Metal Nuts

Coupling Nuts

Coupling nuts are elongated internally threaded fasteners engineered specifically to join two external machine threads, such as threaded rods, studs, or piping. Their extended hexagonal body allows for greater thread engagement length, significantly distributing tensile load and minimizing the risk of thread stripping or galling under high-stress conditions. Manufactured to standards like ASTM A563, they are vital components in structural tie rod systems, heavy HVAC suspension systems, and industrial machinery where precise distance adjustments and rod extensions are required.
