Nyloc nut. A nyloc nut, also referred to as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut, is a kind of locknut with a nylon collar that increases friction on the screw thread. The nylon collar insert is placed at the end of the nut, with an inner diameter (ID) slightly smaller than the major diameter of the screw.
A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, [1] stiff nut [1] or elastic stop nut, [2] is a nut that resists loosening under vibrations and torque. Prevailing torque nuts have some portion of the nut that deforms elastically to provide a locking action. [ 2 ]

In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, eccentric double nuts, [1] specialist adhesive thread-locking fluid such as Loctite, safety pins or lockwire in conjunction with castellated nuts, nylon inserts , or slightly oval-shaped threads.

A positive locking device is a device used in conjunction with a fastener in order to positively lock the fastener. This means that the fastener cannot work loose from vibrations. The following is a list of positive locking devices: [1] A split beam nut; A castellated nut and a split pin; A hex nut or cap screw and a tab washer
An interfering thread nut is a type of locknut that has an undersized root diameter. This creates an interference between the nut and the fastener, plastically deforming the threads on the fastener. Due to this deformation they are usually only used on permanent or semi-permanent installations. [1] A variation of this nut is the tapered thread nut.
A distorted thread locknut, [1] is a type of locknut that uses a deformed section of thread to keep the nut from loosening due to vibrations, or rotation of the clamped item. . There are four types: elliptical offset nuts, centerlock nuts, toplock nuts and partially depitched (Philidas) nu
