A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread.
Types of Threads

Screw Thread Terminology
Knowing the different screw types and sizes is helpful, but to accurately select the right screw for your project, you’ll likely need to know a little about how screw threads work, as well. So, how do screw threads work? Like the screws themselves, screw threads are designed to meet the needs of specific applications.
Additional Fastener Terminology
Here are a few additional terms related screws and threading that are helpful to know:
What is embroidery thread grade?
Embroidery thread grades range from 30 to 60, and it’s available in a variety of materials for your machine-sewing or hand-sewing projects. Since it’s not twisted like some other types of threads are, it lies flat, making it a good substitute if you run out of your regular thread in the middle of a project.
What is a thread in a computer?
Another type of thread is used in the operation of central processing units (CPUs) in computing. These threads consist of an ID, stack, a set of registers, and a program counter. They contain sequences of instructions, and many applications require multiple threads. This model allows for faster response times and multi-tasking, leading to greater efficiency.
What is metallic thread used for?

Is PT thread the same as BSPT thread?
PT thread type is identical and interchangeable with BSPT thread type. However, since the male PT thread does not have a 30-degree flare, it will not mate with the BSPP female swivel with conical seat. Also, we recommended using thread sealant with PT threads to ensure a leak-free seal.

General purpose thread
General purpose thread is most commonly 100% polyester, which makes it strong, durable, and flexible. It’s the thread you’ll use most frequently in your sewing projects, and the one you’ll want to buy in every color.
Polyester thread
General purpose threads are usually polyester, but polyester takes many forms. This thread is manufactured differently to have a smooth, shiny finish to be used for decorative applications.
Cotton thread
If you’re interested in natural fibers, it can be tempting to choose cotton instead of polyester thread for a sewing project, but cotton is not as strong as polyester, and lighter weights won’t stand up to the stress of wear over time. If your project isn’t going to be under stress, it’s a perfect natural option.
