Why the difference? The TX20 design eliminates the "stress risers" (sharp internal radii) found in standard Torx. The load is distributed evenly across a flat surface rather than a pointed tip. , which is the trademarked name for the
It is important to distinguish the standard T20/TX20 from other similar-looking drive systems that are interchangeable: The TX20 design eliminates the "stress risers" (sharp
T20/TX20 screws are highly versatile and widely used across several manufacturing and construction sectors due to their excellent resistance to cam-out (slipping out of the screw head).
While the terms are interchangeable regarding fit, you may encounter slight variations in how they are marketed: : Generally used to denote the standard Torx size.
