What is a Lock Nuts?

A lock nut also known as a locking nut, self-locking nut, prevailing torque nut, stiff nut or elastic stop 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. The first type used fiber instead of nylon and was invented. Lock nuts are very useful and are used by engineers and mechanics. As the nut is tightened, the thread on the sheaf axle cuts into the nylon holding i A nylon nut also referred to as a nylon-insert lock nut, polymer-insert lock nut or elastic stop nut, is a kind of lock nut with a nylon collar insert that resists turning. The plastic insert is placed at the end of the nut, with an inner diameter  slightly smaller than the major diameter of the screw.t firmly in position. As the wheel rotates a normal nut will loosen because of friction and vibration of the wheel.

Types of Lock Nuts

RADIAL LOCKNUTS (Available Models MR/MRZ/SR)

  • There are specialized lock screws which intersect at a right angle with the axis. This is specifically designated for a restricted space.
  • The sizes for the internal treads range from M6 X 0.5P to M200X 3.0P.
  • The MR Model with the thread is designed to face a squaring of 0.002 mm by the process of grinding.
  • The MRZ or the MR Model is designed to face squaring of 0.005mm by turning the thread.
  • The SR Model comes with a lesser thickness as well as a lesser outer diameter as compared to the MR series. However, it is at par with the ZM model.

AXIAL TYPE LOCKNUTS (Available Model MKR)

  • This particular series is specifically designed to generate the capacity of a powerful braking. Thus happens due to the deformation of entire locknut itself. This makes both the male & the female threads contact each other very tightly.
  • The available sizes range from MKR 10 X 0.75 P to MKR 200 X 3.0P ( 58 sizes).
  • The thread to the face squaring is 0.005 mm.

ANGLE LOCKNUTS (MF/TMF/FZ)

  • The specifically designed lock screws intersect at an angle of 30 Degrees with the axis accompanying along with a specific threading design. This builds a perfect attachment between the braking copper and the threading surface and results in securing a very high stability and precision.
  • The MF Model is available in a size range from M12 X 1.0 P to M200 X 3.0 P by grinding the sizes i.e. the internal treads. This model has a thread to face squaring of 0.0002mm.
  • The TMF Model is available in a size range from M25 X 1.5 P to M200 X 3.0 P by grinding the sizes i.e. the internal treads. This model has a thread to face squaring of 0.0002mm
  • The MF Model is also available in a size range from M12 X 1.0 P to M200 X 3.0 P by turning the sizes i.e. the internal treads. This model has a thread to face squaring of 0.0005mm.
  • The SMF Model is available in a size range (internal threads) from M10 X 0.75 P to M110 X 2.0. This model has a thread to face squaring of 0.0005mm.
