Open End Wrench Wera 05020260001

The Wera 05020260001 open end wrench is a high-performance tool designed for precision and reliability in mechanical tasks. Featuring a dual-size configuration of 20 mm and 22 mm, this wrench is engineered to handle hexagonal head bolts and nuts with ease. Its robust construction, utilizing high-performance chrome-molybdenum steel with a nickel-chrome coating, ensures exceptional durability and resistance to corrosion, making it a dependable addition to any professional or home workshop.

Advantages

This wrench stands out due to its innovative jaw design, which incorporates a metal plate that provides a secure holding function, significantly reducing the risk of dropping fasteners. The integrated limit stop prevents the tool from slipping downwards, allowing for the application of higher torque safely. Its double-hex geometry creates a positive connection with the bolt head, minimizing the chance of slipping. Furthermore, the tool features a small return angle of only 30 degrees, which eliminates the need for time-consuming flipping of the wrench in confined spaces.

Suitable for

• Tightening and loosening hexagonal bolts and nuts
• Mechanical assembly and maintenance tasks
• Work in confined spaces where limited movement is available
• Automotive and industrial repair applications

When it may not be suitable

This wrench is specifically designed for metric hexagonal fasteners and may not be suitable for square-headed bolts or non-standard fastener shapes. It is also not intended for use with high-impact power tools or as a substitute for a hammer or pry bar.

Key specifications

• Sizes: 20 mm and 22 mm
• Length: 260.5 mm
• Material: Chrome-molybdenum steel
• Finish: Nickel-chrome coating
• Return angle: 30 degrees
• Holding function: Integrated metal plate in the jaw

How to use

To use the wrench, place the jaw over the bolt or nut head. The integrated metal plate will help hold the fastener in place, preventing it from falling. Apply steady pressure to the handle to turn the fastener. Due to the 30-degree return angle, you can reposition the wrench quickly without removing it entirely from the bolt head, which is particularly useful in tight areas where space is restricted.

What to consider before purchase

• Verify the size of the bolts or nuts you intend to work with to ensure they match the 20 mm and 22 mm specifications.
• Ensure the 260.5 mm length is appropriate for the clearance available in your specific work environment.
• Check if the specific application requires a standard open-end wrench or if a different tool type is necessary for the task.

Usage recommendations

For optimal performance and longevity, keep the wrench clean and store it in a dry environment to maintain the integrity of the nickel-chrome coating. Always ensure the wrench is fully seated on the fastener head before applying force to prevent rounding the edges of the bolt or nut.
