Rivets are used either for decoration or to join two or more layers of material. A rivet consists of two parts, an upper part and a lower part. The lower part has a "stick" - This is the part we call the body. We call the upper part the head, on the back there is a "collar".

The size of a rivet is given in millimeters and should be read as follows. For example, "str. 7 x 9”. 7 indicates the length of the rod/body and 9 indicates the diameter of the rivet head.

When choosing rivets, it is important that you choose the right size. When you have to choose the right size, it is the length of the rod that determines, i.e. the lower part. It must be 2 – 3 mm longer than the thickness of the material it must pass through. This means that when you have inserted the lower part, the rod must stick out 2-3 mm.
