Oblong hole

An oblong hole refers to an elongated hole or slot in which the long sides run parallel and the narrow sides end with semicircles whose diameter corresponds to the width of the oblong hole. Oblong holes can be linear or radial. The oblong hole is a useful component to enable movable mounting types and machine parts fixed adjustably to each other. Thus, it can be useful for adjustment or compensation of tolerances. Slotted holes can be used to safely move assembled parts within a given frame. They can also help to save material. However, care must always be taken when using slotted holes to ensure that the correct position of the components is not jeopardized due to loose connections. Oblong holes can be produced by a wide variety of manufacturing processes such as milling, casting. Cutting or punching.
