Magnetic keeper accessory for wrench sockets

Claim 1

Accessory for use in a wrench socket without need for modifying the wrench socket, with the wrench socket being of a conventional design including a well having an inner periphery formed by multiple sides intersecting at outer corners and including a handle mounting end, with the well slideably receiving a fastener, with the accessory preventing the fastener from sliding from the well to hold the fastener captive in the well while the socket is being moved to the fastening location, comprising, in combination: a nonmagnetic, compressible disk having planar, parallel, opposed, first and second faces and a periphery having at least portions of a size greater than the inner periphery of the well; a generally cylindrical magnet having planar, parallel, opposed, first and second faces and a periphery smaller than the inner periphery of the well, with the magnet being secured to the disk with the second face of the magnet being spaced from the second face of the disk and the periphery of the magnet being spaced from the periphery of the disk with an annular portion of the second face of the disk extending beyond the periphery of the magnet, with the disk being deformable under force to pass into and snuggly fit within the inner periphery of the well with the magnet positioned on the opposite side of the disk than the handle mounting end of the socket with the disk magnetically insulating the magnet from the socket and with the magnet positioned generally concentrically within the inner periphery of the well creating an air space between the inner periphery of the well and the periphery of the magnet for magnetically insulating the magnet from the socket.
