Choosing the right Screw For The Job
There are many different types of screws, when buying them what is most important is that the type of screw matches the demands of the project being undertaken, many screws are designed expressly to satisfy the demands of a given application. It is also important to give consideration to the material that the screws in NY are made from; this will ensure that the appearance expectations are met as well as being able to stand up under severe climatic conditions. Some screws are fine for use in a number of applications, drywall screws are typical multi-use screws however there are other screws that are largely unsuitable for anything other than what they are designed for; self-tapping screws are a good example.
Of all the various screws available perhaps wood screws and drywall screws are most common. Both of these screws can be used when the task is to fasten something to a wooden board surface. Wood screws are manufactured with a sharp point and are usually large in diameter vs. length. A wood screw normally is started in a small diameter pilot hole while drywall screws which are smaller in diameter for their length have courser threads and require no pre-drilled pilot hole.
Screws in NY are also used for fastening metal together. A very typical screw is one designed for use with sheet metal, these screws have a close pitch so they can grab thin sheet metal and till hold firm, they also have flat heads so that they do not protrude above the surface once they are firmly driven home. A typical self-tapping screw is somewhat like a sheet metal screw but they have sharp point that drills its own hole. Self tapping screws are ideal for use with soft meal such as aluminum sheet.
There are other screws that are made for very specific purposes; good examples are screws with hooks or full circles on the end. These screws are designed purposefully for use in hanging an object such as a picture frame or kitchen utensils.
Regardless of the application it is very important to pay particular attention to the base material as well as the final finish. In the majority of cases mild steel is used for the screw and the finish is zinc plating. While these screws are common, screws are also available in stainless steel and brass, both of which are ideal for use in corrosive conditions where other screws will quickly rust.
