A few years ago, we are confident to say that it could be a nail or screw, but also in the first and second has its advantages and disadvantages.The highlight of the rapidly mounting produce, but it does not provide structural strength and eventually it may simply fall apart.The screw imparts structural strength, but due to the inconvenience in mounting the speed is lowered.Therefore, this problem is solved screws, anchors, dowels and screws.They are connected and the speed of installation, and the strength of attachment, as a specially selected step and the angle of the thread, as well as provide them with the tip of a quick fit and strong and reliable connection.Furthermore, they have a corrosion-resistant coating, which allows increase lifespan mounting, and hence the reliability minutes durability of the whole structure.

Frame fasteners for fixing bars, wood and construction strips, facades, window frames and metal profiles.

General purpose fasteners are used for light fixtures, as well as v
arious types of hooks for attaching forests, ropes, cables, chains.In addition, the retail chain has a mount for sanitary equipment, light and heavy building structures for insulation materials and others.

self-drilling screws used for fastening sheet metal to heavy structural and sheet metal together (overlap), as wellsteel and wooden bases, installation and finishing works.It can be used in furniture manufacturing.

screws roofing used for fastening profile metal sheet to a tree, a light steel structure, or between.a (lapped).

hardened screws are designed to connect wood, chipboard and plasterboard as well as for thin sheet metal.

Screws for mounting plasterboard used for fixing plasterboard to the profiles of sheet metal elements made of wood, as well as for rolling sheet metal profiles.

Screws for mounting window profiles used for fixing plastic and wooden profiles and other assembly work.

Fixing wood

strength and stability of any product or structure depends on what is used fastening, connecting into one part of wood takes an exclusive place thanks to the ease with which it made of the elements can be interconnected differentlyshaped fasteners - nails crutches, adhesives, screws, straps, dowels, screws and others.

strength for fixing the product or construction joints should not be selected randomly, and must meet the properties assigned to this product range along with the fastening of the pope or the rivers of the fibers, andas time changes in the sizes of humidity fluctuations.

Nails. nails - the most common type of fastening to building structures and wood products.Construction nails are available in two types: flat and conical head.

Nails are made of light low-carbon non-hardened steel wire Noah cold stamping.

Construction nails round (rarely square) cross-section in the joinery used in length from 7 to 90 mm and a thickness of 0.7-3.5 mm.

Round nails used in the installation cabinet walls, panels barriers.Applied also pin - thin nails without hats that attach lining, layout rods.Connecting the main parts of these products made with glue, less screws.

Tolev nails length from 9 to 40 mm, thickness from 0.8 to 2 mm is used for the upholstery of tar paper collected window and door units, cone beams, wooden structures comes into contact with the walls.

Decorative nails designed for facial furniture surfaces, especially soft.They are available with round, square and shaped heads, which can be smooth or embossed with cast ornaments.Dimensions head diameter or side of the square - 6,8,10 and 12 mm.Stem length of these nails is not more than 30 mm.When nailing into the timber (wooden mallet) their heads should not jump to the bar, there should be no dents, distortions, or delamination of the decorative layer.

resists pull out nails and lateral (shear) loads or joint action of the two types of loads.The resistance depends on the properties of wood and nail conditions of use.Nails, like other fasteners like staples and T - nails should be placed so that the connection works primarily in shear rather than peel to nails experienced mostly lateral loads and working on pulling.Resistance shank of the nail pull-out of the wood depends on the density of the wood, the diameter of the nail and the degree of penetration.

resistance nails pull-out greatly influence factors such as the type of tip, the type of rod coating nail Time Spent nails in the wood and wood moisture change.

have the greatest resistance to pull-out nails hammered perpendicular to the grain of the wood.When the hammer nails along the grain, ie. E. In the end, pull-out resistance for softwood is 75 or even 50% of the resistance during pile across the grain.

Crutches .Conventional crutches wire manufactured in the same way as wire nails.Their tip has the shape of a tetrahedral pyramid length 76-305 mm, the length of the diameter larger than that of ordinary wire nails.

Bolts are used to connect parts, especially widely used in their bent furniture.To protect the wood from buckling when screwing the bolt under its head enclose washers.

