Open‑ended and box wrench MODECO 17 mm MN-51-617

Combination wrench MODECO 17 mm MN-51-617 is a hand tool with an open-end jaw at one side and a boxed ring at the other, designed for working with hex fasteners measuring 17 mm across flats. The tool is intended for manual tightening and loosening of nuts and bolts in mechanical, automotive and household maintenance tasks where a medium-sized wrench provides appropriate access and torque.

Advantages

The combination of an open (flat) jaw and a boxed (ring) end offers versatility: the open end allows quick engagement on fasteners in confined positions while the boxed end provides full contact for higher torque and reduced rounding. The 17 mm size covers a common range of metric fasteners used on bicycles, cars, plumbing fixtures and general machinery. The single-piece construction ensures alignment between ends, and the compact length improves access in tighter spaces compared with longer levers.

Suitable for

• Automotive repairs such as wheel, engine accessory and brake component adjustments
• Mechanical assembly and maintenance of small machinery and equipment
• Household repairs including plumbing fixtures, furniture assembly and appliance maintenance
• Bicycle and motorcycle maintenance where 17 mm fasteners are present

Key specifications

• Wrench type: combination (open end and boxed ring)
• Working size: 17 mm across flats
• Material: forged steel construction suitable for manual hand use
• Finish: corrosion-resistant surface treatment for durability
• Ends: one open (flat) jaw and one closed (ring) jaw for full contact
• Intended use: manual tightening and loosening of hexagonal nuts and bolts

How to use

Select the 17 mm end that best fits the fastener and position the wrench so the jaws fully engage the flats of the nut or bolt. For quick positioning or working in narrow gaps, use the open end; for higher torque and to reduce the chance of rounding the fastener, use the boxed end. Apply steady, controlled force and avoid sudden impacts. When loosening, turn counterclockwise; when tightening, turn clockwise. Inspect the tool and fastener before use and replace the wrench if deformation or excessive wear is present.

Usage recommendations

Use the boxed end for final tightening and whenever greater torque is needed. Do not use the wrench as a hammer or lever beyond its intended manual torque limits. Combine with appropriate safety measures such as gloves and eye protection when working on automotive or mechanical systems.
