S-90475A130 3/8"-16 Hex Nuts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel coating, extending service life in harsh industrial environments.
• Space-saving thin profile (7/32" height) allows for use in tight assemblies without compromising strength.
• Reliable coarse threading (UNC 3/8"-16) ensures quick installation and reduced risk of cross-threading in high-vibration applications.
• Precise Class 2B thread fit provides consistent engagement and secure fastening with standard bolts.
• Standard 9/16" hex width offers compatibility with common wrenches for easy manual or tool-driven installation.
• External hex drive design facilitates high-torque application and straightforward removal when maintenance is required.
• Full compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global supply chain requirements.

Professional Applications & Engineering Value

This 3/8"-16 UNC thin hex nut is engineered from black-oxide steel to address common industrial challenges such as corrosion, space constraints, and assembly efficiency. The coarse thread design minimizes galling and allows for rapid installation in machinery, automotive, and structural frameworks, reducing labor time. Its thin profile is ideal for compact assemblies where standard nuts would not fit, while the external hex drive supports high-torque applications without slippage. By combining durable material with precise Class 2B thread fit, this nut delivers reliable performance in heavy-duty and vibration-prone settings, ensuring long-term fastener integrity.

Specification Summary & Compliance

This hex nut adheres to inch system standards with a thread size of 3/8"-16 UNC and Class 2B thread fit for consistent dimensional accuracy. It meets manufacturing specifications for external hex drive and right-hand thread direction, and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are upheld.
