With adjustable stop to achieve optimum magnetic contact with the screw head, the height of the extra-strong ring magnet is adjustable. The ring magnet also acts as a depth stop. The stable connection between the screw and the bit holder makes accurate positioning of the screw possible, and prevents the bit from slipping and the screw from falling down. This results in significantly improved productivity and saves both time and money.
