There are several types of screws, and each has its own benefits and drawbacks.
Some screws, like thread-cutting screws, have edges designed to cut their own thread and remove the material as it is inserted.
Other screws, like thread-forming screws, displace the material instead of removing it as they are pushed into a material.
What Are Thread Cutting Screws？
Thread-cutting screws are screws with a built-in tap, which allows them to create their own thread as they are driven into a pre-drilled hole.
Uses: Thread Cutting Screws are commonly used in applications where a threaded fastener is needed, but it is not possible or practical to tap the threads beforehand.
Thread-cutting screws are typically made from carbon steel or stainless steel machining, although other materials such as brass or bronze may also be used, these types of metal used will depend on the application and the desired characteristics of the thread-cutting screws.
When selecting thread-cutting screws, it is important to consider the thread size, length, and head style that is appropriate for the application.
The thread size will determine the diameter of the screw and the size of the hole that needs to be drilled.
The length of the thread-cutting screws will determine how deep they can be driven into the material.
The head style will determine how the screw can be driven and removed. Common head-of-thread cutting screw styles include Phillips, slotted, and hex.
These thread-cutting screws are a versatile type of fastener that can be used in various applications. The threads cut into the metal sheet by the screw help grip and hold the screw in place. This prevents the screw from coming loose over time, which can be a problem with traditional screws.
What is Thread Forming Screws?
b>Thread-forming screws are one kind of self-tapping screws that are used to form threads in thin metal sheets. Thread-forming screws have a tapered shank with multiple cutting edges. And thread-forming screws are also known as thread-rolling screws or tap-forming screws.
The tapered shank allows the thread-forming screws to have a tapered shank with multiple cutting edges to cut threads into the metal sheet as it is screwed into place, which helps to grip the metal sheet, preventing the screw from coming loose over time.
Thread-forming screws are available in a variety of sizes and materials. The material used for the thread-forming screws will depend on the application.
For example, stainless steel machining thread-forming screws are often used in food processing applications because they are resistant to corrosion.
When selecting thread-forming screws, it is important to consider the size, length, and head style that is appropriate for the application.
There are many benefits to using thread-forming screws instead of traditional screws or bolts.
The benefit is that thread-forming screws create a stronger connection than traditional screws.
Thread-forming screws are typically used in applications where a strong, permanent connection is required.
They are commonly used to fabricate electronics, computers, and appliances.
Thread-forming screws are also used in automotive applications, such as attaching body panels to a car frame.
If you are looking for a strong, permanent connection, thread-forming screws are a great option.
They are easy to install and create a stronger connection than traditional screws.
Thread Cutting Screws vs Thread Forming Screws – What’s the Difference
Thread Cutting Screws: The screw creates the threads as it is turned, so there is no need for a tap.
Thread Forming Screws: Used to form a thread in existing material. The screw forms the threads as it is turned, so there is no need for a pre-drilled hole.
These screws are used when creating new threads in harder materials like steel or brass.
