With the Facom EF.6DM7L magnetic nut driver bit, you work faster and with complete control on every fastening job. The integrated magnet holds 7 mm hex head screws and bolts securely in place, allowing you to position and drive fasteners effortlessly with one hand without dropping them. Thanks to its 70 mm extended length, you easily access recessed and tight assembly spots. The standard 1/4" external hex shank with retaining groove locks securely into your drill driver or bit holder. This makes assembling sheet metal, cable trays, or control cabinets smooth and accurate.
