What is the carriage?
The carriage is a type of threaded fastening element designed for use with wood, although the specialized versions can be used to fix metal components. Also known as screws or coach screws, carriage screws can be found in many hardware stores in the range of lengths, diameters and tones of fibers. They are usually made of different types of steel for strength and durability, although other materials can be used to produce them.
Design
The carriage screw construction includes a large round dome head with an externally threaded screw. The head is usually at least twice the diameter of the screw shaft and usually does not have slots for a screwdriver or other driving device. Under the head is a square mounting that grabs the wood when the screw is placed and fastened, prevents it from twisting or rotating and otherwise maintaining a cozy adaptation. In the variant of the pram's basic screw, square mounting under the rounded ribs that hold the screw in place when used with other metal componenty. The length of the screw itself will vary depending on the intended use, as well as the diameter of the screw and the head of the screw, regardless of the types of materials fastened.
Like the other screws, the screw is designed for use with a nut that helps secure it on site. The matrix can be tightened manually for reasonably cozy adaptation or powered by a hand tool that locks the trolley screw, ensuring that it cannot move. The size of the screw fiber must correspond to the size of the matrix fiber to be screwed correctly; The sizes of the fibers may vary significantly depending on the application. The specialized versions of the combination of screws and nuts can be made of metals such as galvanized steel that can withstand corrosion to be used in wet environments or where the screw is likely to be exposed to corrosive chemicals.
usually use the wheelchair bolts in the Primelipped holes; This is necessary in most cases because the screw cannot be introduced by its round smooth head. Square mounting that holds the bolt in place means that the nut can be tightened firmly, but creating a fixed adaptation. The screw shaft is often smooth immediately below the assembly, as this area is completely inside the connected material and therefore does not have to be threaded. Wide head - sometimes called a cup or mushroom head - is ideal for use with wood, where its large size prevents it from being deep into the wood without the need for a pad, even if they can be used.
uses
pieces of wood are often secured together using one or more screws of carriages during house construction, outdoor deck and pillars. These screws are commonly used in the fences of chain, terraces and furniture ready to assemble, assemble machines and even in cars. Since the square mounting prevents the screw from turning, the carriage screws are a good choice for situations where the head of the screw cannot beeasily access.
When using transport screws, it is important for the application to select the right width and length screw. Too narrow screw can lead to failure under voltage, causing the object to break. If the carriage is too large, it can emphasize the surrounding wood or metal, causing cracks. The length is also important, because the screw must be long enough to undergo a material that is fastened, but not so long that the protruding end becomes annoying.
