1. A ratchet wrench assembly comprising:
- a. a wrench having a handle and a head at one end of said handle, said head defining an opening;
b. a ratchet ring disposed in said opening such that said ratchet ring rotates with respect to said head in a first direction and rotates with said head in a second direction, said ratchet ring defining a substantially cylindrical inner engaging surface having at least one rib projecting radially inward from said inner engaging surface; and
c. a socket havinga generally cylindrical first portion having an outer surface and defining a polygonally shaped bore therein,a grip ring non-rotatably disposed and axially fixed on said first portion outer surface and extending radially therefrom a distance substantially equal to or larger than an axial width of said grip ring; and
a generally cylindrical second portion defining at least one depression in an outer surface thereof for releasably receiving said at least one ratchet ring rib therein when said second portion is inserted into said ratchet ring inner engaging surface.

Abstract
A ratchet wrench, the ratchet wrench having a head portion defining a substantially cylindrical inner engaging surface and a plurality of ribs extending radially inward therefrom. The socket includes a first portion defining a plurality of depressions axially aligned with the longitudinal axis in an outer surface thereof, the first portion being releasably received by the substantially cylindrical inner engaging surface, and a second portion including a cylindrical outer surface and defining a hexagonal recess therein. A grip ring includes a knurled outer surface and is disposed on the second portion outer surface. A magnetic insert is received in the hexagonal recess.

16. A ratchet wrench assembly comprising:
-
a. a wrench having a handle and a head at one end of said handle, said head defining an opening; b. a ratchet ring disposed in said opening such that said ratchet ring rotates with respect to said head in a first direction and is rotationally fixed to said head in an opposite second direction, said ratchet ring defining a substantially cylindrical inner engaging surface having a plurality of ribs projecting radially inward therefrom, each rib having a slot formed therein transverse to an axis of said ratchet ring, said ratchet ring slots aligning with each other to form a first annular groove; c. a ring member received in said first annular groove; d. a socket having an axial bore formed therethrough, a first generally cylindrical portion including an outer surface and defining a hexagonal bore therein, an inelastic grip ring non-rotatably disposed and axially fixed on said first portion outer surface and extending radially therefrom, said grip ring being press-fitted to said first portion outer surface and including a knurled outer surface, a second portion defining a plurality of depressions in an outer surface thereof for releasably receiving said ratchet ring ribs therein when said second portion is inserted into said ratchet ring inner engaging surface, said second portion outer surface defining a second annular groove that is positioned to align with said ratchet ring first annular groove and releasably receive said ring member when said second portion is inserted into said ratchet ring inner engaging surface; and e. a magnetic insert having a plug including a base and a stem extending therefrom, said stem being received in said axial bore and a magnet received in said base, said bore being received in said hexagonal bore.
