Information Regarding Screws Used In Today's World
The screws, which are so prominently used today in construction, manufacturing and many other things have an interesting history. Archaeological digs have found evidence that they were used by the Greeks about the 3rd century BC. These were wooden, and it was not until the 15th century, in Europe, that the original metal ones, forerunner of those in use today, appeared.
Devices to turn the screw, screwdrivers, were also in existence in the medieval times. However, they did not gain much use until after 1800 when the so-called 'threaded fastener' came into use. Machine tools and mass production lead to the abundance of this this fastening device on the market today. It is hard to believe how difficult building must have been before the development of these tools.
This very important part of any construction project is generally made from low to medium steel wire, however other metals such as stainless steel, nickel alloys, brass or aluminum may be substituted. The quality of the contents used in its construction is important as some are designed for use, with special materials, for various situations. Stainless steel, used for many things, is often used in medical surgery when rods and other items are permanently installed in the human body.
The type of screws varies according to where they are to be used. There are wood, sheet metal, roundhead, machine, and lag. Wood screws are used on wood, sheet metal for metal, roundhead on soft or hard metals, machine (with a variety of heads) is for metal, lag units for light work such as lead or plastic. The lag models are heavy-duty and are usually driven with a wrench for fastening into masonry or wood framing.
There are specific laws and regulations that control screw threads. These include such things as the pitch and shape of the thread and well as the number of threads per inch. In addition, there are designated diameter sizes. There is a worldwide restriction on the metric and inch sizes of coarse and fine pitches.
Those designed for metal are not only used for manufactured products but for home built ones as well. An example is people who build their own storage shed or other things made of some type of metal. These are also commonly used in machine shops and other places involving metal.
The tools which are used to effectively install screws varies according to their use. They go from small screwdrivers for home use to huge machines used to install them in foundations and other locations. Some people also use a cordless screwdriver, which is run on a battery and is lightweight. This type comes in small and large units. Most homeowners use the old fashioned screwdriver which is powered by hand.
