Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this 5/8"-11 UNC rounded head hex screw delivers critical performance where reliability is non-negotiable. The 18-8 stainless steel material combined with a passivated finish resists corrosion in demanding environments such as chemical processing, marine equipment, and outdoor machinery. Its coarse UNC threading and Class 3A thread fit ensure secure fastening even under high vibration, preventing loosening in dynamic assemblies. The 3/8" hex drive allows for high-torque installation, making it suitable for structural frameworks, heavy machinery, and construction projects where 70,000 psi tensile strength is required to maintain joint integrity under extreme loads.
Specification Summary & Compliance
This fully threaded screw features precise UNC 5/8"-11 coarse threading with Class 3A thread fit for superior dimensional accuracy. Manufactured in compliance with ASME B18.3 specifications, it ensures consistent performance and interchangeability. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for industrial use.
