Abstract: An accessory (10) for a wrench socket (12) is disclosed including a generally cylindrical magnet (32) secured to a generally cylindrical, nonmagnetic, disk (26). Accessory (10) is held within the socket (12) by snugly fitting the disk (26) formed of compressible material within the well (14) and/or by the magnetic attraction of the magnet (32) with the socket (12). The accessory (10) is removably insertable into the socket (12) of any design and model and without need for modification of the socket (12) and captures a spark plug (100) slideably received in the well (14) of the socket (12) to magnetically hold the spark plug (100) captive in the well (14) as the socket (12) is moved to the fastening location while not magnetizing the socket (12) or the spark plug (100) sufficiently to be detrimentally magnetically attracted to metal adjacent to the fastening location.

Specifically, the connecting nut (112) and insulator (104) of the spark plug (100) are insertable through an axial bore (70) formed in the disk (26) for access to the magnet (32).

Abstract: An accessory (10) for a wrench socket (12) is disclosed including a generally cylindrical magnet (32) secured to a generally cylindrical, nonmagnetic, compressible disk (26) which snugly fits within the well (14) and magnetically insulates the magnet (32) from the socket (12). Specifically, the magnet (32) is received in a frustoconical recess (46) formed in the disk (26) while its temperature is elevated allowing the disk material to flex and stretch during the insertion of the magnet (32) into the recess (46). The magnet (32) is nickel-plated (43) and its corners are beveled (41) for ease of insertion of the magnet (32) into the recess (46). Air is received within a pocket (51) extending from the recess (46) and/or vented to the atmosphere through a vent hole (53) as the magnet (32) is forced into the recess (46).

Abstract: An accessory (10) for a wrench socket (12) is disclosed including a generally cylindrical magnet (32) secured to a generally cylindrical, nonmagnetic, compressible disk (26). Specifically, the magnet (32) is received in a recess (46) formed in the disk (26) and secured to the disk (26) by a layer (60) of a size larger than and extending over the face (36) of the magnet (32) and integrally secured around its entire periphery to the face (44) of the disk (26). The disk (26) snuggly fits within the well (14) and magnetically insulates the magnet (32) from the socket (12). The magnet (32) has a size smaller than the well (14) and is generally concentric within the well (14), with an air space being created between the magnet (32) and the well (14) for magnetically insulating the magnet (32) from the socket (12) in the most preferred form.
