DIN 603 Bolt To Avoid Misalignment Method

In the use of DIN 603 bolts and nuts, a common problem is the occurrence of misalignment. So in the production process, how do we avoid misalignment? Let’s take a look at it.
In the symmetrical DIN 603 bolt and nut product, a symmetrical positioning hole can be installed to prevent misalignment during bending. When bent, the matte side of the DIN 603 bolt and nut product should be directed as far as possible in the direction of bending, so as not to tear the burr by tension. If not allowed, a process hole must be provided to position it. Rolling edge is also a special shape of the inner diameter of the curved hole. The thickness of the material of the rolled workpiece should be larger. The inner diameter of the thicker part should be larger. Generally, d>1.5 can be used. It is not necessary to set the center line of the crimping on the center of the metal sheet. If the plane of the metal sheet is placed at the tangent position of the cylinder, it is economical to manufacture.
Therefore, the DIN 603 bolt and nut can be used in these ways to avoid misalignment and ensure good performance.
