Reducing Rod Coupler Nuts

Reducing rod couplers, or coupling nuts are used to connect all thread or other threaded hardware of different sizes. For instance, if you have a 1/2" piece of all thread and you want to drop down to 3/8", simply screw on the appropriate reducing rod coupler or nut. We stock reducing rod couplers in 3/8"-16 to 1/4"-20, 1/2"-13 to 3/8"-16 and 5/8"-11 to 1/2"-13.
