lautasmutteri

Lautasmutteri is a Finnish term that translates to "dish nut" or "plate nut." It refers to a type of fastener, specifically a nut, designed with a wide, flat flange or base. This flange distributes the load over a larger surface area compared to a standard hex nut. This characteristic makes lautasmutteri particularly useful in applications where the material being fastened is soft or brittle, such as in sheet metal or plastic. The wide base helps prevent the nut from digging into or damaging the material.

These nuts are often used in conjunction with bolts or screws and are commonly found in automotive interiors, appliance manufacturing, and furniture assembly. The flange can also provide a decorative element, acting as a washer and a nut in one component. They are typically made from metal, such as steel or brass, and can be plated for corrosion resistance. The design aims to improve the holding power and prevent deformation of the workpiece. While the term is specifically Finnish, the concept of a flanged nut is universal in engineering and manufacturing.
