Gibraltar 41709G Flange Nut 1-14 Thread 12L14 Steel

Product Description

The GIBRALTAR 41709G is a heavy-duty flange nut designed for high-load fastening applications in mechanical, industrial, and trade assembly work. Manufactured from 12L14 steel with a black oxide finish, this nut provides corrosion resistance and consistent clamping performance. It features a 1-14 thread size, a 2-inch flange diameter, and stands 1.25 inches high. The integrated flange distributes load across the bearing surface, reducing the need for a separate washer and improving joint integrity. Licensed trades and industrial assemblers working on structural or mechanical connections will find this nut meets TCMAI fastener standards.

This flange nut is suited for bolted assemblies requiring a wider bearing surface and reliable thread engagement. The 1-14 thread pitch makes it appropriate for applications where fine-thread engagement is specified, such as in mechanical equipment, industrial machinery, and precision structural connections. The black oxide finish is compatible with both indoor and controlled-environment outdoor applications where moderate corrosion resistance is acceptable.

Compatibility

Designed as an OEM-style replacement or maintenance fastener for bolted assemblies requiring a 1-14 thread flange nut in inch-measurement systems.

Installation Notes

Installation should be performed by qualified mechanical or trade personnel familiar with fastener torque specifications for the specific application. Always verify thread engagement and flange seating before final tightening. Do not mix inch and metric fastener standards in the same joint assembly. Inspect mating bolt threads for damage or contamination before installation.
