Wera 400 TX T20 Torx Torque Indicator Screwdriver

The Wera 400 TX T20 Torx Torque Indicator Screwdriver is a fixed-torque screwdriver designed for precise, controlled tightening of TORX® screws. Set to 4.0 Nm, it is ideally suited to applications where consistent torque accuracy is critical and over-tightening must be prevented.

The robust slip clutch mechanism delivers a clearly audible and tactile click when the set torque value is reached, making it impossible to apply additional torque beyond the preset limit. This built-in safeguard is particularly valuable for contractors and technicians working with sensitive fixings or assemblies where torque consistency is essential.

A key practical advantage is the higher loosening torque relative to the tightening torque, meaning no additional tools are required to undo screw connections. The tamper-proof design prevents accidental adjustment of the set value, maintaining accuracy throughout the working day. The T-handle ergonomically fills the hand, with softly rounded recessed grips ensuring comfortable, controlled use during repetitive fastening tasks.

Features and Benefits:
• T-handle design for controlled tightening torque and high loosening torque
• Slip clutch provides audible and tactile signal at set torque — impossible to over-tighten
• Tamper-proof against accidental adjustment of the preset torque value
• Loosening torque exceeds tightening torque — no additional tools needed for removal
• Particularly corrosion-resistant blade for long service life
• Ergonomic recessed grip handle for comfortable, fatigue-reducing use
