1. Purpose and Application of Nailing and Screwing

Nails and screws are slim metallic fasteners (joining elements) which are driven in and/or screwed in, in order to join two or more relatively thin workpieces or prefabricated parts.

Nailed and screwed joints can be quickly made with simple means and without major constructive expenditure, under erection conditions on the site as well.

Screws are primarily used as joining elements between metal and wood, e.g. the fastening of any kind of mountings on wooden piece parts and furniture. They can be easily loosened - thus making an exchange of the structural members possible. Nails are often used as fasteners/joining elements for several workpieces or prefabricated parts wherever a quick joining of piece parts is possible.

By driving in the nail with a hammer, compressions may occur on the material surface which is not always desired.

Nails and screws can fulfill different tasks:

- as a self-supporting (holding!) joint,
- as a securing (supporting) joint together with other joints and fasteners, e.g. glue.

Nails and screws join the workpieces in one point only. To make an areal joint, it is necessary to drive in and/or screw in several nails or screws at a distance to each other as large as possible.
