A specialized tool designed for removing damaged or rounded fasteners, this implement typically features a spiraled or fluted internal socket that grips the fastener head when turned counterclockwise with a compatible ratchet or breaker bar. The half-inch drive size refers to the square recess on the back of the socket, which dictates the size of the drive tools it can be used with. A common example is its use for extracting stripped hex-head bolts.
This type of extraction tool offers significant advantages in various mechanical and automotive applications. Its ability to remove otherwise irretrievable fasteners prevents damage to surrounding components and materials, often saving time and costly repairs. The development of such tools represents a significant advancement in mechanical repair, offering a less destructive alternative to traditional methods like drilling or welding. The standardized half-inch drive ensures compatibility with a wide range of commonly available drive tools.
