Manual screwdriver Wera 05074772001 Single Straight screwdriver, width 37 mm, length 155 mm

Wera torque screwdriver with adjustable torque range and a precision setting mechanism. The tool allows simple, tool-free adjustment of the desired torque value, with an easy-to-read scale and an audible click to signal when the set torque is reached. The Rapidaptor quick-release system enables rapid bit changes, and the driver offers an unlimited torque override for loosening seized screws. The multi-component Kraftform handle combines hard and soft zones for comfortable, high-speed operation. Designed for use with 1/4" hex bits according to DIN ISO 1173-C 6.3 / E 6.3.

Advantages

The screwdriver provides precise and repeatable torque application thanks to its adjustable setting and audible click indicator. Rapidaptor quick-release technology speeds up bit changes, while the unlimited override function permits additional force when freeing stuck fasteners. The ergonomic multi-component handle reduces hand fatigue during frequent or prolonged use and supports efficient turning at higher speeds.

Suitable for

• Controlled tightening of small fasteners in electronics and electrical assemblies
• Maintenance tasks requiring low torque values such as instrument adjustment
• Assembly work where quick bit changes improve workflow

When it may not be suitable

This torque screwdriver is intended for low-torque applications and precision fastening. It is not suited for heavy-duty bolting or applications requiring high torque beyond its adjustable range. For high-torque industrial fastening, a larger torque wrench or powered tool should be used.

Key specifications

• Torque range: adjustable (precision low-torque setting)
• Drive type: 1/4" hex bit interface (DIN ISO 1173 compatible)
• Handle: multi-component Kraftform with hard and soft zones
• Quick-change: Rapidaptor quick-release bit holder
• Size: compact straight screwdriver suitable for small fasteners
• Origin: Czech Republic

How to use

Select a compatible 1/4" hex bit and insert it into the Rapidaptor holder. Set the desired torque value using the adjustment mechanism and confirm the setting by checking the scale. Tighten the fastener until the audible click indicates the preset torque has been reached. If a screw is seized, the unlimited override feature permits additional manual force to loosen it; use caution to avoid over-torquing fragile components.

What to consider before purchase

• Required torque range for your tasks — ensure the screwdriver covers the low-torque values you need
• Compatibility with 1/4" hex bits and common bit types used in your work
• Ergonomics and handedness — the multi-component handle suits frequent use but confirm comfort for your grip

Usage recommendations

Use the audible click as the primary indicator of correct torque application and verify settings visually on the scale before beginning work. For repeated precision tasks, routinely check calibration and avoid using the screwdriver as a pry tool or for applications beyond its torque range.
