Advantages

The wiha Werkstatt 00157 offers a clearly defined 12 mm blade width that improves engagement with matching fasteners and reduces slipping. Its manual design allows for sensitive torque control compared with powered tools, making it suitable for delicate adjustment and maintenance work. The tool is portable and easy to handle in confined spaces when blade reach is sufficient. Compatibility with standard 12 mm applications simplifies tool selection for tasks requiring that blade width.

Suitable for

• Workshop assembly and disassembly of components with 12 mm blade requirements
• Repair and maintenance tasks that require controlled manual torque
• Situations where powered tools are inappropriate or risk damage
• General-purpose hand tool sets needing a 12 mm blade screwdriver

Key specifications

• Blade width: 12 mm
• Drive type: manual screwdriver
• Intended use: fastening and loosening compatible screws and fasteners

How to use

Select the wiha Werkstatt 00157 when a 12 mm blade width matches the fastener. Position the blade fully into the screw head or fastener engagement point to ensure secure contact. Apply steady manual torque in the required direction to fasten or loosen the fastener; avoid excessive force if alignment is poor. If blade length or access is limited, confirm that the tool reaches the fastener without interference before applying force. Store the screwdriver in a dry place after use to maintain condition.

Usage recommendations

Use the screwdriver only with fasteners that match the 12 mm blade width and check access depth since blade length is not specified. For tight or recessed fasteners, confirm clearance or select a tool with known blade length. Maintain a firm grip and controlled torque to prevent slipping and damage to the fastener or screwdriver.
