The Effects of Thread Angle on Screw Strength

June 4, 2018

When you first look at a toolbox filled with fasteners, your instinct might be to argue that they are all very similar. While it is true that all fasteners possess similar traits, in that they fasten one object to another, they all can operate in different fashions. What do we mean by this? Well, fasteners come in every size, shape, and material that you can think of. Despite the massive amount of differences that we just listed, the most important difference is the type of thread on the fastener. As you'll soon find out, your thread and thread angle can directly impact the strength of your screws!

Impact of Thread Angle on Screw Strength

The ideal screw will tightly secure one piece of material to another. You don't want to screw a compartment into place only for it to fall off as soon as you begin operating the machine, right? Well, in order to make sure that you get the most secured fit, you are going to need to pay attention to the thread angle of your fastener. The thread angle of your screw details the angle of the thread between your flanks, contained by your thread axis. The thread angle defines the shape and utilization of your screw. The screw's thread angle will directly impact the strength of the fastener in a few different ways.

1) Thread Engagement Length - The first way that strength will be measured based on the thread angle of the fastener is the length. The longer the thread engagement is, the stronger the fastener will actually be. Long fasteners that feature finely thread ends will be stronger than their more coarse alternatives.

2) Thread Material Build - Screws come in a variety of different materials. You can purchase screws that are made out of steel, brass titanium, bronze, and even wood! Obviously, the material that you use to make your screw will have a direct impact on the screw's strength, itself.

3) Over Fastening - Finally, if you over-fasten your screw, you will directly inhibit the strength of the fastener. As it turns out, over-fastening your screw is one of the quickest ways to cause problems with your fastener.

Reference our outline above so that you can understand the impact of threading and thread angle on the strength of your screws. If you want to get the right fasteners for your next project, you've come to the proper place. Ordering fasteners that hold their grip is of the utmost importance.
