Wiha Nut driver - 7mm

This 7mm nut driver is specifically designed for tightening and loosening 7mm hexagonal nuts and bolts in various applications, from electronics to small machinery.

No specific insulation is mentioned in the product information. For electrical work, always use tools explicitly rated and marked as insulated (e.g., VDE approved) to ensure safety.

The blade length of this Wiha Nut Driver is 125mm, providing good reach into recessed areas.

The total length of the Wiha 7mm Nut Driver is 238mm, which contributes to comfortable handling and leverage.

No, this tool is precisely sized for 7mm hexagonal fasteners. Using it on other sizes can damage both the fastener and the tool.

A magnetic tip feature is not specified for this model. Assume it does not have a magnetic tip for holding nuts.

Store the nut driver in a clean, dry place to prevent rust and protect the blade. A tool rack, box, or drawer is suitable.

Ensure the nut driver is fully seated onto the hexagonal nut. Verify the nut is not rounded or damaged, as this can cause slippage. Clean any oil or debris from both the driver tip and the nut.

Apply steady, firm pressure and rotate. Avoid jerking motions. For extremely tight or rusted nuts, consider applying a penetrating oil and allowing it to soak before attempting again. Do not use excessive force that could damage the tool or the fastener.

Clean the rusted area with fine steel wool or a rust eraser. Apply a thin coat of light machine oil to the blade to protect it from further corrosion. Store the tool in a dry place.
