| 摘要 |
<p>The invention relates to a method for producing an attachment element (R) comprising a shaft (100) having a first end provided with a head (200) and a second end that is intended to be deformed in order to form a button (300) providing a bearing surface opposite the surface formed by the head (200), said shaft (100) having a nominal diameter (D). The method is characterised in that the element is sized such that the minimum length (L) of the shaft (100) to be deformed to form the button (300) is no less than 1.25 times the nominal diameter (D) of the shaft (100). The invention is suitable for use in the production of attachment elements, such as rivets.</p> |
