Spanner combination 22 mm Dedra 1456 — 22mm open-end and ring wrench

Dedra combination spanner 22 mm model 1456 combines an open-end and a ring (box) end in a single hand tool designed for working with nuts and bolts measuring 22 mm across flats. The tool is engineered for general mechanical use in automotive, household and workshop environments where a reliable, compact wrench is needed for tightening and loosening fasteners. Solid construction provides consistent torque transfer and a practical balance between access and grip.

Advantages

The combination of an open-end and a ring end allows fast access to fasteners in confined spaces while offering a secure contact with the box end for higher torque operations. A 22 mm size covers a common range of metric fasteners used in vehicles, machinery and domestic fittings. The one-piece design reduces play between ends and improves durability under normal mechanical loads.

Suitable for

• Automotive maintenance and repair tasks requiring 22 mm wrenches
• Workshop assembly or disassembly of machinery with 22 mm fasteners
• Household repairs such as plumbing and furniture tightening using 22 mm nuts or bolts
• Field service and mobile tool kits where a compact, dual-ended wrench is useful

Key specifications

• Tool type: combination spanner (open-end + ring end)
• Nominal size: 22 mm across flats
• Material: forged steel construction for strength and torque transfer
• Finish: corrosion-resistant surface treatment for workshop and household use
• Ends: one open-end for quick placement, one ring end for secure engagement
• Length: compact format for access in confined spaces (typical combination-spanner length for 22 mm size)

How to use

Place the open-end or the ring end around the 22 mm nut or bolt so that the flats of the fastener seat fully within the wrench jaws. Use the open-end for initial quick turning where clearance is limited, and switch to the ring end when a firmer, six- or twelve-point engagement is required to apply higher torque without rounding the fastener. Apply steady force, keeping the wrench flush with the fastener to avoid slippage. Inspect the tool before use for visible damage or excessive wear.

Usage recommendations

For best results, use the ring end for final tightening and heavy loosening to minimize fastener rounding. Do not use the spanner with extensions or cheater bars that exceed recommended manual force, and avoid using the open-end at extreme angles which can increase the risk of slippage. Store the wrench in a dry toolbox and clean after use to maintain the corrosion-resistant finish and ensure long service life.
