Wrench set GEKO T00652 — combination wrenches 17-piece 8–32 mm Cr-V CS satin finish

GEKO T00652 is a 17-piece combination wrench set designed for metric fasteners from 8 to 32 mm. The set combines open-end and box-end heads on each wrench to provide access in confined spaces and secure engagement on hex fasteners. Manufactured from chrome-vanadium (Cr-V) steel with a corrosion-resistant CS treatment and satin finish, the tools are intended for workshop, automotive and general maintenance tasks and are supplied as a portable kit suitable for a toolbox.

Advantages

The wrenches are made of chrome-vanadium steel, offering a balance of strength and toughness for repeated use. CS surface treatment with a satin finish increases corrosion resistance and reduces glare while preserving dimensional accuracy. Each combination wrench integrates an open-end for quick turning and a boxed ring end for higher torque and safer contact with fasteners. The set covers a wide metric range from 8 mm to 32 mm, reducing the need to source individual sizes for routine mechanical and maintenance jobs.

Suitable for

• Automotive repair and component maintenance
• General mechanical assembly and disassembly
• Workshop and garage toolkits
• Plumbing and installation work where metric fasteners are used
• Field service and mobile toolboxes

How to use

Select the wrench matching the fastener size and fit the box-end over the nut or bolt for maximum contact and torque. Use the open-end for quick turning where the box-end cannot access or where slight rotation is required. Apply steady, controlled force and avoid sudden impacts or use as a hammer. Store the set in its roll or tray to keep sizes organised and to prevent damage to wrench edges.

Usage recommendations

Inspect tools before use and keep them clean and lightly oiled to maintain the CS-treated satin finish. For high-torque or corroded fasteners consider using the box-end and apply penetrating lubricant to reduce the risk of rounding. Do not use wrenches on damaged fasteners; replace rounded or chipped tools to maintain safe operation.
