Gibraltar 41707G Flange Nut 3/4-16 Black Oxide Steel

Product Description

The GIBRALTAR 41707G is a 3/4-16 flange nut manufactured from Grade 12L14 steel with a black oxide finish. It measures 1 inch in height, features a 1-5/8 inch flange diameter, a 1/4 inch flange height, and 1-1/4 inch width across flats. The integrated flange distributes clamping load over a wider bearing surface, reducing the need for a separate washer. This nut is used in mechanical assemblies, equipment fabrication, and structural fastening applications where a secure, vibration-resistant connection is required. Installation is typically performed by machinists, millwrights, or maintenance technicians.

The GIBRALTAR 41707G suits industrial and commercial fastening applications where a unified inch thread standard is specified. The 3/4-16 fine thread pitch provides increased thread engagement and improved resistance to loosening under dynamic or vibration loads. The black oxide finish offers mild corrosion resistance and reduces light reflection on exposed hardware. This nut is appropriate for use in fabrication shops, production machinery, and general mechanical assembly where Grade 12L14 steel fasteners meet design requirements. It conforms to TCMAI fastener standards.

Key Features

• 3/4-16 unified fine thread for increased thread engagement and vibration resistance
• Grade 12L14 steel construction for consistent machinability and reliable strength
• Black oxide finish provides mild corrosion resistance and a low-reflectance surface
• Integrated 1-5/8 inch flange distributes load and eliminates the need for a separate washer
• Conforms to TCMAI fastener standards for dimensional consistency
• Compact 1 inch height suits tight-clearance assembly locations

Compatibility

Designed as an OEM-style replacement or standard-fit flange nut for mechanical assemblies specifying a 3/4-16 unified fine thread, Grade 12L14 steel, and TCMAI-compliant fastener dimensions.

Installation Notes

Installation is performed by qualified machinists, millwrights, or maintenance technicians using appropriately sized hand tools or powered fastening equipment. Always de-energize and lock out equipment before servicing mechanical assemblies. Use a torque wrench sized for the 1-1/4 inch across-flats dimension and follow the assembly drawing or OEM torque specification for the application. Inspect threads on the mating fastener for damage or contamination before installation.
