Manual screwdriver Wera 05074840001 Single straight screwdriver, length 105 mm

Wera 05074840001 manual screwdriver Single Straight screwdriver, length 105 mm. This torque screwdriver is designed to provide safe protection against electrostatic charge while delivering a factory pre-set torque value at the lowest scale setting. It maintains a constant torque and repeatable accuracy for tasks that require uniform fastening force and includes Rapidaptor quick-release technology for fast bit changes. The multi-component Kraftform handle combines hard and soft zones to support high working speeds and comfortable handling. Unlimited loosening torque allows freeing stuck screws when needed. The torque can be adjusted with an additional tool within the measuring range and verified using a standard torque tester.

Advantages

Provides ESD protection to prevent electrostatic damage and comes from the factory with a preset lowest torque for immediate use. Offers precise, repeatable torque application for consistent results and features Rapidaptor quick-release for efficient bit swaps. The ergonomic Kraftform handle balances grip and comfort for sustained work. Loosening torque is unlimited, enabling removal of seized fasteners without damaging the torque mechanism.

Suitable for

• Precision assembly and electronics where ESD protection is required
• Applications needing a constant, repeatable torque value
• Maintenance tasks requiring quick bit changes
• Tightening screws in confined spaces due to compact 105 mm length

When it may not be suitable

This tool is preset at the lowest torque scale and may not be suitable where higher factory-set torque is required without adjustment. If you need a different torque range frequently, you will need the additional tool for adjustment or a different torque screwdriver model.

Key specifications

• Overall length: 105 mm
• Drive type: 1/4" hexagon bits (DIN ISO 1173 C 6.3 / E 6.3)
• ESD-safe construction to protect against electrostatic charge
• Factory pre-set to the smallest torque scale value; adjustable within measuring range with an extra tool
• Rapidaptor quick-release bit change system
• Multi-component Kraftform handle with hard and soft zones
• Unlimited loosening torque for removing stuck screws

How to use

Select a compatible 1/4" hex bit and insert it into the Rapidaptor quick-release chuck. Use the screwdriver to apply the preset torque; for a different torque setting, change the torque with the required adjustment tool and then verify the value with a commercial torque tester. For loosening, apply reverse rotation as needed — the unlimited loosening torque permits freeing seized screws without triggering the torque mechanism.

What to consider before purchase

• Preset torque is at the lowest scale value; check whether this meets your application or if you need to plan for adjustment
• Ensure compatibility of 1/4" hex bits per DIN ISO 1173 C/E
• Consider whether you need a torque tester for verification after adjustment

Usage recommendations

For precise electronic assembly and repetitive tightening tasks, use the screwdriver with ESD-safe work practices, verify adjusted torque settings with a torque tester, and keep a set of compatible 1/4" hex bits for efficient operation.
