Wrench ks tools Maulschlüssel 19+15 mm model 150.9644

Combination wrench ks tools Maulschlüssel 19+15 mm model 150.9644 is a hand tool designed for manual tightening and loosening of metric fasteners. The dual-size design integrates a 19 mm and a 15 mm open/box end in a single compact wrench, providing quick access to two common sizes without changing tools. The tool is intended for use in automotive repair, maintenance and general workshop tasks where space is limited or frequent size changes occur.

Advantages

The compact dual-size configuration reduces the number of individual wrenches required and speeds up workflow when switching between 19 mm and 15 mm fasteners. Constructed from chrome-plated steel, the combination wrench offers corrosion resistance and a smooth surface finish that eases cleaning. The open end provides quick entry on nuts and bolts in confined positions while the box end ensures a secure grip for higher-torque operations. The flat profile and moderate length improve access in tight engine bays and machinery housings.

Suitable for

• Automotive repairs and tire/part removal where 19 mm and 15 mm fasteners are used
• Routine maintenance and servicing in workshops and service garages
• Assembly and disassembly of machinery, equipment and household items
• Field service and mobile repair tasks requiring a compact toolset

Key specifications

• Wrench type: Combination wrench with open and box ends
• Sizes: 19 mm and 15 mm
• Material: chrome-plated alloy steel for durability and corrosion resistance
• Finish: polished/chrome-plated surface
• Profile: flat design for improved access in tight spaces
• Use: manual operation for tightening and loosening fasteners

How to use

Select the correct end (19 mm or 15 mm) that matches the nut or bolt head. Place the open or boxed end squarely onto the fastener to avoid rounding. For initial loosening in confined spaces, use the open end; switch to the box end for final removal or for applying higher torque. Maintain steady pressure and avoid sudden impacts; use with appropriate force by hand to prevent tool or fastener damage. After use, wipe the wrench clean and store in a toolbox or on a wrench rack to prevent corrosion and loss.

Recommendations

Use the box end for higher torque applications and when the fastener is partially rounded; use the open end for quick placement in tight spaces. Do not use the wrench with extensions, cheater bars, or impact tools. Regularly inspect the wrench for wear and replace if the ends become deformed to maintain safe and effective operation.
