Gibraltar 41807G Spherical Flange Nut 3/4-10 Steel Black Oxide

Product Description

The GIBRALTAR 41807G is a 3/4-10 spherical flange nut manufactured from 12L14 steel with a black oxide finish. The spherical bearing surface under the flange distributes clamping load evenly and self-aligns to compensate for slight angular misalignment between mating surfaces. The integrated flange eliminates the need for a separate washer, making it a practical choice for structural fastening applications. At 1 inch tall with a 1-5/8 inch flange diameter and a 1/4 inch flange height, this nut is sized for medium to heavy fastening work. Machinists, millwrights, and maintenance technicians commonly install this type of hardware in equipment assemblies, fixtures, and fabricated structures.

The 41807G is suited for use in industrial, commercial, and manufacturing environments where vibration or slight surface irregularities require a self-seating fastener. The black oxide coating provides a degree of corrosion resistance and reduces light glare on exposed hardware. This nut is appropriate for use with 3/4-10 UNC threaded rod, bolts, or studs in both original equipment and repair applications. The 1-1/4 inch hex size is compatible with standard industrial wrenches and torque tools.

Key Features

• Spherical flange bearing surface self-aligns to compensate for angular misalignment
• Integrated flange replaces the need for a separate flat washer
• 12L14 steel grade provides good machinability and consistent thread quality
• Black oxide finish for moderate corrosion resistance and reduced surface glare
• Meets TCMAI standards
• 1-1/4 inch hex size fits standard industrial drive tools

Compatibility

Designed for use with 3/4-10 UNC threaded fasteners including bolts, cap screws, and threaded rod in industrial and commercial mechanical assemblies.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or qualified mechanical tradespeople. Ensure the mating threaded fastener is clean and free of debris before threading the nut. The spherical flange should seat flush and fully against the mating surface before applying final torque with an appropriately rated torque wrench. Do not exceed the rated load capacity of the fastener assembly.
