Combination wrench Jonnesway W26117 17 mm, open-end and box-end hand tool

Jonnesway W26117 17 mm combination wrench pairs an angled open-end jaw with a 12-point box end in a single hand tool. It is designed for tightening and loosening 17 mm hex fasteners and provides access in confined spaces where a ratchet may be impractical. The boxed end enables more secure torque application while the open end allows quick placement on nuts and bolts.

Advantages

The single-piece construction offers durability and consistent alignment between ends. The 12-point box end reduces the need for exact repositioning on hex fasteners, while the open end gives fast access for initial turning or when working on adjacent components. Its compact profile helps reach fasteners in tight engine bays, machinery housings, and assembly fixtures. The wrench is suitable for repeated manual use and provides predictable leverage for common repair and maintenance tasks.

Suitable for

• Automotive repair and maintenance
• Mechanical and industrial maintenance
• Assembly and disassembly of machinery and equipment
• On-site service work in confined spaces

Key specifications

• Size: 17 mm
• Type: combination wrench with open-end and 12-point box end
• Material: hardened alloy steel (surface finish may vary)
• Profile: slim/compact head for access in tight spaces
• Hand orientation: standard right/left reversible use depending on access angle

How to use

Place the appropriate end of the wrench over the 17 mm hex fastener. Use the open end for quick placement and initial loosening or tightening when clearance permits. Use the box end to apply greater torque and reduce rounding of fastener corners; align the 12-point box over the fastener and turn with controlled force. When working in restricted areas, position the slim head to engage the fastener and use short, steady strokes to avoid slipping. Inspect the wrench for wear or damage before use and keep hands clear of pinch points.

Usage recommendations

Do not use the wrench with impact tools or as a hammer. Use appropriate hand force to avoid tool or fastener damage; consider using a torque wrench for critical torque specifications. Store in a dry place to prevent corrosion and check the tool regularly for deformation or excessive wear.
