  • Patent number: 9027445
    Abstract: A socket includes a body and a sleeve. The body is made of metal and includes first and second coupling ends for respectively coupling with a fastener and a driving tool. The first coupling end includes an outer periphery having a first protruded section, a second protruded section, and an engagement section extending between the first and second protruded sections. The sleeve is made of metal having a hardness greater than a hardness of the body. The sleeve includes an inner periphery extending between first and second end faces of the sleeve. The inner periphery of the sleeve includes an engagement portion engaged with the engagement section of the body, with the sleeve not contacting the first and second protruded sections.

  • Patent number: 8950297
    Abstract: A socket includes a body and a reinforcing sleeve. The body includes first and second coupling ends for respectively coupling with a fastener and a driving tool. The first coupling end includes a conical section having a small diameter end and a large diameter end. A spacing between the small diameter end and the second coupling end along the longitudinal axis is smaller than a spacing between the large diameter end and the second coupling end along the longitudinal axis. The conical section has increasing diameters perpendicular to the longitudinal axis away from the second coupling end. The reinforcing sleeve is mounted around the conical section of the body to reinforce the socket.
