Spyder 4-Piece Magnetic Impact Nut Driver Set (1/4, 5/16, 3/8, 7/16″) 19063

Spyder nut drivers are impact rated for demanding high torque 1/4-inch impacting applications. Powerful magnets retain fasteners for enhanced driving accuracy and one-handed ease of use. These one-piece tool steel nut drivers are engineered for use in impact drivers, and can also be used in standard rotary drills with a 3-jaw chuck. A low-profile design makes these drivers ideal for confined area use.
