When it comes to construction, having the right screws for the job is essential. The wrong screw can lead to a weakened structure or even a complete failure of the project.


On the other hand, using the right screw in your construction project can ensure that it is strong and secure. But how do you know what size screws you need?


This blog post will explain how to measure the diameter of a screw using the imperial system.


Systems to Measure a Screw


Imperial System


The imperial system is the most common method of measuring screws in the United States. It uses fractions, such as 1/4 inch or 3/8 inch, to measure diameter and length.


The first number refers to the diameter, and the second indicates how long the screw is. For example, a 5/16-inch screw has a diameter of 5/16 inches and is one inch long.










How to Properly Measure a Screw?


No matter which system of measurement you use, it’s important to measure the screw accurately. To do this, look at the following key points:


- Measure the major diameter as well as the minor diameter of the screw first. This will give you an approximate size of what you need for your project. 

- Once the diameter is established, measure the screw length to ensure you have the right size.


Construction screws have numerous applications so it is vital to know you are using ones with the correct dimensions for your designs. Once you have these measurements, you can choose the right screw for your project.
