Combination wrench set Kraft&Dele 12-piece 6–22 mm (open-end and ring wrenches)

Kraft&Dele 12-piece combination wrench set includes metric sizes from 6 mm to 22 mm, each tool combining an open-end and a ring (box) end to provide versatility for a wide range of fastening tasks. The compact assortment covers the most commonly used metric sizes for repair, assembly and maintenance work in automotive, mechanical and household environments. The combination of open and ring ends allows access to confined spaces while offering secure contact for torque application.

Advantages

Each wrench offers the quick engagement of an open-end for speed and the secure grip of a ring end for higher torque and reduced rounding of fasteners. The uniform design provides clear size markings and a balanced feel for manual use, supporting reliable operation in routine maintenance and repair tasks.

How to use

Select the wrench size that matches the nut or bolt head to ensure a snug fit. Use the open-end for quick placement and turning when there is side access or limited clearance; use the ring end for a more secure engagement when applying higher torque or working on stubborn fasteners. Apply steady, controlled force and position your body to avoid slipping; when extra leverage is needed, use the wrench with appropriate caution to prevent tool or fastener damage. Store the wrenches in a toolbox or on a rack to keep sizes organized and protected from corrosion.

Usage recommendations

Inspect fastener condition before use and choose the ring end for high-torque operations to minimize rounding. Do not use the wrenches as hammers or pry bars. Clean and dry the tools after use and apply light corrosion protection if stored in humid environments to extend service life.
