S-1319N11 10-32 x 1 3/4" Coupling Nuts

Key Features & Benefits at a Glance

• Superior thermal resistance - withstands continuous operation up to 250°F without compromising structural integrity
• Exceptional connection length - 1 3/4" extra long profile provides maximum thread engagement for secure, vibration-resistant joints
• Precision thread compatibility - 10-32 UNF fine threading with Class 2B fit ensures smooth assembly and reliable torque transmission
• Chemical and corrosion resistance - Nylon 6/6 construction offers excellent protection against moisture, oils, and industrial chemicals
• Lightweight electrical insulation - plastic composition prevents electrical conductivity while reducing overall assembly weight
• Enhanced installation control - 5/8" external hex drive allows for standard tooling and consistent torque application
• Regulatory compliance assurance - meets REACH and RoHS 3 environmental standards for global industrial applications

Professional Applications & Engineering Value

This Nylon 6/6 plastic coupling nut delivers critical performance advantages in demanding environments where metal fasteners fall short. The extra long 1 3/4" design provides extended thread engagement for connecting threaded rods or studs in electrical enclosures, machinery guards, and instrumentation panels where vibration resistance is paramount. The partially threaded configuration with 10-32 UNF fine threading ensures precise alignment while the Class 2B thread fit maintains consistent clamping force without galling. As a non-conductive, corrosion-resistant alternative to metal fasteners, it eliminates galvanic corrosion concerns in mixed-material assemblies and provides reliable performance in high-temperature applications up to 250°F. The off-white nylon construction offers excellent UV resistance for both indoor and outdoor industrial settings.

Specification Summary & Compliance

This coupling nut features 10-32 UNF fine threading with Class 2B thread fit per UNF standards, ensuring precise dimensional accuracy and reliable performance. The partially threaded, right-hand configuration provides optimal engagement with standard 5/8" external hex drive for consistent installation. Manufactured from Nylon 6/6 plastic with 1/2" minimum thread length and 1 3/4" overall length, this component is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, making it suitable for global industrial applications requiring stringent material compliance.
