Professional Applications & Engineering Value

This extra long coupling nut delivers exceptional engineering value in applications requiring extended reach between threaded components. The zinc-plated steel construction provides superior corrosion protection, making it ideal for outdoor equipment, structural frameworks, and industrial machinery exposed to moisture and harsh conditions. The 4" length solves critical spacing challenges in construction, manufacturing, and assembly operations where standard nuts cannot bridge the required distance. With its external hex drive and coarse UNC threading, this coupling nut enables rapid installation and removal while maintaining high torque capacity. The partially threaded design offers versatility for precise positioning and adjustment in complex mechanical systems, reducing assembly time and improving overall system reliability.

Specification Summary & Compliance

This coupling nut features precise 3/8"-16 UNC coarse threading with Class 2B thread fit for consistent engagement and reliable performance. Manufactured to industry standards for external hex drive coupling nuts, it maintains dimensional accuracy throughout its 4" length and 3/4" width. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and meeting the latest substance restriction requirements for industrial fasteners.
