Coupling Nuts Hex Reducing Steel Zinc 1/2-13 X 5/8-11 X 1-1/4 is a durable hex?shaped fastening solution designed to join two threaded rods or studs of different diameters with precision. Crafted from steel and zinc?plated for corrosion resistance, this reducing coupling nut features two internal thread sizes: 1/2-13 and 5/8-11, allowing you to adapt between standard coarse?thread rods with ease.

• Two-thread sizes: 1/2-13 UNC on one end and 5/8-11 UNC on the other end for versatile joining of different rod sizes.
• Material and finish: Steel core with a zinc finish for durability and corrosion resistance.
• Size: Length 1-1/4 inches (overall length).
• Design: Hex coupling nut provides a secure grip for standard wrenches, enabling easy assembly in tight spaces.
• Standards: Compatible with standard UNC threads (coarse thread).

Applications

• Use in electrical, mechanical, and construction projects to connect two threaded rods or studs of differing diameters.
• Ideal for framing, machinery, automotive repairs, and general hardware assembly.

How to use

Align the threads of the two mating rods, thread the reducing coupling nut onto the first rod, then continue threading until the second rod engages. Tighten with a wrench to the required torque. Ensure mating rods have compatible UNC threads and clean the threads before assembly.
