Split Beam Nut
A split beam nut, also known as a split hex nut. or slotted beam nut, is a locknut with slots cut in the top that separate the outside end into two. or more sections that are bent slightly inward, making the thread diameter undersized in the slotted portion. As the nut is threaded on, these sections are forced back out to their original position and increase the friction between the nut and the fastener, creating the locking action. High temperature use High strength grades retain their locking ability up to , unlike nyloc nuts. Military grade nuts can be reused at least a dozen times.Smith, p. 105 Trademark Aerotight is a tradename for a specific type of split beam nut. Other names for this type of nut are stiff nut and Allmetal self locking nut.

Locknut
A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut,. stiff nut or elastic stop nut, 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. Free-spinning locknuts exist which carry the advantage of not requiring extra torque until seated. Types There are various kinds of specialised lock nuts, including: * Castellated nut * Distorted thread locknut ** Centerlock nut **Elliptical offset locknut ** Toplock nut **Philidas nut * Interfering thread nut ** Tapered thread nut * Jam nut * Jet nut (K-nut). * Keps nut (K-nut or washer nut) with a free-spinning washer. In the locknut form, this is a star-type lock washer. * Plate nut * Polymer insert nut (Nyloc nut) * Security locknut All steel reusable nut for high vibration and harsh environments. * Serrated face nut * Serrated flange nut * Speed nut (sheet metal nut or Tinnerman nu ...

Nut (hardware)
A nut is a type of fastener with a screw thread, threaded hole. Nuts are almost always used in conjunction with a mating bolt (fastener), bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction (with slight deformation (engineering)#Elastic deformation, elastic deformation), a slight Tension (physics), stretching of the bolt, and compression (physics), compression of the parts to be held together. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, eccentric double nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins (split pins) or lockwire in conjunction with castellated nuts, nylon inserts (nyloc nut), or slightly oval-shaped threads. Square nuts, as well as bolt heads, were the first shape made and used to be the most common largely because they were much easier to manufacture, especially by hand. While rare to ...

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. The screw thread does not cut into the nylon insert, however, the insert deforms elastically over the threads as tightening pressure is applied. The insert locks the nut against the screw as a result of friction, caused by the radial compressive force resulting from the deformation of the nylon. Nyloc nuts retain their locking ability up to . Trademark There are no registered trademarks filed in the United States for "Nyloc" or "Nylock" that are currently active in regards to fasteners. In Australia, "nyloc" is a registered trademark. Related fasteners A nylon pellet nut is very similar to a nyloc nut except that it uses one or more smaller nylon inserts i ...

Elliptical Offset Locknut
A distorted thread locknut,McMaster, p3139 is a type of locknut that uses a deformed section of thread to keep the nut from loosening from vibrations or rotation of the clamped item. They are broken down into four types: elliptical offset nuts, centerlock nuts, toplock nuts and partially depitched (Philidas) nuts. High temperature use Because these nuts are solid metal, they are effective in elevated temperature settings, unlike nyloc nuts. High grade nuts can withstand temperatures up to . Safety factors High strength distorted thread nuts cannot be used with low strength fasteners because the hard nut will act like a die and destroy the threads on the fastener. Elliptical offset nuts Elliptical offset nuts is a catch-all category that encompasses designs known as oval locknuts or non-slotted hex locknuts,. The salient feature is that the thread form has been deformed at one end so that the threads are no longer perfectly circular. The deformed end is usually shaped into an ellip ...
