2. PARTIAL THREAD FASTENERS
Finally, down to the most essential phase of knowledge. Partial thread bolts and screws offer an area below the head that is entirely free of threading. They are called partial thread bolts because of the part that has no threading. This non-thread area of a bolt, also known as the bolt shank or shoulder of the fastener, will vary in length depending on the bolt's application.
Why choose a partial thread bolt? Partial thread bolts are best for resistance and alignment. When you have a project that requires a lot of force to hold an object in place, a partially threaded bolt delivers the strength needed. The non-threaded segment, known as grip length, contains zero weak spots to prevent strain.
3. FULL THREAD FASTENERS
As you might have guessed, fully threaded bolts and screws have no grip length or thread-free portion. The threads run from under the head to the tip.
Why choose a fully threaded bolt? If you’re most interested in grip strength and less interested in alignment and shear strength, a fully threaded bolt is going to be your best option. Once mounted, a full thread bolt spreads pressure along its entire length, with the largest holding pressure placed on the head where it meets the material it fastens to.
4. WHAT’S THE DIFFERENCE BETWEEN THE TWO OPTIONS?
The major difference of fully threaded screws vs. partially threaded screws is that full fasteners have threads that run the whole length of the screw, while partial screws have an unthreaded section below the head, which is the grip length. Then there is partial threading the rest of the way down. Both types of fasteners are ideal for a variety of applications, but it’s crucial to know which fits your project as they grip and distribute weight differently. Variables like the head size, thread pitch and type of thread all affect a fastener’s capabilities.
