Nyloc Nut: A self-locking nut featuring a nylon insert. The nylon collar in the top portion of the nut locks it in place by squeezing the threads of a bolt or screw as the nut is tightened, creating friction which prevents loosening. Re-usable to an extent but efficiency decreases with every use, over-time will become ineffective.
Can be used at temperature extremes of between -40C to 120C.

Some Wing Nuts have rounded wings (often referred to as "European/German" type) and others feature flatter/squared off wings (often referred to as American type) this is primarily due to differences in manufacturing processes.

Metal Self Locking Nuts: Sometimes referred to as a bent beam nut or All-Metal Locking Nut, these nuts create friction between the threads, which causes a distortion of the threads locking it in place. Used in environments where vibration may be a problem. They will lose their locking ability after a few uses. Common brands are Aerotight, Cleveloc, Philidas, Philidas Turret, Stover and Binx nuts.

Square Roofing Nuts: Square nuts used with roofing bolts.
Cage Nuts: Also known as captive nuts. Square nuts held inside a spring steel cage. The cage features two wings which are compressed allowing installation into a hole. When installed the wings release and the outward pressure of the spring holds the cage nut in position.
Castle Nuts: Slotted Hexagon nuts with turrets on the top, which resemble a castle wall, they are used with bolts that have a hole through the end which a pin (such as a cotter or spring pin) can pass through to lock into position and prevent rotation.
Slotted Nuts: alike to Castle nuts, also feature a turret top, however the castellated section diameter is the same as the main wrenching section (which is slightly smaller in a castle nut).
