Ratschenschlüsseln

Ratschenschlüsseln, also known as ratcheting wrenches or socket wrenches, are hand tools used for tightening or loosening fasteners. Their primary distinguishing feature is a ratcheting mechanism built into the handle. This mechanism allows the user to turn the fastener continuously without having to remove and reposition the wrench after each partial turn.

The ratcheting mechanism typically consists of a gear and a pawl. As the handle is moved in one direction, the pawl engages with the gear teeth, turning the socket. When the handle is moved in the opposite direction, the pawl slips over the teeth, allowing for a back-and-forth motion without turning the fastener. This makes them significantly more efficient than standard wrenches, especially in confined spaces where full rotations are difficult.

Ratschenschlüsseln usually come with a set of interchangeable sockets of various sizes to fit different fasteners. The sockets attach to a drive head on the wrench. Some models also feature a reversing lever, allowing the user to easily switch between tightening and loosening modes without having to flip the wrench. They are commonly used in automotive repair, construction, and general mechanical work due to their speed and convenience.
