Ring Spanner Bent 6 x 7 mm Dedra 1420

The Dedra 1420 bent ring spanner in size 6 x 7 mm is a compact hand tool intended for engaging hex-headed fasteners in restricted or awkward spaces. Its double-ended ring design with an offset/bent head improves access to bolts and nuts that are difficult to reach with straight wrenches. The tool is manufactured from a durable alloy with a precisely formed ring profile to provide a secure fit on fastener heads and to minimize rounding or slippage during use.

Advantages

The bent head geometry increases clearance and allows improved leverage when working in confined areas. Double-ended rings provide two commonly used metric sizes in one compact tool, reducing the number of separate wrenches required. The alloy construction combines strength with resistance to deformation, while the accurate ring profile ensures consistent engagement with hex fasteners to reduce wear on both tool and fastener.

Suitable for

• Automotive and mechanical maintenance in tight engine bays
• Plumbing work where access behind fixtures is limited
• Assembly and installation tasks in furniture or machinery with recessed bolts
• Electrical enclosure and panel work requiring precise, compact tools

Key specifications

• Sizes: 6 mm and 7 mm (double-ended)
• Type: bent/offset ring spanner (double-ended)
• Profile: closed ring head for hex fasteners
• Material: durable alloy steel construction
• Finish: machined/form-finished ring profile for precise fit
• Overall form: compact, offset design for improved access and leverage

How to use

Select the appropriate end (6 mm or 7 mm) that fits the fastener. Place the closed ring fully over the hex head to ensure full contact with the nut or bolt, then apply steady turning force. Use the bent head to reach fasteners located behind obstructions or recessed in assemblies; the offset angle allows clearance for adjacent components. Take care to align the ring squarely with the fastener to avoid slipping and to reduce the risk of rounding the fastener edges.

Usage recommendations

Inspect the ring spanner for visible wear or damage before each use. Do not use the tool with a hammer or as a pry bar. For high-torque applications, use an appropriately sized spanner or torque tool to avoid overstressing the ring spanner or the fastener.
