What is a Lock Nut?
A lock nut also known as a locking nut, self-locking nut, prevailing torque nut, stiff nut or elastic stop nut. Lock nut is a nut that resists loosening under vibrations and torque. Elastic stop nuts and prevailing torque nuts are of the particular type where some portion of the nut deforms elastically to provide a locking action. This makes them useful for holding wheels onto axles, or in automotive engines where machine vibration would otherwise loosen the fastener. Lock nuts may also be used as jam nuts, threaded over another nut to keep it in place. Locking nuts should be used when the screw joint consists of one or more soft materials. It is difficult to achieve and to maintain a high level of clamp load because the soft material deforms due to high surface pressure. This plastic deformation continues after the torque value has been applied to the screw.
Inspection & Testing of Lock Nut
- Mechanical Testing Such as Tensile of Area, Hardness Test, Positive Material Identification – PMI Testing, Flattening Test, Micro and Macro Test, Pitting Resistance Test, Flaring Test, Intergranular Corrosion (IGC) Test.
