Screwdriver Bit TORX Wera TORX 89 mm TR 20 6.3 mm for 1/4 inch holders

Wera TORX screwdriver bit TR 20 with an overall length of 89 mm and a 6.3 mm (1/4") hex shank is made for tasks that require a secure TORX TR20 engagement. The bit is intended for use with standard 1/4" bit holders, manual bit drivers and power tools that accept 6.3 mm hex shanks. Its extended length helps reach recessed fasteners while maintaining precise fit and controlled torque transfer for assembly, maintenance and repair work.

Advantages

The bit combines a defined TORX profile with a consistent 6.3 mm hex shank for compatibility with a wide range of drivers and holders. Its 89 mm length improves access to deep or recessed screws without compromising handling. The manufactured tip ensures accurate seating in TORX TR20 fasteners to reduce cam‑out and wear during repeated use. The robust shank geometry promotes stable torque transmission from manual and powered drivers.

Key specifications

• Bit type: TORX TR20 profile
• Overall length: 89 mm
• Shank diameter/type: 6.3 mm (1/4") hex shank
• Compatibility: standard 1/4" bit holders, manual and powered drivers accepting 6.3 mm hex
• Application: assembly, maintenance, repair, recessed fasteners

How to use

Insert the 6.3 mm (1/4") hex shank into a compatible bit holder, screwdriver or power driver until it engages securely. Position the TORX TR20 tip into the matching fastener, apply axial pressure to keep the tip seated, and turn the tool at the appropriate speed and torque for the material and fastener size. For powered tools, set torque and speed limits according to the fastener and workpiece to avoid over‑tightening. After use, inspect the tip for wear and store the bit in a suitable holder to protect the profile.

Recommendations

Use the bit with holders and drivers rated for 1/4" hex shanks and select appropriate torque settings for the application. Replace the bit if the TORX profile shows rounding or deformation to maintain secure engagement and prevent damage to fasteners.
