S-91395A210 3/4"-16 Hex Nuts

Key Features & Benefits at a Glance

• Corrosion-resistant fiberglass construction ensures long-lasting performance in harsh environments, reducing replacement frequency and maintenance costs.
• High-temperature tolerance up to 190°F maintains structural integrity in demanding thermal applications without compromising thread fit.
• Precise Class 2B thread fit guarantees smooth assembly and reliable fastening, minimizing the risk of cross-threading or loosening.
• Standard external hex drive design allows for easy installation with common tools, speeding up assembly processes in industrial settings.
• RoHS 3 (2015/863/EU) compliance meets stringent environmental regulations, making it suitable for global supply chains and eco-conscious projects.
• Fine UNC thread spacing (16 TPI) provides superior vibration resistance and load distribution compared to coarse threads.
• Durable gray fiberglass material offers excellent electrical insulation properties, ideal for applications requiring non-conductive fasteners.

Professional Applications & Engineering Value

This 3/4"-16 UNC fiberglass hex nut is engineered to address common industrial challenges such as corrosion, electrical conductivity, and thermal stress. The fiberglass material inherently resists rust and chemical degradation, making it perfect for marine, chemical processing, and outdoor installations where metal fasteners fail. Its Class 2B thread fit ensures consistent engagement with mating components, reducing assembly errors in high-volume production lines. The right-hand fine thread design enhances grip in vibrating machinery, while the external hex drive simplifies maintenance in confined spaces. Ideal for electrical enclosures, HVAC systems, and high-temperature applications up to 190°F, this nut delivers reliable performance without the weight or conductivity issues of traditional metal nuts.

Specification Summary & Compliance

This hex nut adheres to UNC thread standards with a Class 2B thread fit for consistent dimensional accuracy. Key specifications include a 3/4"-16 thread size, 1 1/8" width, and 41/64" height, manufactured under the inch system of measurement. It is fully RoHS 3 (2015/863/EU) compliant, ensuring it meets hazardous substance restrictions for international use. The standard hex nut profile and fine thread spacing align with industrial fastener requirements for reliability and interchangeability.
