Fasten parts: varieties, application

The fastener is a metal fastener that holds the structure at right angles to this base. This type of fastener is endowed with strength good characteristics so that the strength is greater, the rib of stiffness is used (between the sides of the corner a welded metal plate). The most common is a galvanized corner, which is needed in a place where there is a threat of corrosion development. Window screws — fasteners that are used to install window systems. During use, window self -tapping screws should be fixed to the wall with a sense of sufficient stiffness. You can also apply window screws for metal -plastic windows. In order for self -tapping screws and screws better to the wall, you can use nylon and plastic dowels. In all situations, plastic dowels are used and then you can be sure that the fasteners of the screw (screw) are quite strong. Plastic dowels are small cylinders and a screw passes through them. When screwed, the plastic dowel bursts, thereby in close contact with the wall.
