The rim or edge of a crater is the part that extends above the height of the local surface, usually in a circular or elliptical pattern. In a more specific sense, the rim may refer to the circular or elliptical edge that represents the uppermost tip of this raised portion. If there is no raised portion, the rim simply refers to the inside edge of the curve where the flat surface meets the curve of the crater bottom.

A rim is an external flange that is machined, cast, molded, stamped or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called "flanged" cartridges. Almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as "rimless cartridges". The rim may serve a number of purposes, including providing a lip for the extractor to engage, and sometimes serving to headspace the cartridge

The rim of a coin is the up-raised part of the coin that completely encircles the diameter on both obverse and reverse sides. Not to be confused with the edge of the coin, which is also known as its "third side".

This is the part which exceeds the area of the die which strikes the coin during production, and as a result is pushed upward and sharpened to form a sort of border around the coin's design. The raised rim reduces wear on the face of the coin.

For accessibility purposes, the rim of the coin is sometimes milled with certain patterns in order for the blind to more easily distinguish between coins. In Australia, the two dollar coin has periodically distributed around its edge a short set of grooves, which alternate between the smooth rim, whilst the one dollar coin has a larger set of grooves, and the similar sized ten cent coin has grooves continuously about its edge.

The rim is the "outer edge of a wheel, holding the tire". It makes up the outer circular design of the wheel on which the inside edge of the tire is mounted on vehicles such as automobiles. For example, on a bicycle wheel the rim is a large hoop attached to the outer ends of the spokes of the wheel that holds the tire and tube. The term rim is also used non-technically to refer to the entire wheel, or even to a tire.

In the 1st millennium BC an iron rim was introduced around the wooden wheels of chariots.
