Open-end/box wrench 17 mm King Tony FT-75517

King Tony open-end/box wrench 17 mm FT-75517 is a combination hand tool designed for fastening and loosening hexagonal nuts and bolts with a 17 mm head. The tool pairs an open-end jaw on one side with a boxed ring on the other, providing access in tight spaces while allowing higher torque application where needed. Constructed for routine automotive, maintenance and assembly work, this 17 mm wrench balances reach and grip for practical workshop use.

Advantages

The combination design offers quick engagement with the open end and secure grip with the boxed ring, reducing slip and rounding of fasteners. One-piece construction provides consistent alignment between the open and boxed ends. The 17 mm size covers a common range of bolts in automotive and mechanical applications, while the boxed ring delivers improved torque transfer for stubborn fasteners. The compact profile aids access in confined areas without compromising strength.

Suitable for

• Automotive repair and servicing tasks involving 17 mm fasteners
• General maintenance and equipment assembly
• Plumbing and workshop jobs requiring access in constrained spaces
• Routine tightening and loosening of hexagonal nuts and bolts

Key specifications

• Tool type: combination (open-end and boxed ring) wrench
• Working size: 17 mm
• Open-end angle and profile suitable for quick engagement
• Boxed ring for enhanced torque and secure fastener contact
• Material: alloy steel (heat-treated) for durability and wear resistance
• Finish: corrosion-resistant surface treatment
• Length and profile: compact design for access in confined spaces

How to use

Select the 17 mm combination wrench and position the open end or boxed ring over the fastener head. Use the open end when you need to slide the wrench onto a bolt in a narrow clearance or to make quick adjustments. Use the boxed ring when higher torque or a more secure grip is required; ensure the ring fully engages the fastener before applying force. Apply steady, controlled force and avoid sudden impacts to preserve tool geometry. When working in tight areas, reposition the wrench and use incremental turns to prevent slippage.

Usage recommendations

Inspect the tool before use for signs of wear or damage. Use appropriate hand force and, when higher torque is necessary, consider using the boxed end rather than the open end to minimize fastener rounding. Store the wrench in a dry place and maintain the corrosion-resistant finish by cleaning after use. For safety, pair the wrench with appropriate personal protective equipment and follow standard torque guidelines for specific fasteners.
