Long Nuts
Long Nuts (Coupling / Extension Nuts)
Our Long Nuts, technically known as Coupling Nuts or Extension Nuts, are elongated hexagonal fasteners designed to join two male threads, such as threaded rods or bolts. Essential for structural continuity, they allow for the extension of fastener lengths in hanging systems and leveling applications. Their hexagonal profile ensures easy tightening with standard wrenches, making them a staple in plumbing, construction, and machinery assembly.
