发明名称 Magnetic wrench attachment
摘要 The present invention is an attachment that fits onto the head of a wrench to magnetically hold a nut. The attachment has a magnetized surface and a side surface to friction fit onto a wrench. Fit is further improved by magnetizing the side surface. By holding the nut, the attachment allows for operation of a wrench in restrictive spaces where manual holding of the nut would be impossible or impracticable. Making side surfaces of the attachment out of plastic allows the attachment to adapt to different sizes of wrench heads. A hole in the attachment allows a bolt to pass through the attachment as it passes through the nut.
