Long Nut

🔩 Long Nut (Coupling Nut / Extension Nut)

(Thread Extension & Rod Coupling Solution for Structural and Mechanical Applications)

Neo Fasteners manufactures and supplies high-quality Long Nuts, also known as Coupling Nuts or Extension Nuts, designed to join two externally threaded components—typically threaded rods, studs, or bolts. These elongated hex nuts provide a secure and extended thread engagement, making them ideal for structural steelwork, suspended systems, foundation anchors, and mechanical assemblies.

🔹 Product Overview:

Long Nuts are internally threaded, elongated hex nuts that allow precise alignment and tightening of two male-threaded fasteners. Their extended body ensures strong axial clamping, and they are often used where length adjustment, rod coupling, or thread repair is needed. Available in a wide range of materials, sizes, and finishes, Neo Fasteners’ Long Nuts ensure durable performance under mechanical and environmental stresses.
