Wrench set GEKO flat-ring (open-end/box) 6 pcs CR-V satin finish 34–50 mm

GEKO 6-piece flat-ring wrench set contains six satin-finish CR-V steel wrenches in sizes 34, 36, 38, 41, 46 and 50 mm. Each wrench has a flat profile with an open-end on one side and a ring (box) end on the other, allowing work on hexagonal nuts and bolts with limited clearance. The satin finish reduces glare and provides a surface resistant to minor corrosion and marking during handling.

Advantages

The set is made from chrome-vanadium (CR-V) steel to provide strength and wear resistance suitable for repeated mechanical use. The flat-ring design balances access and torque: the open-end enables quick placement on fasteners while the ring end offers fuller contact for torque transmission. A compact selection of large metric sizes covers common heavy-duty and industrial fasteners without requiring individual purchases.

Suitable for

• Automotive and heavy equipment maintenance
• Industrial assembly and repair work
• Mechanical workshops and service bays
• Home workshops handling large metric fasteners

Key specifications

• Material: chrome-vanadium (CR-V) steel
• Finish: satin
• Set composition: 6 wrenches
• Sizes included: 34 mm, 36 mm, 38 mm, 41 mm, 46 mm, 50 mm
• Profile: flat shank with open-end and ring (box) end

How to use

Select the wrench sized to fit the fastener and place the open-end or ring end over the nut or bolt head. Use the open-end for quick placement in tight access areas and the ring end when higher torque or full-sided contact is required. Apply steady force in the intended rotation direction, avoiding sudden impacts that can damage wrench jaws or the fastener. After use, clean off grease or debris and store the wrenches in a dry place to maintain the satin finish and prevent corrosion.

For optimal performance, avoid using the wrenches with adjustable extenders or cheater bars that increase leverage beyond the tool’s design limits. Periodically inspect the ring and open ends for deformation or rounding; replace any wrench that shows significant wear to prevent fastener damage. Keep the set organized by size to speed up selection during maintenance tasks.
