Wrench (flat) Proxxon PR23834 — 10 x 11 mm

Flat/open-end wrench Proxxon PR23834 — 10 x 11 mm is a compact hand tool designed for manual tightening and loosening of hexagonal nuts and bolts. The dual-size jaws provide access in confined spaces where a single compact wrench is preferred. The tool is suitable for workshop use, automotive repair tasks and general household maintenance and assembly jobs that require a reliable two-size spanner.

Advantages

The slim flat profile allows access to fasteners in narrow gaps and recessed positions while the open-end jaws for 10 mm and 11 mm sizes eliminate the need to switch tools frequently. Solid construction provides stable torque transfer and a consistent fit on hex heads, reducing the risk of rounding. The small footprint makes the wrench easy to store in a toolbox or carry in a pocket during service and repair tasks.

Suitable for

• Workshop maintenance and mechanical adjustments
• Automotive repairs where 10 mm and 11 mm fasteners are common
• Household DIY tasks and furniture assembly
• Equipment servicing in tight or recessed locations

Key specifications

• Open-end sizes: 10 mm and 11 mm
• Flat/open-end wrench design for confined-space access
• Hand-operated tool for manual torque application
• Compact and lightweight profile for portability
• Durable metal construction for repeated use

How to use

Select the appropriate jaw that matches the hexagonal nut or bolt head (10 mm or 11 mm). Place the open end fully onto the fastener to ensure a snug fit, then apply steady manual force in the required direction to tighten or loosen. When working in narrow spaces, orient the flat profile to maximize leverage while avoiding slipping; reposition the wrench as needed to complete rotations when clearance is limited.

Usage recommendations

Inspect the wrench for visible wear or deformation before use. Use the wrench only on properly sized fasteners to minimize damage to the tool and fastener heads. For higher torque requirements, consider using a longer tool designed for increased leverage or a socket with appropriate drive, as excessive force on a compact open-end wrench can cause slippage or tool damage.
