What is a 4 40 Thumb Screw?

Before we dive into the buying guide, let’s first understand what exactly a 4 40 thumb screw is. It is a type of fastener that has a threaded shank and a flat head with ridges for easy gripping with your thumb and fingers. The “4” refers to the diameter of the screw in millimeters, while “40” indicates the number of threads per inch. This makes it a small yet sturdy screw that can be easily tightened or loosened by hand without any additional tools.

Why Choose a 4 40 Thumb Screw?

There are several reasons why I would recommend choosing a 4 40 thumb screw over other types of fasteners:

  • Easy to use: With its ridged head, you can easily grip and turn the screw by hand without needing any tools.

Factors to Consider when Buying a 4 40 Thumb Screw

When it comes to purchasing a 4 40 thumb screw, there are a few important factors to keep in mind to ensure you get the best product for your needs:

Material

The most common materials used for 4 40 thumb screws are stainless steel and zinc-plated steel. Stainless steel is stronger and more resistant to corrosion, making it suitable for outdoor or high-moisture environments. Zinc-plated steel is cheaper but still durable and suitable for indoor use.

Thread Type

Thumb screws come in two main thread types: coarse and fine. Coarse threads have fewer threads per inch, which makes them faster to tighten or loosen but less precise. Fine threads have more threads per inch, providing better grip and precision but take longer to turn.

Length

The length of the screw is an essential factor as it determines how deep the screw will go into the material being fastened. Make sure to measure the thickness of your material and choose a screw that is long enough to secure it without going all the way through.

Where to Buy a 4 40 Thumb Screw?

You can find 4 40 thumb screws at most hardware stores, home improvement stores, or online retailers such as Amazon or McMaster-Carr. Make sure to purchase from a reputable seller and check customer reviews before making a purchase.
