Difference Between T20 And Tx20 ~repack~ May 2026

In the world of fasteners, T20 and TX20 are generally different names for the same size of the standard Torx drive system. They both refer to a 6-pointed star-shaped bit with a point-to-point distance of approximately 3.86mm (0.156 inches).

• T20: Standard materials and finish.
• TX20: Premium materials (metal, reinforced chassis), water/dust resistance, or refined ergonomics.

The Problem with Standard Torx: As torque demands increased (e.g., in brake rotors or structural steel), the standard Torx design began to show weakness. The vertical walls acted like a wedge, creating outward radial forces, which could cause the head to crack or the bit to snap. In the world of fasteners, T20 and TX20
