Abstract:
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, with the well slideably receiving a spark plug, with the spark plug including a body having a threaded portion and a nut portion, with the spark plug further including an insulator extending from the body and terminating in an electrode disk against which a connecting nut abuts, with the electrode disk being formed of magnetic material, with the accessory preventing the spark plug from sliding from the well to hold the spark plug captive in the well while the socket is being moved relative to a fastening location, comprising, in combination: a magnet having, a periphery smaller than the inner periphery of the well; and a nonmagnetic disk including opposed, first and second faces, a periphery, and a recess for receipt of the magnet and extending at a depth from the second face of the nonmagnetic disk towards the first face of the nonmagnetic disk and spaced from the periphery of the nonmagnetic disk, with the periphery of the nonmagnetic disk being adapted to pass into the inner periphery of the well, with the nonmagnetic disk including an axial bore of a size for slideable receipt of the connecting nut and the insulator of the spark plug, with the magnet being proximate to the connecting nut when the insulator is received in the axial bore of the nonmagnetic disk.
