S-90475A033 1/2"-20 Hex Nuts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance from the black-oxide steel finish, extending service life in demanding industrial environments.
• Space-saving thin profile (3/16" height) for applications where clearance is limited without sacrificing strength.
• Reliable fine thread engagement with 1/2"-20 UNF Class 2B threads, providing vibration resistance and secure fastening.
• Easy installation and removal using standard tools with the external hex drive style, improving assembly efficiency.
• Consistent dimensional accuracy with a 3/4" width, ensuring compatibility and interchangeability in inch-based assemblies.
• Compliance with major environmental regulations (RoHS 3 & REACH), making it suitable for global supply chains and sensitive applications.
• Durable steel construction offers high tensile strength for long-term performance in mechanical and structural applications.

Professional Applications & Engineering Value

This 1/2"-20 UNF thin hex nut is engineered to address common challenges in precision assembly, such as vibration-induced loosening and corrosion in harsh environments. The black-oxide steel material provides a protective layer that significantly reduces oxidation, making it ideal for automotive, machinery, and outdoor equipment where exposure to moisture and chemicals is a concern. Its fine UNF threads and Class 2B thread fit ensure tight, secure connections that maintain integrity under dynamic loads, minimizing the need for frequent maintenance. The thin profile allows for use in compact spaces, such as electronic enclosures or tight-tolerance mechanical systems, without compromising on the robustness expected from industrial hex nuts. By combining precise inch system dimensions with a right-hand thread direction, this nut streamlines installation processes, reducing labor time and enhancing overall project efficiency in B2B procurement scenarios.
