Open-ended combination wrench Jonnesway 8x10 mm, double-size open and box ends

Jonnesway 8x10 mm open-ended combination wrench features an open end and a box end sized for 8 mm and 10 mm fasteners. The compact design provides access in confined spaces while allowing reliable torque transfer for routine maintenance, assembly and repair tasks. This double-size wrench combines two common metric sizes into a single hand tool suitable for automotive, mechanical and household use.

Advantages

The wrench offers two functional ends—an open jaw for quick engagement and a boxed 12-point or 6-point end (depending on model) for secure gripping and reduced slippage. Its compact length improves reach in tight areas and enables better leverage compared to smaller wrenches. Constructed from hardened steel with a corrosion-resistant finish, the tool is intended for repeated use under typical workshop conditions and provides consistent fit on metric fasteners.

Suitable for

• Automotive repair and maintenance
• General mechanical assembly and disassembly
• Household repairs and DIY projects
• Tight-space fastening where multiple wrench sizes would otherwise be needed

Key specifications

• Sizes: 8 mm and 10 mm (open and box ends)
• Type: combination wrench with open end and box end
• Material: hardened steel with protective finish
• Finish: corrosion-resistant treatment
• Length: compact profile for improved access in confined areas

How to use

Select the end that matches the fastener size and place the open or box end fully over the nut or bolt head. For initial quick turning, use the open end; for finishing or applying higher torque use the box end to reduce rounding. Position the wrench squarely on the fastener, apply steady force and avoid sudden impacts. To work in tight spaces, use controlled movements and reposition the wrench as needed to maintain leverage and clearance.

Usage recommendations

Inspect the wrench and the fastener seating before applying high torque; use the box end for tighter fastening and avoid using the wrench as a hammer or pry bar. Store the tool in a dry place and keep it clean to preserve the protective finish and ensure long service life.
