As mentioned above, there are many kinds and types of plugs and anchors. Let us dwell on the most popular of them. Nylon expansion plugs – record for the popularity of the application. It is used for many types surfaces. The principle of his device is extremely simple. Nylon tube having a longitudinal incision, and the screw or bolt – that's the whole design. Drill holes, dowel is inserted into it, and bursting with self-tapping vkruchennym.
Often, these anchors have extra foot for the clutch during the initial tightening screw. The fact is that sometimes, especially when drilling the walls with old loose plaster, hole gets a bit more than you need for the dowels. In these cases, additional legs do not give the dowels rotate together with screws and prevent from falling out of the hole. Nail anchors got its name thanks to the principle of installation – screw or screw supplied with it, does not require twisting, it simply plugs into the body of slaughtered like a nail. In this case, unscrew all the same it is possible. Nylon dowel-type "butterfly" is used for hollow surfaces for example, drywall construction. It has two lobes, which are attractable screws, disclosed within the cavity, thereby achieving a lasting bond with the wall or ceiling. Sometimes you can pull a plug with only around a piece of drywall.
Anchor wrought metal dowels are created and used in hollow walls, for example, block. The basic principle of operation is as follows. Through the body wall plug is screw threaded, nut which is rigidly soldered, welded or riveted to the ground. Housing dowel is a longitudinal section of a circle. Plug is inserted into the wall, and the rotation of the screw forces the body into shape, body expanded, forming something like the petals, which are being opened within the cavity, creating a reliable bond with the wall. Dowel with a spring-loaded folding emphasis is very sturdy and easy to use – before his laying in the hole, his legs folded, and after falling into a cavity in the wall, they are under the influence of springs open. Here are the basic types of anchors, the most frequently used in the repair and construction.
