Open-ring wrench MODECO 22 mm model MN-51-622

The MODECO open-ring wrench 22 mm (model MN-51-622) is a combined hand tool with an open jaw on one end and a ring on the other, intended for working with hexagonal nuts and bolts measuring 22 mm across flats. Constructed from durable metal, the wrench provides reliable torque transfer and a secure grip for tightening and loosening fasteners in mechanical, automotive and household repair tasks where a single-size spanner is needed.

Advantages

The combined open-ring design offers versatility by allowing quick access to fasteners with the open jaw and secure, full-contact engagement with the ring end for higher torque applications. The 22 mm jaw size matches common metric fasteners used in automotive and machinery maintenance. Solid metal construction ensures long service life and consistent performance under repeated use. The compact length and flat profile make it easy to work in confined spaces where a single-size tool is required.

Suitable for

• Automotive maintenance and repair tasks involving 22 mm fasteners
• Mechanical and equipment assembly where precise tightening is necessary
• Household repairs and DIY projects using 22 mm nuts and bolts
• Workshop use for routine maintenance on bicycles, small engines and machinery

Key specifications

• Type: combined open-ring wrench (one open end, one ring end)
• Jaw size: 22 mm across flats
• Material: durable metal construction for torque transfer
• Finish: corrosion-resistant surface treatment (factory applied)
• Profile: flat, compact design for access in limited spaces

How to use

Select the 22 mm open-ring wrench when the fastener measures 22 mm across flats. Use the open end for quick placement on exposed bolts or nuts and the ring end for a secure grip when higher torque or full contact is required. Position the wrench so that force is applied squarely to the flats of the fastener to minimize rounding. For loosening, apply controlled force and, if needed, use steady back-and-forth motion to free seized fasteners. After use, wipe clean and store in a dry tool organizer to maintain performance.

Usage recommendations

Use the ring end for final tightening or loosening to reduce the risk of slipping; avoid excessive impact force or using the wrench as a hammer. Inspect the wrench periodically for wear or head deformation, and replace it if the jaws no longer seat squarely on 22 mm fasteners.
