S-90264A701 1 1/8"-7 x 7 1/2" Coupling Nuts

Key Features & Benefits at a Glance

• Exceptional Length for Extended Reach: 7 1/2" extra long profile enables connection of long rods or studs over significant distances, ideal for complex assemblies.
• Superior Corrosion Resistance: Zinc-plated steel construction provides a durable protective barrier, extending service life in harsh or outdoor industrial environments.
• Reliable, High-Strength Fastening: Manufactured from robust steel, this nut is built to withstand high tensile and shear loads in heavy-duty applications.
• Precision Thread Engagement: 1 1/8"-7 UNC coarse threads with a Class 2B fit ensure smooth, accurate assembly and reduced risk of cross-threading.
• Secure and Efficient Installation: The external hex drive style allows for high-torque application using standard wrenches, speeding up assembly times.
• Versatile Threading Design: Partially threaded and right-hand direction offers flexibility for various connection and adjustment scenarios.
• Compliant with Global Standards: Meets RoHS 3 and REACH environmental regulations, ensuring safety and unrestricted use in regulated markets.

Professional Applications & Engineering Value

This extra long coupling nut is engineered to solve critical challenges in structural and mechanical systems where standard nuts fall short. Its substantial 7 1/2" length is indispensable for joining long threaded rods in construction, creating adjustable tie-rod assemblies in machinery, or providing extended connections in framework and scaffolding. The zinc-plated steel material combats corrosion, a common failure point in industrial settings, thereby reducing maintenance frequency and downtime. The 1 1/8"-7 UNC coarse thread and Class 2B fit are specifically chosen for their ability to handle high loads while allowing for quicker assembly compared to fine threads, making them a reliable and efficient choice for heavy-duty industrial applications.

Specification Summary & Compliance

This coupling nut conforms to Unified Coarse (UNC) thread standards with a precision Class 2B thread fit, ensuring dimensional accuracy and reliable performance. Key dimensions include a 1 1/8"-7 thread size and a 1 3/4" width across flats. The product is manufactured to be fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its adherence to strict environmental and safety standards for industrial components.
