Metric Screws for Your Next Project
While the United States still uses the standard methods of measurement, some of your projects may use the metric system instead. When this occurs, you may need to purchase metric screws to complete the project. However, these screws aren't always easy to find, which can cause delays in your project as you try to find the right ones.
Metric Screw Head Types
One of the considerations you must make with metric screws for your project is the type of head you require. While the different heads use different types of screwdrivers, they also serve different purposes. For instance, the socket heads use special socket wrenches and work well in hard-to-reach places. If you need the screw heads to lie flat against the material surface, you will need flat heads. If it doesn't matter, button heads will work just as well.
Metric Screw Driver Types
If you are left to choose the metric screws for your project, you need to consider the types of drivers you have available. In general, metric screws come in several driver types. In addition to the typical flat-head screwdriver and Philips head, socket screws are another option. In some cases, the location of the screws will dictate the driver type you need. If the screw is in an open area with plenty of space, a flat-head or Phillips screwdriver can work well. However, if the screw is in a tighter position, a socket can reach the area more easily.
Metric Screw Materials
The final main consideration you need when selecting metric screws for your project is the material from which the screws are made. In general, screws can be made from most metals, including alloys, stainless steel and zinc. Be sure you choose the right type of screw for the material with which you are working. For instance, if you need to use the screws on wood, steel screws work best. However, screws used for working with metal are often made of alloys so they are stronger.
When you are making a project that requires metric screws, it can be more difficult to find the screws you need. However, you should be able to find them online, such as at Fastener-Express.com. When you choose the metric screws for your project, it is important to pay attention to the head types, driver types and materials with which you are working to ensure you pick the one that works best for you.
