Flat Head SuperMag Magnetic Bit Holder, Accessory

Unlike most magnetic bit holders which use a single magnet to magnetize the driver bit, the SuperMag Bit Holder will save you time and hassle with a second ring magnet that surrounds the driver bit. The ring magnet pulls the screw head tight against the face, basically locking the screw in place. The adjustable collar threads onto the holder body for perfect positioning of the second magnet and proper engagement of the driver bit. Designed to fit flat head screws and can be used with any -1/4” hex shank – 1” long insert driver bits. Top portion made of Stainless Steel. Available in 2-3/8”.
