S-95010A160 5/8"-11 ASME B18.2.2 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional strength and reliability with ASTM Grade 2H steel construction, ensuring secure, long-lasting fastening in demanding applications
• Superior wrench engagement and torque transmission from the extra-wide thin profile, reducing the risk of rounding and tool slippage
• Precise and reliable thread engagement with Class 2B thread fit, minimizing cross-threading and ensuring consistent assembly quality
• Broad compatibility and easy installation with standard 5/8"-11 UNC coarse threads and right-hand direction, fitting common industrial bolts
• Guaranteed dimensional consistency and interchangeability by conforming to the rigorous ASME B18.2.2 standard
• Safe for use in regulated environments as it is fully compliant with RoHS 3 and REACH environmental directives
• Optimized for space-constrained applications with a low 23/64" height profile while maintaining a robust 1 1/16" width for ample gripping surface

Professional Applications & Engineering Value

This 5/8"-11 UNC hex nut is engineered to solve critical challenges in heavy-duty industrial applications. The ASTM Grade 2H steel provides a high proof load capacity, preventing failure under extreme vibration and tensile stress. Its extra-wide thin profile offers a larger wrench flat surface, which is crucial for applying high torque without deforming the nut, a common issue in maintenance and construction. The coarse thread (UNC) design is highly resistant to fouling and cross-threading, making it ideal for rapid assembly in harsh environments like structural steelwork, heavy machinery, and transportation equipment. This combination of material strength and intelligent profile design delivers reliable performance where fastener integrity is non-negotiable.
