Torque screwdriver Wera 454 HF 100mm

The Wera 454 HF 100mm torque screwdriver is a single-torque tool designed for controlled, repeatable fastening in precision applications. With an overall length of 100 mm and a height of 77 mm, the screwdriver provides a compact profile that helps reach confined spaces while maintaining a comfortable grip and precise handling. The tool’s robust construction supports professional use where a consistent torque output and clear tactile feedback are required.

Advantages

The compact dimensions and ergonomic handle design allow steady one-handed operation and improved access to tight assemblies. The single torque setting simplifies operation and reduces the risk of over- or under-tightening when working to a predefined torque requirement. Durable materials and solid build quality contribute to long service life under regular workshop conditions.

Suitable for

• Precision electronics assembly and maintenance
• Small mechanical fastenings in equipment and appliances
• Field service where portability and compact tools are needed
• Applications requiring consistent single-value torque control

Key specifications

• Tool type: single-torque screwdriver
• Overall length: 100 mm
• Height: 77 mm
• Handle: ergonomic design for controlled grip
• Construction: robust for professional workshop use
• Operation: manual torque application with single preset value

How to use

Verify the required torque value for the fastener before use and ensure the screwdriver’s single torque setting matches the specification for the task. Fit the appropriate bit into the bit holder, position the tool square to the fastener head, and apply steady pressure while turning until the torque mechanism triggers. After the release or click indicating the set torque has been reached, stop applying force to avoid over-tightening. Inspect the fastened joint visually and, if necessary, recheck torque with a calibrated measurement device.

Usage recommendations

Store the torque screwdriver in a clean, dry place and avoid dropping or striking the tool to maintain torque accuracy. Periodically check calibration if used in critical assemblies and consider professional recalibration after heavy use or at manufacturer-recommended intervals.
