LOCKNUTS Meaning and
Definition
-
Locknuts, also referred to as locking nuts or prevailing torque nuts, are threaded fasteners commonly used in various mechanical applications where vibration or loosening may occur. They are designed with a special feature that adds resistance to unscrewing, providing enhanced safety and reliability.
These nuts possess a locking mechanism that prevents unintended loosening due to external forces or vibrational forces that occur during the operation of machinery or vehicles. This mechanism is achieved through various engineering designs, including nylon inserts, deformed threads, or a metal ring.
The nylon insert locknuts, also known as nylon lock nuts or nyloc nuts, are equipped with a nylon ring embedded within the nut's top portion. As the nut is threaded onto a bolt or screw, the nylon ring compresses against the threads, creating a strong frictional force. This frictional force resists vibrations and prevents the locknut from rotating freely, thereby preventing loosening.
Deformed thread locknuts, on the other hand, feature distorted threads that create extra resistance against loosening. The deformation provides a prevailing torque or prevailing resistance, ensuring the nut remains securely fastened even under high levels of vibration.
Metal ring locknuts, often referred to as high-strength locknuts or all-metal locknuts, incorporate a hardened metal ring that acts as a locking device. This metal ring is typically serrated or indented, creating a mechanical interference fit between the threads of the nut and the bolt or screw. This interference fit generates high resistance to rotation, making it difficult for the nut to loosen unintentionally.
Overall, locknuts offer an effective means of securing fasteners in applications prone to vibration, ensuring the integrity and safety of the assembly.

Etymology of LOCKNUTS
The word "locknut" is a combination of two separate words: "lock" and "nut".
The term "lock" originated from the Old English word "loc", which referred to something fastened or closed securely. As for "nut", it comes from the Old English word "hnutu", meaning "hard-shelled fruit" or "nut". Over time, this term began to be used specifically for the small, usually metal, object used to fasten or tighten bolts or screws.
In the case of "locknut", it refers to a type of nut specifically designed to prevent loosening or unwanted movement of fasteners. These nuts feature special mechanisms or designs that provide extra security to prevent vibrations or other external forces from causing the nut to come loose.
So, the word "locknut" simply combines the concept of a fastener (nut) with the notion of secure fastening (lock).
