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.

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.
