Jergens 19907 Flange Nut 5/8-11 Unc Black Oxide Steel

Product Description

The JERGENS 19907 is a flange nut designed for standard UNC threaded fastener applications. It features a 5/8-11 thread size with a Class 2B thread fit, providing reliable engagement in typical mechanical and structural assemblies. The integrated flange distributes clamping load over a wider bearing surface, reducing the need for a separate washer in many installations. Constructed from low carbon steel with a black oxide finish, this nut offers moderate corrosion resistance suitable for indoor and protected environments. The nut weighs 0.175 pounds and meets TCMA fastener standards.

This flange nut is suited for general industrial, mechanical, and structural fastening tasks where a 5/8-11 UNC threaded connection is required. Common installation scenarios include equipment assembly, mounting fixtures, and maintenance applications across manufacturing, mechanical contracting, and facility maintenance trades. The black oxide finish makes it appropriate for interior use or applications where light corrosion protection is acceptable.

• Low carbon steel construction provides solid mechanical strength
• Black oxide finish for light corrosion resistance in protected environments
• Meets TCMA fastener standards
• Compact profile: 13/16 inch height with 1-1/16 inch width across flats

Compatibility

Designed as a standard replacement or new-installation flange nut for 5/8-11 UNC threaded fastener assemblies in industrial and mechanical applications.

Installation Notes

Installation is performed using a standard wrench sized for 1-1/16 inch across flats. Ensure mating threads are clean and free of debris before assembly. Follow applicable torque specifications from the equipment manufacturer or relevant fastener standards for the application. Always de-energize or shut down equipment before performing fastener service on live mechanical systems.
