When you are working with screws, whether to fix things or for a specific project, selecting the correct ones is essential. You have to consider the size, length, head type and material you are working with. You also need to know what you will be screwing into so that the screw does not tear the hole in the material or break off. There are several ways to measure a screw, but the most important one is its diameter or gauge. This article will show you how to determine the correct screw size for your needs by using a measuring tape, ruler or caliper.
The simplest way to determine the screw size is by its major diameter, which you can measure by placing a measuring device in the threaded portion of the screw. This will give you the measurement of the major diameter, which is a good indication of the threads’ size. The second most important measurement is the threads’ pitch, which you can measure by counting the number of peaks along a one-inch section of the screw. It’s common for more than one thread count to be available for any given screw diameter size, so the threads’ pitch should always be specified when purchasing a fastener.
In the United States, screws are standardized to the Unified Thread Standard (UTS) in inch sizes. However, many companies still use the old British Whitworth system or SAE threading systems when labeling and cataloging their hardware. metric to standard
