Staples

An office stapler binds together a stack of paper

A staple is a metal fastener, distinct from a bolt, or rivet, used to make a connection. Crimping, or other mechanical deformation, is often used to make the connection.

In ordinary life the most common staple encountered is a wire or rod inserted into multiple sheets of paper, and then deformed, to fasten them together.

Surgical staples are sometimes used, instead of stitches.

Large U-shaped metal staples are pounded into wood, in order to secure them to chains or cables.
