Abstract: A socket is portably and removably attached to a tool and includes a body with a mounting hole which includes multiple faces. Each face includes a first protrusion and two groups of second protrusions located on two sides of the first protrusion. The first protrusion of each face includes a first flat distal surface which has a certain length. Each second protrusion includes a second flat distal surface which is tilt relative to the first flat distal surface. The two respective slopes of the second flat distal surfaces of the two groups of the second protrusions are opposite to each other. A first imaginary plane is co-linear with the first flat distal surface. A second imaginary plane is co-linear with the second flat distal surfaces of each second protrusion. An angle is formed between the first and second imaginary planes. The socket can drive a normal or rounded bolt.

Abstract: A finger ratchet tool includes a body having a top part on the top thereof, and a ratchet device connected to the underside of the body. The top part includes a tapered face in the outer periphery thereof. Two flanges extend radially from the top part. A connection portion extends from the body. A mounting member has a C-shaped collar which has an opening, and a rod is connected between two ends of the opening. A matching face is defined in the inner periphery of the C-shaped collar. Two recesses are defined in the C-shaped collar and each have two ends. The rod is pivotably connected to the connection portion, and the C-shaped collar is mounted to the top part to match the matching face with the tapered face. The flanges are engaged with the recesses.

Abstract: A socket includes a body with a mounting hole which includes multiple faces. Each face includes a first protrusion and two groups of second protrusions which are located on two sides of the first protrusion. A first imaginary plane extends in parallel from the distal surface of each first protrusion. Two second imaginary planes respectively extend laterally from the center of the distal surface of each first protrusion. An angle is defined between the first imaginary plane and each of the second imaginary planes. Each of the second imaginary planes pass respective distal surfaces of the second protrusions of each group in parallel. A notch is defined between adjacent second protrusions. A groove is defined between adjacent faces of the mounting hole.

Abstract: Manufacturing steps for manufacturing a hand tool include a step of preparing a base part which has a handle end and a head end; a step of molding: placing the base part in a molding device and coating plastic to the whole base part by way of plastic injection molding to form the base part into a semi-product which has a handle portion and a head portion, an installation hole defined through the head portion; a step of coating: electro-coating a material to outer surface of the plastic of the semi-product, and a step of assembly: assembling a ratchet driving unit in the installation hole by using fixing members so as to obtain a final product.