Screws made of low carbon steel or brass wire.Dimensions screw length - from 6 to 120 mm, the diameter of the rod - from 1.5 to 10 mm, the diameter of the head - between 3 and 20 mm, threaded part of the rod should be no less than 0.6 the length of the screw.Screws connect the parts of the product when the area for the bonding is insufficient in size, for example, bent furniture used metal screws for mounting devices and accessories for, furniture and joinery products.For convenience, screwing his head has slotted groove (slot).Screws distinguish countersunk, countersunk and pan head.

for screwing flush with the surface of the wood is most often used with flat head screws.Screws with a circular or oval head is used in cases when it is necessary to give the wood surface a nice view or if the screws are countersunk screw is undesirable.The main parts of the screw - a screw thread and rod.

Modern trends include the use of wood mounting screws threaded tapping along the entire length of the rod.Commercially available screws in some cases, have certain advantages.

pins .It is assumed that the pins are scored in a pre-drilled holes with a diameter of 3.2 mm less than the diameter of the pin, provide a good connection.Side load pin, hammered across the grain of the wood must not exceed the maximum load cut rod of the same diameter.To compensate for the lack of washers and nuts, pins are longer than ordinary bolts.

Staples .There are several types of staples differing shape of the tip, the rod treatment, type of coverage, caliber, length and diameter.These mounts are available for use in pneumatically operating systems with clamps or tape.Use them in the upholstery.

Ā«CapercaillieĀ» - large screws length of 35 mm and a thickness of 6.O mm with a square or hexagonal head adapted for screwing grouse key.Furniture grouse have a square shape with a broadened base, which serves as a washer, avoiding crushing the wood when screwing grouse.

Squares metal used for additional fastening parts angle joints. pads are straight metal plate with holes for the screws: they are fixed on one or both sides of the bar (parts) in areas of insufficient strength or the fracture site.

to connect the pieces of furniture are disassembled metal ties .There are overhead and locks.

Shelf support serve to maintain Adjustable shelves in the cabinet (cupboard) furniture.They are metal pin "with attached angles.To attach metal shelf support oboymochki to the pins (caps).Oboymochki firmly inserted into the socket, drilled on the inner sides of the walls of the enclosure.They protect the wall socket of the shear pins Shelf.

Hardware.Hinges called hardware, as well as other accessories for windows, door (wrapping latches, handles, locks, etc.).Typically, hardware made of light carbon steel.Facial devices varnish, chrome, nickel.

window and door hinges are used for mounting door panels and window sashes, for lifting and lowering;opening transoms and vents.

By design card hinges are distinguished: the hinge with a removable hinge bar (Bout), pivot the rod embedded in a card fixed, hinged to the rod is not removed from the joint, and vkolotnye.

hinges with removable rod used where wooden casement or leaf can not raise that to stay with the fixed hinge bar.

pintle hinges are applied to wood panels and flaps.

hinges with hinge pins are used for small casements, transoms, panes.

Card loop selected taking into account the size of panels and shutters, the thickness of strapping bars.

Each loop consists of two cards with the hinge.The card consists of a steel plate at one longitudinal edge of which are made to cut down, and got this from the projections are bent to form a hinge (podgibnye map).

from the longitudinal edge maps to the heel side edge of the bar of the door leaf or flap should be a distance of 6-11 mm depending on the size of the bars.

Vkolotnye loop is used for mounting the valves binding and paintings balcony doors with the influx.

In public buildings with a large flow of people opposing door panels hang on double leaf spring hinges for opening doors on both sides.There are loop left and right, depending on the sample door sashes.

handles for doors and windows is a great variety.There are door handles, doors, balcony doors.Buttons instead of knobs used only for interior doors.

Latches - is keyless locks.There are door and window latches.Door latches crashed into the left edge of casement cloth on double door.Overhead door latch has a length of 370 mm, the bottom - 230 mm.You must install them without skewing and jamming.

Mortice locks or overhead made only at the door.In the market of building materials and products used principally new mechanical locks with a plastic key card.Locks of this type have the possibility of multiple conversion and formation of branched system of authorized access.

