Abstract
A tool attachment for holding a fastener to a driver therefor comprises a magnetic holding assembly to which are attached spring fingers for grasping a fastener. The construction of the magnetic holding assembly provides for attachment of the device to elongated shafts of various shapes and sizes. The magnetic holding assembly is particularly characterized by an elongated, centrally-disposed pole piece which extends in the same direction as the axis of rotation of the shaft of the driver tool, when the attachment is in place. Magnets are attached to opposite sides of the pole piece in like-pole to like-pole relation, and the holding force so provided is quite high.
