Screws were introduced by the Greeks, millions of years ago

* Steel screws are resistant to rust. Where as, nails and other tools are non-resistant to corrosion. They ensure long term support to the texture in which they are drilled in. However, be careful about the source that you obtain them from. The two major components of a screw are: The head and shaft. Even if you find rust gaining ground on the head (which is exposed to air), the shaft would remain unaffected. This instrument is designed in such a way that moisture or contaminants find it difficult to penetrate through the surface. * These tools come in a wide array of variety. You may use them on wood, drywall, metal or even concrete. There are bolts designed for use on every texture. So, you can get fasteners in any form, size or shape now. The various types of designs available with manufacturers help you get optimized results. * Replacement or removal of these fasteners is comparatively simpler than that of other ones. If you talk about nails, once you detach them, you would also harm the surface with which it was attached to. But screws are easy to pull out. You just need to twist them out with the help of a screw driver. Pushing in another one is also a cakewalk as you would not have to imply huge amount of strength. While dealing with manufacturers, look for value added services like: same day shipment, and discounts on purchases over a certain limit. Contact experienced service providers who have been around for at least a decade now. It is because perfection shines with experience!
