NT Retaining Nut

NAN.GIF

Designed by WHITTET-HIGGINS to provide the necessary holding power in a more limited space, these thin section locknuts are generally 50% to 75% the thickness of the N-AN series of locknuts. To provide greater clearance, they have a smaller outer diameter (O.D.). These smaller dimension locknuts weigh less. These thin section locknuts have become increasingly popular in the aircraft, computer, electronics and machine tool industries using small bearings, classified generally as Extremely Light and Extra Light, where the usual locknut would be as large or larger than the bearing. They are used with the WT series of lockwashers.
