Kiinnityshylsä

Kiinnityshylsä is a Finnish term that translates to "mounting sleeve" or "fixing sleeve" in English. It refers to a type of mechanical fastener or component used to securely attach or support another object. The specific design and application of a kiinnityshylsä can vary widely depending on its intended purpose.

In construction and engineering, a kiinnityshylsä might be a hollow cylinder, often made of metal or plastic, that is inserted into a pre-drilled hole. Screws, bolts, or other fasteners are then passed through the object being mounted and into the kiinnityshylsä, creating a strong and stable connection. This is particularly useful when mounting to materials that are not strong enough to hold a screw directly, such as drywall or softer types of wood. The sleeve expands or grips the surrounding material, distributing the load and preventing pull-out.

Another common use for kiinnityshylsä is in the context of shafts and bearings. Here, it can act as a spacer or a component that allows for precise positioning of a shaft or other rotating part within a larger assembly. It might also be used to adapt a shaft of one size to fit a bearing or housing designed for a different size. In some cases, a kiinnityshylsä can also serve as a protective element, shielding a shaft from damage or wear. The term encompasses a broad category of components, all sharing the fundamental function of providing a secure point of attachment or precise positioning for another element.
