Hex Coupling Nuts

Coupling nuts, also known as extension nuts, are threaded fasteners used for joining two male threaded rods. The exterior of this threaded fastener is typically a hex, allowing a wrench to easily hold it. Threaded coupling nuts can also be round with one or more flats. We offer a variety of hex and round coupling nuts in a range of metric and inch sizes.
