How to use

Select the Proxxon Torx screwdriver TTX 40 for fasteners specified as Torx T40. Insert a retaining pin or wire through the shaft hole when axial retention or pin-locking is required to prevent screw loss or to secure the bit during operation. Engage the Torx T40 bit fully into the screw head and apply steady, controlled torque. Use short, even strokes for tightening or loosening to maintain alignment and avoid damage to the fastener head.

Usage recommendations

Use the tool only on Torx T40 fasteners to ensure correct fit and reduce wear. When working with sensitive components, apply minimal necessary torque and consider using torque-limiting tools where precise torque values are critical. Inspect the bit and handle regularly for wear or deformation and replace the tool if engagement with fasteners becomes unreliable.
