Gibraltar 41607G Flange Nut 3/4-10 12L14 Steel Black Oxide

Product Description

The GIBRALTAR 41607G is a 3/4-10 threaded flange nut manufactured from Grade 12L14 steel with a black oxide finish. It measures 1-5/8 inches in flange diameter, 1 inch in overall height, and 1/4 inch in flange height, with 1-1/4 inches across the flats. The integrated flange distributes clamping load over a wider bearing surface, reducing the need for a separate washer in many fastening applications. This nut meets TCMAI fastener standards and is suited for mechanical assembly, structural fastening, and equipment fabrication work performed by pipefitters, millwrights, ironworkers, and general maintenance tradespeople.

This flange nut is used in industrial and commercial assembly applications where vibration resistance and load distribution are important. The black oxide finish provides mild corrosion resistance in controlled environments. It is appropriate for use in mechanical equipment frames, HVAC structural supports, plumbing fixture mounting, and general trade fabrication work where a 3/4-10 UNC threaded connection is specified.

Key Features

• 3/4-10 UNC thread for wide compatibility with standard 3/4 inch bolts and studs
• Grade 12L14 steel construction for consistent machinability and reliable strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Integrated flange distributes bearing load, eliminating the need for a separate washer in many applications
• Meets TCMAI fastener standards
• Sold individually, suitable for single-unit replacement or small-quantity service needs

Compatibility

Designed for use with 3/4-10 UNC threaded fasteners in standard inch-measurement mechanical and structural assemblies.

Installation Notes

Installation is performed with a 1-1/4 inch wrench or socket. Ensure the mating bolt or stud thread specification matches 3/4-10 UNC before installation. De-energize and depressurize any system before performing fastener work on live equipment. Do not use this fastener in applications requiring stainless steel or where standing moisture or chemical exposure exceeds the protection level of a black oxide finish.
