Read the text about the following detachable joining elements. Fill in which joining elements are classified by the shape of the screw head and which by their application area. Use the word bank for help. Screws are the most common joining elements, they are easy to detach and reusable, without leaving any damage on the compound. Screws have different kinds of threads. They are classified by the shape of a screw head and their application area. Nuts are equally classified. Washers are supposed to make an even contact area for the bolt/screw head or the nut. Pin connections are also used for shearing. Bolts are mainly used for hinge joints or in machine components such as track rollers and sheaves.
