Combination wrench set GEKO 12-piece 6–22 mm CR-V polished

GEKO 12-piece combination wrench set includes 12 metric sizes from 6 mm to 22 mm, manufactured from chrome-vanadium (CR-V) steel with a polished finish. The set contains open-end and box-end combination wrenches designed to fit common metric fasteners used in automotive, mechanical and household maintenance. Packaged as a complete 12-piece kit, it provides a range of sizes for general tightening and loosening tasks in workshops and repair jobs.

Advantages

The polished chrome-vanadium construction improves corrosion resistance and allows easier cleaning after use. Combination heads provide access in confined spaces with the open-end and secure contact with the box-end to reduce rounding of nuts and bolts. A consistent size range from 6 mm to 22 mm covers most common metric fasteners, reducing the need to switch tools frequently. The set format ensures coordinated storage and quick selection of the required size during work.

How to use

Select the wrench size that matches the fastener head and position the box-end for maximum engagement where space allows; use the open-end when access requires it. Apply steady torque and avoid sudden impacts to reduce the risk of rounding fasteners. For stubborn bolts, back off incrementally and inspect threads before continuing. After use, wipe clean and store the wrenches together to maintain organization and prevent surface corrosion.

Usage recommendations

Use the box-end for higher torque applications to minimize slippage and the open-end for quick adjustments in tight spaces. Regularly inspect the tools for wear and keep them clean and lightly oiled to extend service life. Do not use combination wrenches as hammers or pry bars; select appropriate tools for levering or impact tasks.
