Prevailing torque nuts The locking action, created by distortion of their top threads, is said to resist loosening caused by shock, vibration and other dynamic forces. Break-loose Torque: is the torque applied in a removal Prevailing Torque in Locking Nuts For nuts, particularly locking nuts, prevailing torque refers to the force required to securely tighten the nut onto a threaded fastener. Prevailing torque lock nuts are one piece, prevailing torque hex nuts with a conical top and a flat bottom bearing surface with chamfered corners. Locking nuts often incorporate features such as nylon inserts or deformed threads to increase friction, making them highly resistant to loosening under vibrations or external Nov 23, 2024 · Prevailing torque lock nuts utilize a specialized mechanism to maintain a secure fit even under conditions that typically cause loosening, such as vibration and dynamic forces. Resistance to loosening: Reliable against vibration-induced loosening. Choose from our selection of prevailing torque locknuts, including nylon-insert locknuts, distorted-thread locknuts, and more. During the first time dis-assembly of matting threads it is called as 1st OFF torque, during second time dis-assembly it is called as 2nd OFF torque and so on. Apr 30, 2025 · Prevailing torque lock nuts are widely used in industries such as automotive, aerospace, construction, and manufacturing due to their exceptional vibration resistance and secure fastening capabilities. This mechanism involves creating resistance to rotation through an interference fit between the nut and the mating part, such as a bolt. . Ease of installation: Can be installed with standard tools. Prevailing OFF torque: is the torque measured (maxi-mum value) when the fastener is being removed away from its seating position. Same and Next Day Delivery.
