FIELD: machine building.SUBSTANCE: fastening units, elements for fastening units and methods to manufacture and assemble elements for fastening units, for instance, for fixation of an insulating coating used on airplanes, may include a solid metal configuration, having the first and second side sections with multiple retaining elements to retain panels arranged linearly along the side sections. A flat retaining element, for instance, a disc, may be assembled with a metal section to form the fastening unit, which may be used to retain the insulating coating. The flat retaining element may include a rounded edge, and when using a process of coating application, may include ledges on the surface to prevent sticking of adjacent parts in process of coating application.EFFECT: manufacturing of a fastening button as more reliable, providing for higher service life under difficult operation conditions. |
