Machine screws are used in various industrial applications. When choosing a screw for a specific job, it is very important to look for a correct one. Though, sounds simple- but it is not as it seems! If a correct screw is not chosen, there may be further problems. Thus, selection of an appropriate screw is very important. There are wide array of machine screws available these days. For this purpose, choosing a screw that just help to get by the job will not be good. If the screw is too wide or too narrow, the screw will end up being in tears.
There are certain facts that need to be kept in mind when dealing with screws. The most important thing that needs to be considered is precision. The very purpose for which these screws are being used will not be solved if machine screws are unable to deliver precision. For example, these screws have more precision than self tappers with its finer threads. The metal grade that is used in these screws should be high. This will help is making screw heads much more, harder and it will be a long time when they start wearing out. These screws are basically designed for all those situations when they need to be fastened or unfastened repeatedly. In situations, where they are exposed to extraneous factors and conditions like weather, it is better to use screws that are made from stainless steel material. Such type of screws is commonly used in railway industry. Here, they are used to shut an electrical panel.
Since they are quite sturdy, there is no need to take extra care when they are being used, the major issue arises when they are over tightened. This is because they are made using a hard metal and when they are tightened or screwed, the thread may get stripped easily. This issue becomes a major concern and when screws are used for fastening control panel, it can result in requiring new thread in the panel. Sometimes, the panel needs to be undone when thread gets crossed or you may not be able to tighten the screw in a proper manner as the thread gets stripped.
Instead of using self tapping screws, the use of machine screws should be avoided. This is because both are meant for different jobs, they cannot be used for each otherâEUR(TM)s job. Usually, screws are used and designed so as to screw caged nut or a nut in panels. It is very important to take care of exact screw length and correct choice of thread. If either of the things are not correct, the job may not be done in a proper manner. Thus, precision in screws is vitally important.
