Sokeareikä

Sokeareikä is a Finnish term that translates literally to "blind hole." In practical terms, it refers to a hole drilled or formed in a material that does not go all the way through. This is in contrast to a through hole, which penetrates the entire thickness of the object. Sokeareikä are common in various manufacturing processes, engineering applications, and even in everyday objects.

The creation of a sokeareikä can be achieved through different methods depending on the material and desired precision. Drilling is the most common technique, where a drill bit is stopped before it exits the opposite side. Other methods include milling, punching, or even casting, where the mold design intentionally leaves a portion of the hole unfilled. The depth of a sokeareikä is a critical dimension and is often specified with tight tolerances.

Sokeareikä serve a multitude of purposes. In mechanical assemblies, they are often used for threaded fasteners like screws, where the thread is cut only within the blind hole. They can also be used for locating pins, dowels, or for housing components that do not need to pass through the material. In some applications, a sokeareikä might be designed to contain a fluid or to reduce material usage and weight. The depth and diameter of the hole are crucial design parameters that influence its functionality.
