When it comes to screws and fasteners, having the right tool for the job is crucial. One of the most widely used screwdrivers is the Phillips head, and within this category, the #3 Phillips is a staple in many industries. But what size is a #3 Phillips, exactly? In this article, we’ll delve into the world of screwdriver sizes, exploring the specifications, applications, and nuances of the #3 Phillips.
Understanding Screwdriver Sizes
Screwdriver sizes are typically measured in terms of the diameter of the blade and the type of head it fits. The Phillips head screwdriver, invented by Henry F. Phillips in the 1930s, features a distinctive cross-shaped slot that provides better torque and less cam-out (the tendency of the screwdriver to slip out of the screw head) than traditional flathead screwdrivers.
The Phillips head screwdriver has several sizes, each designated by a number that corresponds to the diameter of the blade. The most common sizes are #1, #2, and #3, with the #2 being the most widely used.
Phillips Head Screwdriver Sizes
| Size | Blade Diameter (mm) | Typical Applications |
| — | — | — |
| #1 | 3.2 | Small electronics, watches, eyeglasses |
| #2 | 5.5 | General-purpose, furniture, construction |
| #3 | 7.2 | Heavy-duty, industrial, automotive |
What Is The Size Of A #3 Phillips?
As mentioned earlier, the #3 Phillips has a blade diameter of 7.2 mm. This larger diameter provides more torque and stability, making it suitable for heavy-duty applications.

Tips For Using A #3 Phillips Screwdriver
When using a #3 Phillips screwdriver, keep the following tips in mind:
- Choose the right screwdriver: Ensure that the screwdriver is the correct size for the screw head. Using a screwdriver that is too small can damage the screw or surrounding material.
- Use the correct angle: Hold the screwdriver at a 90-degree angle to the screw head. This ensures maximum torque and prevents cam-out.
- Apply the correct amount of force: Apply gentle but firm pressure to the screwdriver. Excessive force can damage the screw or surrounding material.
Common Mistakes To Avoid
When using a #3 Phillips screwdriver, avoid the following common mistakes:
- Using a screwdriver that is too small: Using a screwdriver that is too small can damage the screw or surrounding material.
- Applying too much force: Excessive force can damage the screw or surrounding material.
- Not using the correct angle: Holding the screwdriver at an incorrect angle can lead to cam-out and damage to the screw or surrounding material.
In conclusion, understanding the size and specifications of a #3 Phillips screwdriver is crucial for ensuring that the right tool is used for the job. With its larger diameter and heavier-duty construction, the #3 Phillips is an essential tool for industries that require high torque and heavy-duty fastening. By following the tips and avoiding common mistakes, you can ensure that your #3 Phillips screwdriver is used effectively and efficiently.
What Is The Significance Of A Number 3 Phillips Drive In Various Industries?
A number 3 Phillips drive, commonly referred to as a #3 Phillips, is one of the most widely used screw drives in various industries, including construction, electronics, and automotive.
