Difference Between T20 And Tx20 [ 2024-2026 ]

At a glance, a T20 and a TX20 bit look identical. They are both size 20 star-style drive systems used heavily in automotive, electronics, and construction manufacturing. However, they belong to entirely different design generations. Using them interchangeably damages your fasteners, ruins your tools, and slows down your project.

Understanding the strengths of each system explains where they are most commonly found.

When the original patents for the Torx drive expired, other manufacturers began producing their own versions of these highly efficient star-shaped screws and bits. Because "Torx" is still a registered trademark, some tool brands chose to use alternative naming conventions to avoid legal issues.
