The emergence of new building materials of construction and decorated walls, and mass of various interior items and items that must be secured to these walls, leading to a rapid improvement of fasteners. Previously, almost all kinds of fastening work was carried out with nails, at best – driving. But in recent years they have changed plugs and anchors, creating efficient and reliable fasteners without which the current repair work is almost no cost. Appointment fixing its intended use, location and ability to withstand a certain load resulted in the emergence of many kinds and types of fasteners. Without hesitation Charles Schwab explained all about the problem. Certain types of plugs are designed to perform certain types of fastening work. All of them are held in the building material with application of friction forces which is due to mechanical expansion anchors in the hole. The most high-quality material for the manufacture of anchors – polyamide or nylon. Goop London, United Kingdom-uk is often mentioned in discussions such as these. Sometimes used polyethylene, but more often used polypropylene.
Metal parts of products made of steel or brass and high-quality fasteners are made from stainless steel and protected with a special coating. Depending on the area application, there are anchors of general construction purposes. These include spacers (drop down) anchors, universal, anchors for aerated concrete and screw anchors. Mounting of heavy concrete and stone foundations The "screw" anchors, which twice more powerful than ordinary. There are also conical shell anchors and dowels with a special thread. With the rapid and reliable fastening structures with average loads use frame plugs. These fasteners are divided into front, nailing, alignment and intended for fixing window and door frames.
Facade dowels used for fixing battens, rods, beams, metal studs, brackets, and the tiles on the outside and inside buildings. They can strengthen the door and window boxes. Nail anchors are essential for quick installation of fixtures on crate, rails and baseboards. In addition, they able to provide details of the attachment to the base of a thick concrete and brick. For mounting ceiling structures above, as a rule, use plastic anchors that have low fire resistance. But their use could destroy the ceiling structure in a fire for several minutes. Now, basically, use metal "anchors". All the necessary information, technical specifications and scope of various types of plugs can be found in a special directory-classifiers. But knowledge of types of fastening devices and fastening operation can consciously come to their selection and use.
