FIELD: construction.
SUBSTANCE: combined washer is used, comprising two parts: one part provides for the possibility to comparatively easy remove nails, the other (replaceable) part provides for the possibility to use nails of different thickness (different diameter). These parts represent solids of revolution, which have a central hole and interact to each other along conical surfaces when driving nails. The upper part of the combined washer is replaceable and is selected depending on the nail diameter. The lower part is shaped and provides for the possibility to "pick" it with a tool (nail drawer). In order for the set of two parts of the combined washer and the nail to stay together, rubber washers are used.
EFFECT: possibility to relatively easy remove nails so that washers could be used repeatedly and so that they are suitable for nails of different thickness.
