When it comes to screws, understanding their sizes is crucial for any project, whether it’s a minor repair or a major construction endeavor. Among the various screw sizes, the #2 screw is one of the most commonly used, yet its dimensions can be somewhat confusing for those not familiar with screw sizing conventions. In this article, we will delve into the world of screw sizes, with a particular focus on the #2 screw, exploring its dimensions, applications, and the factors that influence its selection for different tasks.
Introduction to Screw Sizing
Screw sizes can be measured in various ways, including diameter, length, and thread count. The size of a screw is typically indicated by a number (e.g., #2, #4, #6, etc.) for smaller screws and by a fraction or decimal for larger ones. The numbering system for smaller screws, like the #2 screw, does not directly correlate to the screw’s diameter but rather is a gauge system where a larger number indicates a larger diameter. This system can be confusing for beginners, as the relationship between the gauge number and the actual diameter is not linear.
Understanding Gauge Systems
The gauge system used for screw sizing is based on the American Wire Gauge (AWG) system, which was originally designed for measuring the thickness of electrical wires. In this system, as the gauge number decreases, the diameter of the wire (or screw) increases. However, for screws, the gauge system has been adapted and standardized to provide a consistent method of measuring screw sizes. The #2 screw, for instance, has a specific diameter that is larger than a #1 screw but smaller than a #3 screw.
Diameter of a #2 Screw
The diameter of a #2 screw is approximately 0.086 inches or 2.184 mm. This measurement refers to the major diameter of the screw thread, which is the diameter of the thread at its widest point. The minor diameter, which is the diameter at the bottom of the thread, is slightly smaller. Understanding these dimensions is crucial for selecting the right screw for a particular application, as the fit between the screw and the material it is being screwed into must be precise to ensure a secure hold.
Applications of #2 Screws
2 screws are versatile and find applications in various industries, including construction, furniture making, and electronics.

Material Considerations
The material into which the screw is being driven is a critical factor in selecting the appropriate screw size. Different materials have different densities and properties that affect how well they can hold a screw. For example, screws driven into wood are subject to the wood’s grain direction and density, while screws used in metal must consider the metal’s thickness and type. The #2 screw’s diameter and thread pattern make it suitable for a variety of materials, but the specific application will dictate whether it is the best choice.
Thread Patterns and Types
Screws, including #2 screws, come in various thread patterns and types, each designed for specific applications. The most common types include coarse thread and fine thread. Coarse threads are used for thicker materials and provide a quicker assembly, while fine threads are used for thinner materials and offer greater strength. The choice between these types depends on the project’s requirements and the material being used. Additionally, screws can be classified into different head types (e.g., flat head, round head, pan head) and drive types (e.g., Phillips, flathead, hex), which are selected based on the desired appearance, the tool available, and the amount of torque needed.
