Abstract
A screw band can hold screws of different diameters, having a body of any length provided with notches in two longitudinal sides for the band to be moved by a screw driving tool. The band has plural screw holes respectively defined by an annular wall extending down from the band. The annular wall has plural small notches for screws to be driven through the screw holes smoothly. Plural valves extend inward from an inner surface of the annular wall for supporting a screw planted in each screw hole. The valves may be any type and may bend to form a contact-with-each-other condition or a non-contact-with-each-other condition and to produce elasticity for securely supporting a screw of different diameters.
