Difference Between T20 And Tx20 | [updated]
T20
In the world of fasteners, the difference between and TX20 is largely a matter of naming conventions rather than physical design. Both refer to the same 6-point star-shaped profile used to drive screws with high torque and minimal slippage. T20 vs. TX20: The Naming Game
3. Tool Life (Wear and Tear)
4. Why This Distinction Matters
- T2: Compatible with most standard Formlabs resins, but struggles with newer, high-performance engineering resins due to the older laser optics.
- TX: Optimized for the full library, including Draft Resin (for fast prototyping) and advanced materials like Tough 2000 and Rigid 10K. The TX optics handle these viscous materials much better.
The Torx drive system was developed in 1967 to prevent "cam-out," a common issue with Phillips and flat-head screws where the driver slips out of the head when high torque is applied. By using a star-shaped design with vertical sidewalls, Torx bits like the T20 provide a broader contact surface for more efficient torque transfer.

Q: Is a T20 the same as a TX20 if I file down the bit?
- Stop forcing the bit.
- Look for a sharp, skinny star (T20) vs a blunt, flat-bottomed star (TX20).
- If the head is shallow and wide, you need a TX20 bit.
- If the head is deep and narrow, you need a T20 bit.
