Flat-ring combination wrench set GEKO G11156, Cr-V polished, sizes 6–36 mm, 25 pieces

GEKO G11156 is a 25-piece set of polished chrome-vanadium flat-ring combination wrenches covering metric sizes from 6 mm to 36 mm. Each wrench features a straight open flat jaw on one end and a ring end on the other, designed to engage hex fasteners securely. The combination of Cr-V steel and a polished finish ensures resistance to corrosion and long-term mechanical stability, making the set suitable for workshop, automotive repair and general maintenance tasks.

Advantages

The wrenches are manufactured from chrome-vanadium steel for enhanced strength and wear resistance, with a polished surface that reduces the risk of rust. The flat open jaw offers quick engagement on nuts and bolts while the ring end provides full contact on hex fasteners for reliable torque transfer. The set includes a wide range of sizes from 6 mm to 36 mm, enabling use across small precision jobs to larger mechanical assemblies. Durable construction and precise sizing help maintain fit and reduce fastener rounding.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Home and workshop general maintenance
• Plumbing and light industrial applications
• Professional service technicians and hobbyists

How to use

Select the wrench matching the fastener size, place the open end or ring end over the nut or bolt, and apply steady force in the required direction. Use the open flat jaw for quick placement and the ring end when higher torque or full contact with the fastener is needed. Ensure the wrench is fully seated on the fastener before applying torque to avoid slippage and rounding. After use, clean off dirt and store the wrenches in a rack or toolbox to keep sizes organized and protect the polished finish.

Usage recommendations

For best results, choose the ring end when applying higher torque and avoid using the wrenches as hammers or pry bars. Regularly inspect for wear and keep the polished surface dry and lightly oiled to maintain corrosion resistance. Match wrench size precisely to fastener size to reduce risk of damage.
