The difference between multi-point (often called XZN) and Torx is a common topic among car mechanics and DIY enthusiasts. Sometimes the terms are used interchangeably, but there are subtle yet important distinctions that you should know to choose the right tool for the task. 
Comparison of Vielzahn (XZN) and Torx screw heads
Multi-point (XZN) screws have a straight, parallel profile with multiple teeth. These teeth engage with the corresponding recesses in the tool. In contrast, Torx has a star-shaped profile with six rounded lobes. This shape offers higher torque transfer and reduces the risk of cam-out.
What is the Difference Between Multi-point (XZN) and Torx?
The main difference lies in the shape of the drive tips. Torx has six rounded lobes, while multi-point has several straight, parallel teeth. These different profiles affect power transmission and tool durability. Torx Vielzahn Dr. Klaus Müller, author of “Modern Fastening Technology,” explains: “The rounded lobes of the Torx profile distribute force more evenly and minimize the risk of stripping screw heads.”
This characteristic makes Torx particularly suitable for high-torque applications, such as in the automotive industry. Multi-point, on the other hand, is often found in areas where lower torque is sufficient.
Advantages of Torx Over Multi-point (XZN)
Torx offers several advantages over multi-point:
- Higher Torque Transfer: The rounded lobes allow for better power transmission.
- Lower Risk of Cam-out: The shape of the Torx profile minimizes tool cam-out.
- Greater Durability: Due to the even force distribution, tool wear is reduced.

When Should You Use Multi-point (XZN)?
Despite the advantages of Torx, there are situations where multi-point is the better choice. For example, with older vehicles or equipment specifically designed for multi-point fasteners. Inner Square Socket In such cases, using the correct multi-point tool is essential.
