1. A retention socket for torquing and retaining a fastener, the socket comprising:
- a body having a plurality of interior faces disposed about a receptacle for receiving a fastener having a plurality of sides, said body having an open end and a closed end and said receptacle having an axis of rotation,at least one interior face having at least two retention ridges separated by a surface forming a concave depression so that at least one of the sides of the fastener, when received in the receptacle, is engageable by both retention ridges and not by the surface,wherein the interior face is generally convex as viewed from an axis of rotation of the receptacle, except for the concave depression formed in the interior face, and each of said retention ridges, being formed as an arcuate linear edge, converges to form an apex proximate the closed end and each retention ridge slopes towards the axis of rotation as they converge.

Abstract
A tool for torquing threaded fasteners includes a socket body having formed therein a fastener-receiving receptacle with an axis of rotation, the receptacle having a plurality of interior faces arranged in a generally polygonal configuration and substantially parallel to the axis, with each of the interior faces having projecting laterally inwardly therefrom a pair of fastener-engaging surfaces with inner and outer ends spaced apart in use substantially axially, each fastener-engaging surface being arcuate and sloping away from the axis from a closed end toward an open end of the socket.

11. A tool comprising:
-
a socket having a fastener-receiving receptacle with an axis of rotation, the receptacle having an open end and a closed end an interior surface formed within the receptacle, the interior surface defining a concave depression; a first retention ridge and a second retention ridge formed on the interior surface adjacent to the depression, the first and a second retention ridges each having a first end adjacent the open end and a second end adjacent the closed end and each being formed as an arcuate linear edge which converge at their second ends to form an apex proximate the closed end; wherein the interior face is generally convex as viewed from an axis of rotation of the receptacle, except for the concave depression formed in the interior face and the first ends of the retention ridges are spaced radially further from the axis than the second ends of the retention ridges, so that the fastener received in the receptacle is engageable by the first and second retention ridges and not by the concave depression. - View Dependent Claims (12, 13, 14, 15, 16)
