Open-ended combination wrench Jonnesway W241617 16 x 17 mm

Jonnesway W241617 is an open-ended combination wrench offering two metric sizes—16 mm on one end and 17 mm on the other—in a single compact tool. Made for turning and fastening nuts and bolts, this wrench combines an open end for quick placement and a boxed end for more secure engagement. It is designed for workshop, automotive and mechanical maintenance where a durable hand tool that saves space in a toolbox is required.

Advantages

The combination of open and boxed ends in one steel wrench reduces the need to switch tools when working on adjacent fasteners of different sizes. A slim profile allows access in confined spaces while the boxed end provides better torque transfer and reduced rounding of fastener corners. The compact two-size design simplifies tool selection and storage, making it practical for mobile toolkits or bench use.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Workshop general fastening tasks
• Home repair and DIY projects requiring metric sizes

Key specifications

• Wrench type: open-ended combination wrench with boxed end
• Sizes: 16 mm and 17 mm
• Material: hand tool-grade steel (heat-treated for strength)
• Finish: corrosion-resistant surface treatment
• Profile: slim, offset geometry for access in tight spaces

How to use

Select the end matching the fastener size—16 mm or 17 mm—then place the open or boxed end on the nut or bolt. Use the open end for quick placement or when access is limited; use the boxed end to apply higher torque with reduced risk of rounding. Apply steady, controlled force and avoid sudden impacts. Maintain a perpendicular orientation between wrench and fastener to ensure efficient force transfer and to reduce slippage.

Usage recommendations

Inspect the wrench regularly for wear or deformation before use. For stubborn or seized fasteners, apply penetrating lubricant and allow time to work rather than increasing force abruptly. Store the wrench in a dry place to protect the finish and prolong service life. Use appropriate personal protective equipment when working in confined or hazardous environments.
