ABSTRACT:
A chuck for use in screwing one threaded member into another threaded member has a housing with a polygonal socket on one end for receiving a polygonal drive head of a wrench. The housing has a conical bore converging from the face toward the socket. A plurality of retainers are releasably mounted in the bore in a circular array. Each retainer has edges on opposite sides that are spaced apart from the edges of the adjacent retainers to define a receptacle between each of the retainers. A plurality of blades are releasably inserted into the receptacles. Each blade has a gripping edge that protrudes inward from the receptacle, defining with the gripping edges of the other blades a conical space that converges toward the socket for gripping one of the threaded members.