Opening made easy by pressing the key-cards, and closing - without using a key.

Window latches, upper and lower, have a very simple device.These incorrectly called latches.For keyless constipation also include door and gate fortochnye different devices and hooks.

to instruments contributing to closing the doors are spring linkage-less, with the lever, pneumatic.

Currently, the distribution network in a wide range of products includes devices for windows and doors in the main aluminum alloy with anodized finish, which improves their appearance.

Furniture accessories depending on the type of appointment and the material features a large variety of furniture, including the artistic decoration for her jewelry.

materials for fastening carpentry construction

For fastening of wood products to the walls and interconnecting wooden structures used ruffs, crutches, braces, straps, clamps, anchors, and others. They are called forgings.

Construction forgings made of forging, mild steel (iron), most of it is forging products.

Rag bolts are used to fasten in the openings kamnevidnyh walls of windows and doors, walls at the junction to the walls.The pointed ends of the ruff hammered into a wall-mounted wooden antiseptic or plastic plugs.It blocks box ruffs nailed through ershah available in your ear.Crutches are used for hanging on the wall kamnevidnye cornices, paintings, chandeliers, etc. Having broken jumper or drill a hole, put the cork back and pierce the bone.

brackets are used to mount additional compounds notching the rafters and mauerlat.Depending on the location of the connections of structural elements, they are straight and angled negotiable.They are made of steel bars of circular cross section diameter of 10-12 mm or kvadratnogo-.10x10 and 12x12 mm.

pads used for fastening composite beams and lower belts of farms and arches.They are made of thick rolled steel.

bolts used to fasten composite beams, attachment to the foundations of frame and panel walls, and others. Bolt holes drilled electric drill or lay the foundation by pouring.

Yokes tightening and tightening serve to bond dense beams of logs or boards in the cobbled and timbered houses, fixing bars.They are made of flat steel section of 4x60 mm.

Anchors - a steel parts of flat steel section 4x40 mm T-shaped lengths.Used to connect wooden beams with a stone wall.The most common sizes of 400x720 mm.

to connect the wooden beams with concrete anchors runs using T-section length of 500 mm.Curved ends of the anchor engaged with the brand runs.

clamps are made from scraps of steel and is used for fastening sheets of galvanized steel, for fixing the ribbon tiles.There are different types of capping.For example, one end of cropping steel, nailed crate when the roof, another fixed standing seam roofing galvanized steel.Clamps for fastening the tiles allow to mount just two tiles as follows: a horizontal flap falls over the capping tiles laid, and by its vertical flap, about other adjacent tiles.Klyammernye hooks clog from the attic in the crate.

Galvanized screws size 5x60 mm or 5x70 mm round head are used for fastening corrugated slate.To mount the auxiliary asbestos-over take a screw size of 5x40 mm semi circular and flat head.

for roofing and construction using roofing nails roofing nails have a diameter of 3.5 mm and a length of 40 mm.A variety of construction nails allows you to select the nails in the following range: diameter 2.5 mm, length 50 mm or 60;diameter 3 mm, length 70 and 80 mm diameter 3.5 mm, length 90 mm;4mm diameter, length of 100 and 110 mm and a diameter of 5 mm, length 150 mm.All nails are fastened piece materials.

So, for asbestos-cement flat slate used nails with a diameter of 2.5 and 3 mm and a length of 35 to 40 mm respectively.For corrugated asbestos cement sheets take the nails with a diameter of 4 mm length of 30 mm.For wooden roof (shingles, shingles, shavings) used nails of 2.5 mm, a length of 50 or 60 mm.Shoring "planks nailed diameter of 4 mm and a length of 10 mm.

wire is used as fasteners and pressed ridge tile. It is used together with nails with a diameter of 3-4 mm and a length of 40-50 mm. Nails hammered 2/3 the crate andfor the rest of the outside of the nail wind the wire, which is tied to the other end of the thorn tile. Use a steel wire with a diameter of 1 mm from the copper - 2 mm, and aluminum - 2.5 mm. Before fixing tiles copper and steel wire covered with oil paint, so it does not
