Combination wrench Gedore R07205005 Height 40 mm Weight 688 g

The Gedore R07205005 combination wrench from gedore red is a hand tool designed for tightening and loosening hex fasteners in mechanical and maintenance work. With a tool height of 40 mm and a mass of 688 g, this wrench balances leverage and compactness for use in workshops, garages, and industrial environments. Constructed to provide a firm grip on nuts and bolts, the combination design integrates an open-end on one side and a boxed (ring) end on the other to accommodate different access conditions.

Advantages

This combination wrench offers a robust construction that supports repeated use under professional conditions. The 40 mm height contributes to improved torque transfer and clearance in confined areas, while the 688 g weight gives a stable feel during operation. The dual-end configuration reduces the need to switch tools when working on fasteners with varying access angles, and the precise machining of the contact surfaces helps minimize rounding of bolt heads.

Suitable for

• Automotive repair and servicing
• Mechanical assembly and disassembly
• Maintenance tasks in workshops and factories
• Plumbing and HVAC installations requiring hex fastener work

Key specifications

• Tool type: combination wrench (open-end and ring end)
• Tool height: 40 mm
• Weight: 688 g
• Material: forged alloy steel with heat treatment (typical for professional wrenches)
• Finish: corrosion-resistant surface treatment for extended service life

How to use

Select the appropriate size of the combination wrench to match the hex fastener. Position the open-end or ring end squarely on the nut or bolt head, ensuring full contact to avoid slipping. Apply steady force to turn the fastener; use the ring end where greater torque is required and the open-end where quick placement or limited access is necessary. Inspect the wrench before use for wear or damage and avoid using cheater bars or extensions that could exceed the tool's intended torque.

Usage recommendations

For safe and effective use, keep contact surfaces clean and free of oil to reduce slippage. Store the wrench in a dry place to prevent corrosion and periodically check for rounding or deformation. Use the appropriate size and avoid excessive impact loads; when higher torque is required, consider using a torque-calibrated tool.
