What is the definition of a flex head ratchet wrench?

A flex head ratchet wrench is a type of hand tool that features a flexible head, allowing the user to adjust the angle of the ratcheting mechanism. This design provides increased accessibility and maneuverability in tight spaces where a standard fixed head ratchet would be difficult to use. The tool typically includes a ratcheting mechanism that allows for easy tightening or loosening of fasteners without the need to reposition the wrench after each turn. Flex head ratchet wrenches are commonly used in automotive and mechanical applications.
