimensional accuracy and interchangeability. It is manufactured in compliance with the ASME B18.2.1 standard for hex head screws and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial use without hazardous substances.
