Gibraltar 41507G Coupling Nut 3/4-10 Unc Steel Black Oxide

Product Description

The GIBRALTAR 41507G is a standard coupling nut designed to join two threaded rods or bolts with matching 3/4-10 UNC right-hand thread. Machined from 1117 steel and finished with a black oxide coating, this coupling nut provides corrosion resistance and meets TCMAI standards. It measures 1-7/8 inches overall length with a 1-1/4 inch width across flats, weighing 0.54 pounds. Electricians, plumbers, HVAC technicians, and general contractors use coupling nuts to extend threaded rod assemblies in structural, mechanical, and utility installations.

This coupling nut is suited for residential and commercial applications where threaded rod extension or fastener joining is required. Common installations include equipment support rods, pipe hanger assemblies, ductwork supports, and panel or structural bracing. The 3/4-10 UNC thread standard is widely used in mechanical and construction trade work, making this a frequent stock item for service trucks and job-site fastener kits.

Key Features

• 3/4-10 UNC right-hand thread for standard compatibility with threaded rod and fastener assemblies
• Black oxide coating provides mild corrosion resistance in dry and low-humidity environments
• 1117 steel construction delivers solid mechanical strength for structural and support applications
• 1-7/8 inch overall length with 1-1/4 inch width across flats for standard wrench fitment
• Meets TCMAI standards for dimensional and material compliance

Compatibility

Designed as an OEM-style replacement and standard coupling nut for 3/4-10 UNC threaded rod and bolt applications in mechanical, plumbing, HVAC, and electrical support installations.

Installation Notes

Installation requires a wrench sized for 1-1/4 inch width across flats. Power down or de-energize any nearby electrical equipment before working in panel or equipment areas. Thread engagement should cover the full interior length of the nut on both joined fasteners. Verify that mating threads are clean and free of damage before assembly to ensure proper load transfer.
