In this article, we’ll delve into the world of Torx screws, exploring what they look like, their history, and their uses.
What is a Torx Screw?
A Torx screw, also known as a star screw, is a type of screw that features a unique star-shaped pattern on its head. This pattern is designed to provide a secure drive system, making it difficult for the screw to strip or slip out of the screwdriver. The Torx screw was invented in the 1960s by the Camcar Textron company, and it has since become a widely used fastener in various industries, including construction, automotive, and electronics.
The Anatomy of a Torx Screw
So, what does a Torx screw look like? A Torx screw typically consists of the following components:
- Head: The head of a Torx screw features a star-shaped pattern, which is designed to provide a secure drive system. The pattern consists of a series of radial lines that intersect at the center of the screw head.
- Shaft: The shaft of a Torx screw is the long, cylindrical part that connects the head to the tip of the screw.
- Tip: The tip of a Torx screw is the pointed end that is used to pierce through materials.
Torx Screw Sizes
Torx screws come in a variety of sizes, ranging from small to large. The size of a Torx screw is typically indicated by a number, such as T10 or T25. The number refers to the size of the screw head, with larger numbers indicating larger screw heads.

They are available in a variety of sizes and types, making them suitable for a wide range of applications. By understanding what a Torx screw looks like and how to identify it, you can ensure that you are using the right screw for the job.
What is a Torx screw and how does it differ from other screw types?
A Torx screw is a type of screw that features a star-shaped (torx) drive, which is designed to provide a high level of torque and resistance to cam out. This is in contrast to traditional screw types, such as flathead or Phillips head screws, which can be prone to stripping or cam out when subjected to high torque. The unique design of the Torx screw makes it ideal for applications where high torque is required, such as in the construction of electronic devices or automotive parts.
The Torx screw is also designed to provide a secure drive system, which helps to prevent the screw from coming loose over time. This is particularly important in applications where safety is a concern, such as in the aerospace or medical industries. Additionally, the Torx screw is often used in applications where a high level of precision is required, such as in the assembly of delicate electronic components.
What are the different types of Torx screws available?
There are several different types of Torx screws available, each with its own unique characteristics and applications. The most common types of Torx screws include the Torx drive, Torx plus, and Torx security. The Torx drive is the most common type of Torx screw and is used in a wide range of applications. The Torx plus is a variation of the Torx drive that features a slightly different design, which provides even higher torque and resistance to cam out.
The Torx security screw is a type of Torx screw that features a pin or other security device in the center of the drive. This pin helps to prevent the screw from being removed with a standard Torx driver, providing an additional level of security. Other types of Torx screws include the Torx tamper-resistant screw, which features a unique drive design that makes it difficult to remove with a standard Torx driver, and the Torx precision screw, which is designed for use in applications where a high level of precision is required.
What are the benefits of using Torx screws?
One of the primary benefits of using Torx screws is their high level of torque and resistance to cam out.
