S-94805A228 9/16"-18 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments including marine and chemical processing.
• Space-saving thin profile (5/16" height) allows for use in compact assemblies where standard nuts won't fit.
• Precise and reliable fastening ensured by the Class 2B thread fit, providing consistent clamp load and vibration resistance.
• Enhanced grip and torque application from the 7/8" external hex drive, facilitating easier installation with standard tools.
• Fine thread (UNF 18 TPI) advantage offers improved adjustment precision and superior resistance to loosening under dynamic loads.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global markets.
• Right-hand thread design provides standard, intuitive installation for efficient assembly line operations.

Professional Applications & Engineering Value

This 9/16"-18 UNF thin hex nut is engineered to address critical challenges in demanding sectors. Its 316 stainless steel composition delivers exceptional corrosion resistance, making it a top choice for marine equipment, chemical processing plants, and food machinery where exposure to moisture and aggressive agents is common. The fine UNF thread and Class 2B thread fit ensure a tight, secure connection that minimizes the risk of vibration-induced loosening in dynamic applications such as automotive assemblies, precision machinery, and heavy equipment. The thin profile is particularly valuable in space-constrained designs, allowing engineers to maintain structural integrity without compromising on assembly density. This nut provides reliable, long-term performance, reducing maintenance needs and downtime in industrial operations.
