An universal socket wrench, which includes a socket body for attaching to the workpiece to be turned, a locating block mounted in the socket body, the locating block having a plurality of through holes through top side and bottom sides thereof, a solid cover plate covered on the bottom side of the locating block, a pad covered on the top side of the locating block, the pad having a plurality of insertion holes respectively axially aligned with the through holes at the locating block, a plurality of spring members respectively mounted in the through holes inside the locating block, a plurality of rod members respectively inserted through the through holes at the pad into the through holes at the locating block and supported on the spring members, the rod members each having an outer end terminating in a holding down block suspended outside the locating block, and a plurality of connecting members stopped inside the locating block by the pad and respectively connected between the spring members and the rod members. The rod members are stopped at the top side and around the peripheral wall of the workpice when the socket body is attached to the workpiece, enabling the workpiece to be positive turned with the socket body by a handle being coupled to the socket body.

A socket includes a housing and a plate secured in the housing and having a number of apertures for slidably receiving a number of rods. A number of posts are secured to the rods and each includes a hexagonal cross section having six surfaces for engaging with the fasteners. A number of springs are engaged with the posts for allowing the posts to be depressed inward of the housing and for allowing the socket to engage with the fasteners of various sizes. The surfaces of the posts may solidly engage with the fastener for solidly retaining the fasteners in place.

A tool comprising a drive shaft with a longitudinal axis and a socket attached to the drive shaft. The socket includes a cavity having a substantially rectangular opening defined by a pair of parallel side walls of the first side length and a U-shaped wall having two parallel walls adjacent to the opening and a curved portion of the U-shaped wall opposite the opening. In this manner, the cavity is shaped to fit the contour of a typical screw hook such that the screw hook can be anchored to a wall or ceiling with relative ease because the screw hook will not rotate away from the longitudinal axis of the tool.

An adapter for adapting use of a universal socket tool or wrench to a tool bit is disclosed. The universal socket contains a plurality of spring biased pins closely packed in parallel to apply torque to bolts, nuts, and similar fasteners. To broaden the utility of such a universal socket, the adapter holds a hex shanked screwdriver bit into the socket so that the pins can apply torque to the screwdriver shank. The adapter further stabilizes the bit drive end so that the bit does not wobble. The adapter has a body with a hole at one end to receive a bit and a recess at the opposite end to receive the socket. The adapter is made of an elastomeric material so that the bit can easily be forced into the hole and the socket can be forced into the recess. The recess has a minimum inside width or diameter at its open end so that a lip of the recess contacts the socket exterior away from the socket end.

A universal socket wrench includes a housing having an inner bore and an outer opening of different sizes for forming a shoulder between the opening and the bore. The housing has a number of depressions communicating with the shoulder of the housing. A plate is engaged with the opening and the shoulder of the housing and has a number of projections engaged with the depressions of the housing for solidly securing the plate to the housing. A number of spring biased posts are slidably engaged with the plate for driving fasteners of various sizes.
