Wrench, Dedra 1431 bent ring spanner 20 x 22 mm

Wrench Dedra 1431 bent ring spanner 20 x 22 mm is a hand tool with two closed-ring ends sized 20 mm and 22 mm. The offset or bent profile places the rings away from the handle axis, improving reach and clearance when working in confined, recessed or obstructed locations. Constructed for engagement with hexagonal nuts and bolts, this ring spanner delivers reliable torque transfer for mechanical repairs, installations and routine maintenance where those sizes are required.

Advantages

The bent ring spanner design provides improved access compared with straight ring wrenches, allowing you to work on fasteners that are hard to reach or surrounded by other components. Closed-ring ends ensure positive, wrap-around contact with hexagonal heads for reduced slipping and rounded-corner damage. Dual-size ends (20 mm and 22 mm) eliminate the need to switch tools for adjacent fastener sizes, supporting efficiency in service and installation tasks.

Suitable for

• Automotive repairs and brake or suspension work where space is limited
• Plumbing and heating installations with recessed fittings
• Mechanical assembly and disassembly in workshops
• General maintenance tasks on machinery and equipment

Key specifications

• End sizes: 20 mm and 22 mm
• Bent/offset ring configuration for increased clearance
• Closed-ring (box) ends for full-face engagement with hex fasteners
• Hand tool intended for manual torque application

How to use

Select the appropriate end (20 mm or 22 mm) that matches the hexagonal nut or bolt head. Place the closed ring fully over the fastener head to ensure full contact between the tool and the fastener flats. Apply steady, controlled force to turn the fastener; use the bent profile to reach fasteners in tight or recessed positions while maintaining a comfortable grip on the handle. Avoid using improvised extensions or impact tools unless the spanner is explicitly rated for such use.

Usage recommendations

Inspect the ring ends for wear or deformation before use, and maintain clean contact surfaces to reduce slipping. Use appropriate personal protective equipment when working on pressurized systems or moving machinery. Store the spanner dry and avoid corrosive environments to prolong its service life.
