But children, unlike us do not know what all this together is called the fasteners. Nails. Their types and scope of Common nails are made of crude steel, and even of steel wire (soft). They are labeled by two numbers: the first indicates the diameter of the rod, the second - the length in millimeters. They have a flat smooth or ribbed hat. Wire nails with a flat head is used when the need to hide her hat. Hammering a nail through Race Seat, you can prepare the surface of the board for further fillers. Grooved, screw, nails and Clubs ershi for mounting the paintings have a rod with longitudinal, transverse, helical grooves, dents, or burrs. They have more resistance when pulling out. Nails from heat-treated steel (hardened) can score in the brick walls and even the lightweight concrete. But these fragile nails that need to be considered in dealing with them. Plastering, Tolev, wallpaper nails used for fixing maloprochnyh materials to the hard ground. They have a shorter stem and a broad flat hat. Depending on the environment, which will be used in a nail, it can be: · galvanized · copper (less prone to corrosion) · stainless steel (no rust at all). Driving nails - is a science kind of encyclopedia of the process of nailing developed a German specialist Frank nipple. Here are some tips that may come in handy during pile of nails. 1.

But it all depends on the proper selection of type and size. Screws are used in particular for working with wood. They have a tapering rod, acting as borax. Screw does not clog and twist until the end of its full length. Under the small screws make the puncture with an awl, a large can be pre-drilled holes with a diameter smaller than the diameter of the fixings minus the thickness of the thread of his carvings. Screws are used, inter alia, for connecting metal structures. The screw head is used for pressing the joined parts and the seizure of the screw with a screwdriver, wrench, etc. Common standard mounting screws, hex, flat, semicircular, etc. heads. Butt Screw flat and has a chamfer to prevent entry of thread damage. Screw threaded into the threaded hole. The size of the diameter of the screw thread pitch should conform strictly to mate (nut, the hole in the body parts with internal thread). At the end of the screw sometimes make the hole for the pin - wire rod semi-circular cross section, bent almost in half. Cotter pin prevents the fasteners from the spontaneous unscrewing the nut. Between the nut and the workpiece put the puck with an inner hole, allowing the free passage of the screw rod. It is easier to remove rusted bolt These screws are extracted using a special firing pin or swage. In some cases it is expedient to heat the nut with a blowtorch or a gas burner. If the use of open fires is unacceptable, you can use a big hammer soldering iron or even a red-hot iron rod.
