The screws, bolts and nuts all are type of fasteners characterized by their shapes and sizes. These are the basic hardware items used in almost every industry where the need of fasteners arises. These fasteners have become vitally important in every industry because of the basic but important purpose that they serve. The most basic of all fasteners is likely the simple and but invaluable screw. These screws are most commonly used to hold the objects together and to position the objects. From furniture crafting and manufacturing to building constructions, these are used as an important tools just to hold everything in place. The components used in machinery and vehicle are completely dependent upon the that has ability to hold it together.
With the beginning of screws, an impressive variety of fasteners has risen and meets the needs of today's aerospace, energy, computer, medical and petroleum industries. Bolts, nuts and screws are used to mechanically connect things together. Mostly the have threads as a part of their design and similarly can be seen in nuts, bolts and screws. Primarily are produced form ferrous materials such as carbon and steel alloys and are available in copper, brass and stainless steel.
The first screw was invented by a Geek named Archimedes, to pump water in a better way. He produced a giant screw inside a hollow tube, as when turned the screw, would water draw up. The basic shape of screw was very functional and by the first century, people started producing hand- made wooden screws. The transition of the screw material from wood to metal completed the process of makingas a main component in manufacturing advances. And by the 18th century, the world saw fasteners with strength and consistency of production.
Today we have reached a stage where a nut from one company, bolt from another and screws from other one can fit perfectly together. The reason behind this perfection manufacturing is the availability of these in standard and metric sizes for specific applications to fulfill the wide variety of industry needs. Huge variety of screws and other fasteners are available including tapping screws, nuts, bolts, cap screws, flat washers, pins, machine screws and locking washers and with the availability of those categories, the combination of material type and options make the total number of unique products almost in endless varieties. Easy to use, lighter and stronger are some of the obstacles that are facing by the fastener industries and managing successfully as well.
With the slowly but surely increasing demand of fasteners, new and innovative fasteners (snap and smart fasteners, new generation fasteners) are flooding the market like never before. In addition the internet has also increased the number of wholesalers in the market and also improved the sale of fasteners all over the world. The innovation in fasteners production can be simply seen yet vital fasteners are continued to be used as the precision needs of high tech industries including medicine and aerospace. The importance of fasteners can be easily imagined, with the realization that the thousands of varieties are being produced and we use on everyday basis.
