Abstract
A spring screw assembly includes a screw, an inner tube having a spring mounted therein, and a retainer tube being covered by a color coat. The inner tube is axially movably assembled into the retainer tube, and the screw may be extended into the retainer tube and the inner tube to extend through the spring with a rack portion near an upper end of the screw tightly engaged with an upper open end of the retainer tube. Therefore, screws of different sizes and retainer tubes with different color coats may be separately kept in stock, and screws meeting customer specifications may be assembled to retainer tubes having colors meeting customer color management system at a later time to complete the desired spring screw assemblies.
