Hand wrench set GEKO T00655 — 15-piece combination wrenches 6–27 mm, CRV steel, satin finish

GEKO T00655 is a 15-piece combination wrench set covering metric sizes from 6 mm to 27 mm. Each wrench combines an open-end and a ring (box) end, manufactured from chrome vanadium (CRV) steel with a satin finish for balanced corrosion resistance and reduced glare. The set is intended for general mechanical, automotive and household repair tasks where reliable metric wrenches are required.

Advantages

The wrenches are made of chrome vanadium steel, providing a solid combination of strength and wear resistance suitable for repeated use. The satin finish limits surface reflections and helps hide minor scratches while offering basic protection against rust. The combination of open and ring ends on every wrench gives versatility for both quick turning and secure torque application. A complete range from 6 mm to 27 mm ensures compatibility with common metric fasteners used in vehicles, machinery and home equipment.

How to use

Select the wrench with the matching metric size and position the open or ring end on the fastener as required. Use the open end for quick repositioning and the ring end for higher torque and reduced rounding of fastener heads. Apply force smoothly and avoid sudden impacts; when higher torque is necessary, ensure the wrench is fully seated on the fastener and use the ring end where possible. After use, clean off dirt and grease and store the set in a toolbox or dedicated rack to keep sizes organized.

Usage recommendations

For safe and long-lasting performance, inspect wrenches regularly for wear or deformation, avoid using them as hammers or prying tools, and pair with appropriate torque control practices. Use protective gloves if working with oily or hot components and store the set in a dry place to preserve the satin finish and steel quality.
