<p>The present invention relates to a spring nut (1) for a profile, wherein an elastic piece (20) and a nut main body (10) are joined by a forging process wherein both sides of a seating groove of the nut main body (10) are crushed inward by the pressing force of a press mold to be attached to both upper sides of the elastic piece (20) by covering them. Therefore, the spring nut for a profile eliminates an additional process such as welding as a sealing forging part (13) covers both upper sides of the elastic piece (20), thereby allowing an automated process and significantly improving production efficiency.</p> |
