5/16" Impact Nut Driver

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.
