a driving direction control assembly comprising a cylindrical roller, a spring assembly and a driving direction control switch, said control switch being mounted for movement with respect to said tool body and said fastener engaging mechanism between first and second operative switch positions, said control switch, said spring assembly and said cylindrical roller being constructed and arranged such that
(1) when said control switch is in its first operative switch position and said fastener engaging mechanism is releasably coupled to a fastener, said cylindrical roller is positioned such that (a) rotating said tool body about the rotational axis in a first rotational direction forces said cylindrical roller essentially instantaneously into a first wedged relation between surfaces on said tool body and said fastener engaging mechanism, thereby preventing relative rotational movement between said fastener engaging mechanism and said tool body so that rotational movement of said tool body in the first rotational direction rotates the fastener in the first rotational direction and (b) rotating said tool body about the rotational axis in a second rotational direction opposite the first rotational direction moves the cylindrical roller against the biasing of the spring assembly out of the first wedged relation, thereby allowing said tool body to rotate relative to said fastener engaging mechanism, and
(2) when said control switch is in its second operative switch position and said fastener engaging mechanism is releasably coupled to a fastener, said cylindrical roller is positioned such that (a) rotating said tool body about the rotational axis in the second rotational direction forces said cylindrical roller essentially instantaneously into a second wedged relation between surfaces on said tool body and said fastener engaging mechanism, thereby preventing relative rotational movement between said fastener engaging mechanism and said tool body so that rotational movement of said tool body in the second rotational direction rotates the fastener in the second rotational direction and (b) rotating said tool body about the rotational axis in the first rotational direction moves the cylindrical roller against biasing of the spring assembly out of the second wedged relation, thereby allowing said tool body to rotate relative to said fastener engaging mechanism.
2. A hand tool according to claim 1, said spring assembly comprising a pair of coil springs each being mounted to said control switch on opposing sides of the cylindrical roller.
3. A hand tool according to claim 2, wherein said control switch is located on said tool body between said opening therein and said grippable portion thereof.

A hand tool according to claim 1, wherein said opening extends through said tool body, said tool body including an annular lip surrounding one end of said opening and extending into said opening, said hand tool further comprising a cover removablely mounted on said tool body, said cover covering an opposite end of said opening, said fastener engaging mechanism being removablely mounted in said opening between said annular lip and said cover, said fastener engaging mechanism being removable from said tool body when said cover is removed from said tool body.
8. A hand tool according to claim 7, wherein said fastener engaging mechanism includes a elongated structure extending axially outwardly from one side of said opening in said tool body along the rotational axis of said opening, said elongated structure being configured to be coupled to a socket which can be removablely coupled to a fastener.
9. A hand tool according to claim 1, wherein said control switch is releasably lockable in the first and second operative switch positions thereof.
10. A hand tool according to claim 9, further comprising a detent mechanism operable to releasably lock said control switch in the first and second operative switch positions thereof.
