Locking torque vs prevailing torque

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 …

WitrynaThe prevailing torque will vary less than 75% from the value shown from the first to the fifth installation and beyond. 3) Calculated using formula: Nominal diameter x Clamp Load (from note 1) x Friction factor (dimensionless value of 0.20 for dry installation). What is prevailing torque lock nut? WitrynaFriction originates at two contact interfaces; between the turned part and the clamped part (often under the bolt head or under the nut) and in the threads. This means that the portion of torque that transforms into …

Witrynathe prevailing torque. The higher the prevailing torque the higher is the resistance to self-loosening. The disadvantage of too high a prevailing torque is that torsional stresses are induced into the thread which results in premature yielding that limits the preload that can be achieved. 2.
