There’s a lot of factors that go into choosing the right Phillips screwdriver – size, head type, and shaft length, to name a few. But if you’re like most people, the first thing you’re probably thinking is “How do I know what number to get?”

Here’s a quick guide to help you make the right choice:

If you’re working with small screws, go for a #0 or #1 Phillips. For larger screws, you’ll need


There are many different types and sizes of Phillips screwdrivers, so it can be difficult to know which one to use for a particular job. The size of the screwdriver is determined by the width of the blade, which is measured in millimeters. The most common sizes are 2mm, 2.5mm, 3mm, and 4mm.

What is a Phillips Screwdriver?

A Phillips screwdriver is a tool used to remove or insert screws with a Phillips head, which is a cross-shaped recessed sockets in the screw head. The Phillips screwdriver was invented in the early 20th century by John Henry Phillips, for which it is named.

How to Determine the Size of a Phillips Screwdriver?

There are two ways to determine the size of a Phillips screwdriver. The first is by the length of the shaft, and the second is by the width of the tip.

The length of the shaft is usually stamped on the side of the handle, and will be either 6 inches (15cm) or 8 inches (20cm). The width of the tip is less commonly stamped, but can usually be determined by looking at the size of the cross in the center of the tip. The most common sizes are #1, #2, and #3.

Factors to Consider When Choosing a Phillips Screwdriver

The Phillips screwdriver is named after its creator, Henry F. Phillips. It is a common type of screwdriver that is used in a variety of applications, both in the home and in industry. When choosing a Phillips screwdriver, there are several factors to consider, including the size and shape of the tip, the length of the shank, and the overall size of the tool.

The tip of the screwdriver is designed to fit into the head of a Phillips screw. The most common sizes are #0, #1, #2, and #3. The larger the number, the larger the tip. The size of the tip should be chosen based on the size of the screws being driven. It is also important to consider the shape of the tip. Phillips screwdrivers come with either a rounded or pointed tip. The rounded tip is more versatile, while the pointed tip is better suited for driving screws into hard-to-reach places.

The shank is the portion of the screwdriver that extends from the tip to the handle. shorter shanks are better suited for driving screws into softer materials, such as wood, while longer shanks are better for harder materials, such as metal. The overall length of the tool should also be taken into consideration when choosing a Phillips screwdriver; longer tools are better for reaching screws in hard-to-reach places, while shorter tools are more convenient for everyday use.

Tips for Using a Phillips Screwdriver

When using a Phillips screwdriver, it is important to make sure that the tip of the screwdriver is the same size as the Phillips head on the screws. If the tip is too small, it will slip out of the head and damage the screw. If the tip is too large, it will strip the head of the screw.

To avoid these problems, it is best to use a size 0 or 1 Phillips screwdriver for screws with a diameter of 3mm or less. For screws with a diameter of 4mm or more, use a size 2 or 3 Phillips screwdriver.

How to Care for Your Phillips Screwdriver

If you own a Phillips screwdriver, it’s important to care for it properly to ensure that it lasts for years to come. Here are a few tips:

-Store your screwdriver in a dry, well-ventilated place.
-Avoid exposing your screwdriver to extreme temperatures.
-If your screwdriver gets wet, dry it off immediately with a clean cloth.
-Do not use your screwdriver as a pry bar or hammer.
– Periodically check the tip of your screwdriver for wear and tear, and replace it if necessary.


There is no need to get confused about which Phillips screwdriver to buy — just remember that the larger the number, the larger the tip. A #1 Phillips is a smaller tip, while a #2 Phillips is a larger tip. If you’re not sure which size you need, err on the side of buying a larger one — you can always use a smaller screwdriver on a large screw, but you can’t use a large screwdriver on a small screw.
