Nuts are almost always used in conjunction with a mating bolt to fasten two or more parts together. The two partners are kept together by a combination of their threads' friction, a slight stretching of the bolt, and compression of the parts to be held together. 

In situations where the risk of nut loosening due to vibration or rotation is a concern, various locking mechanisms can be employed, including lock washers, jam nuts, specialized adhesive thread-locking compounds like Loctite, safety pins (split pins), or lockwire used in combination with castellated nuts, nylon inserts (Nyloc nuts), or slightly oval-shaped threads.

The hexagonal shape is the most common choice for nuts, much like bolt heads, due to practical reasons. Its six sides provide a balanced distribution of angles for efficient tool access, especially in tight spaces. The hexagonal shape requires only a 1/6th rotation to access the next side, ensuring optimal grip. Other polygonal shapes with more or fewer sides may not offer the same level of grip. Additionally, specialized nut shapes, such as wingnuts for finger adjustment and captive nuts like cage nuts for hard-to-reach areas, are designed to meet specific requirements.

Nuts come in a wide variety, ranging from household hardware versions to industry-specific designs engineered to meet various technical standards. Fasteners used in the automotive, engineering, and industrial sectors often require precise torque settings achieved using a torque wrench. Nuts are graded based on strength ratings that match the corresponding bolts. For example, an ISO property class 10 nut is capable of supporting the proof strength load of an ISO property class 10.9 bolt without stripping, while an SAE class 5 nut can withstand the proof load of an SAE class 5 bolt, and so on.
