Socket wrench insert, Wera 8790 B, 10 mm, 3/8" drive, VDE insulated

The Wera 8790 B socket wrench insert is a 10 mm, 3/8" drive VDE insulated insert engineered for safe operation on electrical installations within applicable VDE insulation ratings. Designed to fit compatible 3/8" ratchets and handles, this socket insert provides precise torque transfer and a secure fit while offering electrical protection for work on live or potentially live circuits when used as part of a complete insulated tool system.

Advantages

The insulated design reduces the risk of electrical shock when used correctly and in accordance with the applicable VDE standards. The 10 mm size and 3/8" drive ensure compatibility with a wide range of ratchets and handles, enabling accurate force transmission and stable engagement with fasteners. Constructed to maintain reliable mechanical performance while incorporating insulation, the insert supports safe and efficient electrical assembly and repair tasks.

Suitable for

• Electrical assembly and maintenance on equipment and installations within VDE-rated voltage limits
• Field service and workshop work by electricians and maintenance technicians
• Tightening and loosening 10 mm fasteners where insulated tools are required

Key specifications

• Size: 10 mm socket insert
• Drive type: 3/8" drive
• Insulation: VDE insulated for electrical work (use within applicable VDE ratings)
• Compatibility: Fits standard 3/8" ratchets and handles designed for insulated inserts
• Application: Designed for manual torque transfer to hex fasteners

How to use

Select a compatible 3/8" ratchet or handle and mount the 10 mm socket insert securely. Verify that the complete tool assembly (ratchet/handle plus insert) is undamaged and that the insulation is intact before use. Use the insert to engage and turn 10 mm hex fasteners, applying torque within the safe range for the hand tool and the fastener. After use, inspect the insulation for cracks, cuts or other damage and remove the tool from service if the insulation is compromised.

Usage recommendations

Use this VDE insulated socket insert only as part of a fully insulated tool set and in accordance with current VDE safety standards and workplace rules. Regularly inspect insulation integrity, avoid using the insert on live circuits beyond the specified VDE limits, and replace the insert if any damage is detected.
