Abstract:
A socket for a wrench comprising:a body having an axial length, a first end and a second end along the axial length, with the body having a central hole extending from the first end, with the central hole having an inner surface defined in the first end of the body; a connecting device formed on the second end of the body to be adapted to connect to the wrench; multiple first protrusions formed on the inner surface of the central hole, with the multiple first protrusions spaced circumferentially and extending longitudinal the body, with each first protrusion of the multiple first protrusions having a peak with a first angle, with each first protrusion having a first side and a second side, with the peak defined by the interconnection of the first side and the second side, with the first side of each first protrusion being planar; multiple second protrusions is formed on the inner surface of the central hole, with each second protrusion of the multiple second protrusions located between each pair of adjacent first protrusions, with each second protrusion having a peak with a second angle, a first side, a second side and a recess defined in the first side, with the peak of each second protrusion defined by the interconnection of the second side to the recess, with the recess having a radius to make the second angle of each peak of the second protrusion smaller than the first angle of the peak on each first protrusion, with the recess defining an auxiliary peak on the first side, with the recess being intermediate the peak and the auxiliary peak of each second protrusion; and a gap defined between each respective second protrusion and each respective first protrusion of each pair of adjacent first protrusions that is adjacent to the each second protrusion, with the auxiliary peak being intermediate the recess and an interconnection of the first side with the gap.
