Open-End/Box Wrench Unior 26 mm model U600377, chrome-plated steel, single-piece

Unior Open-End/Box Wrench 26 mm (model U600377) is a single-piece chrome-plated steel wrench designed for reliable torque transfer on hex fasteners. The tool combines an open-end and a boxed end in one unit, each sized for 26 mm nuts and bolts, and features a polished chrome finish to resist corrosion and allow easy cleaning after use. Its one-piece construction provides stable force application for automotive, mechanical and general maintenance tasks that require accurate tightening or loosening.

Advantages

The single-piece design ensures stable alignment between the open and boxed ends, reducing flex and improving torque transfer. Chrome-plated steel offers a balance of strength and surface protection, while the smooth finish helps prevent dirt accumulation and simplifies maintenance. The 26 mm size fits common hex fasteners used on vehicles, machinery and industrial equipment.

Suitable for

• Automotive repairs and maintenance (engine components, chassis fasteners)
• Mechanical and workshop work on machines and assemblies
• Industrial and facility maintenance where 26 mm fasteners are present
• General household and DIY tasks involving medium to large bolts and nuts

When it may not be suitable

This wrench is intended for 26 mm hex fasteners and will not fit other sizes; using it on incorrectly sized fasteners can cause rounding or damage. It is a single fixed-size tool and does not replace adjustable or socket sets needed for a range of sizes or recessed fasteners.

Key specifications

• Tool type: Combined open-end and boxed end wrench
• Size: 26 mm (both open and boxed ends)
• Construction: Single-piece design
• Material: Chrome-plated steel
• Finish: Polished chrome for corrosion resistance and easy cleaning
• Typical use: Manual hand tool for tightening and loosening hex fasteners

How to use

Select the 26 mm wrench end appropriate for the task: use the boxed end for higher torque and confined clearance where full contact with all six sides is required, and use the open end for quicker placement on fasteners or when lateral access is needed. Position the wrench squarely on the fastener to avoid slipping, apply steady force and avoid sudden jerks. After use, wipe the tool clean and store in a dry place to preserve the chrome finish.

What to consider before purchase

• Confirm that the fasteners to be worked on are 26 mm in size.
• Decide if a fixed single-size wrench meets your needs or if a set or adjustable tool is more appropriate.
• Consider work environment requirements for corrosion resistance and ease of cleaning.

Usage recommendations

Use the boxed end for the most secure grip when applying high torque and the open end when access or quick engagement is required. Do not use the wrench as a hammer or pry bar; avoid using cheater pipes or extensions unless the tool is rated for such use, as excessive leverage can deform the wrench and damage fasteners.
