WitrynaBoth types of locknuts have the locking feature implied in their names, yet this feature is accomplished very differently between the two nuts. Prevailing Torque Locknuts. Prevailing torque locknuts require a considerable amount of torque to both tighten and loosen the nut, regardless of a lack of tension in the mating bolt or stud. Witryna17 kwi 2012 · What manufacturers sometimes do is 'calibrate' the torque value vs preload for a given clamping scenario. In this case, it depends if the manufacturer has already taken the prevailing torque (torque required to get the nylock nut moving) into account when specifying the torque to apply. If it's unknown I'd just add it, it's only a …
