S-90465A105 10-32 x 3/4" Coupling Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass construction, ensuring long-term reliability in humid or chemically aggressive environments.
• Precise and secure thread engagement with Class 2B fine threading (UNF 10-32), minimizing the risk of cross-threading and providing a vibration-resistant connection.
• Easy installation and removal thanks to the external hex drive design, allowing for standard wrenching tools and reducing assembly time.
• Extended connection length capability with a 3/4" fully threaded body, ideal for joining long studs or rods in assembly applications.
• Confident global compliance by meeting REACH and RoHS 3 environmental standards, ensuring suitability for regulated industries and international supply chains.
• Durable and non-sparking properties inherent to brass, making it a safe choice for use in potentially explosive or sensitive operational areas.
• Consistent dimensional accuracy with a 3/8" hex width, ensuring compatibility with standard tools and predictable performance in repetitive assemblies.

Professional Applications & Engineering Value

This 10-32 UNF brass coupling nut is engineered to solve critical challenges in assembly and maintenance where corrosion resistance and thread reliability are paramount. The fine threading (UNF) and Class 2B thread fit provide a tighter, more precise connection than coarse threads, significantly reducing the risk of loosening under vibration—a common failure point in machinery, electrical enclosures, and fluid systems. The external hex drive facilitates quick installation in tight spaces, while the fully threaded, 3/4" long body allows for adjustable joining of long studs or threaded rods, commonly needed in framing, supports, and precision equipment. Made from brass, it inherently resists galvanic corrosion and is non-magnetic, making it indispensable in marine, chemical, and electronics applications where material integrity cannot be compromised.

Specification Summary & Compliance

This coupling nut conforms to Unified National Fine (UNF) thread standards with a 10-32 thread size and Class 2B tolerance for consistent, free-running assembly. Dimensional specifications include a 3/4" length and 3/8" hex width. The product is manufactured in compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy, ensuring adherence to stringent environmental and safety regulations for industrial components.
