Screws are great for holding materials together, but they can also cause problems if the wrong type is used. It’s important to know about the different types of screws, their purposes and uses, as well as how they are sized. In this article, we will cover 13 different screw types, their sizes and how to measure them. Then, you can get the right screws for your next project.
Fasteners are sized according to their diameter, number of threads per inch (if they will be used with a nut or in a threaded hole) and length in inches. This measurement is given as a one or two digit number for smaller screw sizes and fractions for larger ones. The first number is the diameter, and the second is the thread count.
When measuring a screw, make sure it is not stripped or damaged. You can use a tape measure or ruler to determine the size of a screw, but for more precise measurements, a screw gauge is preferred. You can find these in most tool kits or online. Simply place the screw against the gauge and read the numbers to get the size of the screw.
