F-Crimp is a type of solderless electrical crimp connection.
F-Crimp is a more mechanically robust crimp connection compared to the common barrel-crimp type readily available at retail locations (Radio Shack, Home Depot, etc.).
The term F-Crimp was originally coined by AMP Incorporated (now TE Connectivity), however terminals of this style are currently manufactured by multiple companies.
Crimpers are available from multiple sources: manufacturers of the connectors typically offer industrial crimp devices for high volume production, and specialized hand tools companies such as Ideal, Eclipse and Greenlee (formerly Paladin) offer dies for hand crimpers.
Non-AMP crimpers are available in "ratcheting" ("Certi-Crimp") and non-ratcheting versions, but only ratcheting types are suitable for production applications, with non-ratcheting types being suitable for occasional, or "field" repairs.
