Torx key long with ball head Wiha 366BE T10 121 mm

Long Torx key Wiha 366BE T10 121 mm is a precision tool designed for accessing recessed or angled Torx fasteners. The tool features a long shaft that reaches deep or hard-to-reach screws and a ball head that permits engagement at offset angles, reducing the need to align the tool perfectly with the fastener. Constructed by Wiha for tasks that require accuracy and reliable fitment, this T10 size is suitable for small to medium Torx screws commonly found in electronics and mechanical assemblies.

Advantages

The long shaft provides extended reach for screws located in narrow or deep cavities while the ball head allows angled entry up to several degrees for improved accessibility. Precision-machined Torx profile ensures secure fit in the fastener, reducing cam-out and wear. The compact T10 tip is compatible with common small Torx fasteners, and the overall length offers better leverage compared with standard short keys.

How to use

Insert the T10 tip into the Torx fastener and ensure the ball head seats in the recess to establish engagement. For angled entry, apply steady pressure while maintaining the shaft at the required offset until the ball head engages with the fastener. Turn the key with controlled force; the longer shaft provides leverage but avoid excessive torque that could damage the screw or tool. Withdraw the key by reversing the rotation once the fastener is loosened or tightened to the required position.

Recommendations

Use the long Torx key for tasks where normal keys cannot reach or where access is at an angle. Inspect the tip before use for wear; replace the tool if the Torx profile is rounded to preserve fastener integrity. Store in a dry place to maintain the corrosion-resistant finish.
