Open End Wrench Wera 05020262001

The Wera 05020262001 open-end wrench is a metric double open-end spanner designed for hexagonal head bolts and nuts. Made from chrome-molybdenum steel with a nickel-chrome coating, it offers corrosion resistance and durable performance. This single-piece wrench has two sizes (24 mm and 27 mm) and a length of 280 mm to provide good leverage for professional and DIY use.

Advantages

The wrench features a holding function with a replaceable metal plate in the jaw that secures nuts and bolts using hardened teeth, reducing the risk of dropping and slipping. An integrated limit stop prevents downward slipping around the bolt head and allows higher torque to be applied. Double-hex geometry ensures a positive connection with fasteners while the 30° return angle minimises the need to flip the wrench during tightening. The specially forged geometry delivers high torque transfer and strength. Colour-coded Tool Finder marking simplifies size identification.

Suitable for

• Tightening and loosening hexagonal nuts and bolts in automotive repair
• Workshop and industrial maintenance tasks
• Home DIY projects requiring 24 mm or 27 mm spanners
• Applications needing reliable torque transfer and reduced slippage

How to use

Select the appropriate end (24 mm or 27 mm) and position the wrench over the hexagonal fastener so the double-hex geometry seats fully on the nut or bolt. Apply steady force using the handle, taking advantage of the 280 mm length for leverage. Use the holding plate in the jaw when installing or removing loose nuts to reduce the risk of dropping; the integrated limit stop helps prevent slipping down the bolt head. Work with short strokes when space is limited, using the 30° return angle to re-engage the fastener without frequent flipping of the tool.

Usage recommendations

Inspect the replaceable metal plate periodically for wear and replace it if the teeth are damaged. Do not use the wrench on rounded or heavily damaged fasteners. For maximum tool life, keep the surface clean and dry and avoid exposing the nickel-chrome finish to aggressive chemicals.
