Abstract:
1. A socket comprising: a body made of metal, with the body including a first coupling end and a second coupling end opposite to the first coupling end, with the first coupling end including an actuating hole extending along a longitudinal axis of the body, with the actuating hole including non-circular cross sections, with the actuating hole adapted to couple with a fastener, with the second coupling end including a driving hole extending along the longitudinal axis of the body, with the driving hole having non-circular cross sections, with the driving hole adapted to couple with a driving tool, with the first coupling end including an outer periphery having a first protruded section, a second protruded section, and an engagement section extending between the first and second protruded sections; and a sleeve made of metal having a hardness greater than a hardness of the body, with the sleeve including first and second end faces and an inner periphery extending between the first and second end faces of the sleeve, with the inner periphery of the sleeve including an engagement portion engaged with the engagement section of the body, with the engagement portion of the sleeve having an initial inner diameter before the sleeve is mounted on the body, with the initial inner diameter slightly smaller than an outer diameter of the engagement section perpendicular to the longitudinal axis of the body, with the engaging portion of the sleeve not contacting the first and second protruded sections of the body, with the sleeve including a first thickness between the engagement portion and an outer periphery of the sleeve, with the first coupling end of the body having a second thickness between the engagement section and an inner periphery of the first coupling end, with the first thickness larger than the second thickness, with the engagement portion of the sleeve mounted around the engagement section of the body by tight coupling, avoiding the sleeve from disengaging from the body.
