For more than 50 years, Greer Stop Nut has been recognized as a major supplier of internally threaded fasteners. Greer Locknuts offer quality and reliability for common applications in the transportation, communications, electronics, defense, and other industries.

Operating out of a 90,000 square foot facility in Nashville, Tennessee, the GREER STOP NUT® Locknut product portfolio consists of nylon insert hex, clinch, and spline nuts, plus a variety of all-metal nuts in standard and made-to-order configurations.

GREER STOP NUT® Locknuts meet MS, MIL, AN and NAS specifications and are available in a variety of finishes, platings and materials. The nylon insert material resists most organic acids, oils, greases and common solvents and mineral acids.

The toughness and resiliency of the nylon insert withstand the highly abrasive action caused by nicked threads in mating fasteners, thereby increasing reliability and reducing downtime from failed installations.
