Torx ball head wrench Wiha 32389 T20 x 148 mm, T20 ball-end driver 148 mm

Wiha Torx ball head wrench model 32389 T20 x 148 mm is a precision hand tool designed for secure engagement with Torx fasteners. The tool features a T20 tip and a 148 mm overall length with a ball-end head that allows angled insertion into fasteners. This geometry provides improved access in confined areas and enables turning at slight offsets while maintaining firm contact with the fastener profile.

Advantages

The ball-end design permits work at up to several degrees off-axis without slipping, reducing the need to reposition the tool when access is restricted. The 148 mm length offers extended reach for recessed fasteners while keeping control and torque transfer. Manufactured to meet standard Torx dimensions, the driver gives consistent fit and minimizes cam-out. The compact diameter and hardened tip ensure durability and long service life under repeated use.

Suitable for

• Mechanical assembly of components with Torx T20 fasteners
• Maintenance and repair in confined or recessed spaces
• Electronics and appliance servicing where angled access is required
• Automotive and bicycle adjustments needing precise Torx engagement

Key specifications

• Tip size: Torx T20
• Working end: ball-end (ball head) for angled engagement
• Overall length: 148 mm
• Material: hardened tool steel (torque-resistant tip)
• Finish: corrosion-resistant surface treatment

How to use

Insert the T20 ball-end tip into the Torx fastener, ensuring the ball head seats in the recess. For straight engagement apply axial pressure and rotate the wrench; for angled access align the tool at the required offset and maintain steady pressure to keep the tip engaged. Use controlled torque to avoid over-tightening; for higher torque requirements, use a straight driver or a ratcheting tool designed for the task. After use, clean the tip and store the wrench in a protective rack or case to preserve its geometry.

Usage recommendations

Use the ball-end wrench when access prevents direct, axial alignment with the fastener. For critical torque settings or where maximum torque is required, prefer a straight non-ball driver or a torque-limiting tool to ensure accurate tightening. Regularly inspect the tip for rounding or wear and replace the tool if fit becomes loose to prevent damage to fasteners.
