Wrench combination 9 mm Proline 35349 — 9 mm open/box spanner, chrome-plated steel

Combination wrench 9 mm Proline 35349 is a hand tool made from chrome-plated steel designed for tightening and loosening 9 mm nuts and bolts. One end features a 9 mm open jaw for quick access and turning in tight spots, while the opposite end offers a 9 mm boxed (ring) profile that provides fuller contact with fasteners for reduced slippage. The chrome-plated finish improves corrosion resistance and simplifies cleaning after use.

Advantages

The chrome-plated steel construction delivers a balance of strength and corrosion resistance suitable for general-purpose maintenance tasks. The dual-end design combines the speed and accessibility of an open-end wrench with the secure grip of a box-end wrench, allowing efficient torque application. The 9 mm size is compact, enabling work in confined spaces and contributing to easier handling and storage.

Suitable for

• Automotive maintenance and light repairs
• Bicycle assembly and adjustment
• Household repairs and furniture assembly
• General workshop use and routine mechanical tasks

Key specifications

• Tool type: combination wrench with open-end and box-end
• Nominal size: 9 mm
• Material: chrome-plated steel
• Finish: chrome plating for corrosion resistance
• Ends: 9 mm open jaw and 9 mm ring (box) end

How to use

Select the 9 mm combination wrench for fasteners with 9 mm flats. Use the open-end side for quick placement on nuts or bolts when access is limited or when turning in short strokes. Use the box-end side to engage the fastener fully when higher torque or reduced risk of rounding is required. Apply steady, controlled force and ensure the wrench is properly seated on the fastener before applying torque. Inspect the tool periodically for wear or damage and avoid using it with extension pipes or in impact applications not intended for hand wrenches.

Usage recommendations

Store the wrench in a dry place to preserve the chrome finish, clean after exposure to corrosive substances, and select the box-end for high-torque operations to reduce fastener damage. For safety, wear gloves and eye protection when performing mechanical work.
