Typically, the metals are joined together via a special connector. Stripped wire (often stranded) is inserted through the correctly sized opening of the connector, and a crimper is used to tightly squeeze the opening against the wire. Depending on the type of connector used, it may be attached to a metal plate by a separate screw or bolt or it could be simply screwed on using the connector itself to make the attachment like an F connector.
Obtaining a good crimp requires using carefully engineered crimp tools and crimp connectors, and following the procedures specified by the manufactures. Examples of these procedures can be obtained from Molex, TE Connectivity, RS Pro, and other similar companies.
Crimping is most extensively used in metalworking. Crimping is commonly used to fix bullets in their cartridge cases, for rapid but lasting electrical connections, securing lids on metal food cans, and many other applications. Because it can be a cold-working technique, crimping can also be used to form a strong bond between the workpiece and a non-metallic component.

According to one of the crimp tool manufacturers, the development of standardized crimp tools and procedures occurred on this timeline.
- 1940's All terminations were soldered (Hard-wired)
- 1953 AMP introduced Crimp Barrel Terminals
- 1957 Cannon Brothers experimented with Machined Contacts with Crimp Barrels
- 1960 Buchanan introduced the MS3191-1 4 Indent Crimp Tool with a Ratchet
- 1963 MS3191-1 was published as the first Crimp Tool Standard
- 1965 MS3191-4 introduced by Daniels Manufacturing Corporation
- 1969 MIL-T-22520 published and dated to replace all previous specifications
- 1974 Changed to MIL-C-22520, and many Slash Sheets added
- 1996 Changed to MIL-DTL-22520
- 2010 Changed to AS22520
