Flat wrench Dedra 21 x 23 mm model 1480P — open-end hand tool

Flat (open-end) wrench Dedra model 1480P combines two common metric sizes — 21 mm and 23 mm — in a slim-profile open-end hand tool. Designed for tightening and loosening hex nuts and bolts of these sizes, the wrench is suitable for general mechanical, automotive and household applications where limited access prevents use of bulkier tools. The flat, open jaw design allows access to fasteners located in narrow spaces and on closely spaced bolt heads.

Advantages

The Dedra flat wrench offers two sizes in one compact tool, reducing the need to carry multiple wrenches. Its open-end profile provides quick engagement with hex heads and allows side access where box or socket wrenches cannot fit. The slim body is intended to reach fasteners in tight clearances and between components, while the hardened steel construction ensures durability under typical torque for 21 mm and 23 mm fasteners. The simple, manual design requires no power source and is easy to store in a toolbox or carry in a tool roll.

Suitable for

• Automotive maintenance and repairs involving 21 mm and 23 mm fasteners
• Mechanical assembly and disassembly tasks in workshops
• Household repairs where slim open-end access is needed
• Field service and mobile tool kits requiring compact hand tools

Key specifications

• Tool type: flat open-end wrench with dual sizes
• Size options: 21 mm and 23 mm open ends
• Profile: slim, flat body for narrow access
• Suitable fastener type: hex nuts and bolts (metric)
• Typical use: manual tightening and loosening of 21 mm and 23 mm fasteners

How to use

Select the open end that matches the hex fastener size (21 mm or 23 mm). Seat the open jaw fully onto the nut or bolt head with the wrench oriented to provide sufficient leverage while avoiding slipping. Apply steady manual force in the required direction to tighten or loosen the fastener. For confined spaces, align the slim body between adjacent components to reach the fastener; reposition the wrench as needed to incrementally turn the fastener. Use appropriate hand positioning and apply controlled force to reduce risk of rounding fastener corners.

Usage recommendations

Use the correct end for the fastener to minimize wear and rounding. Inspect the wrench for signs of wear or damage before use and avoid applying impact forces or using as a hammer. For higher torque requirements, use a suitable larger or boxed wrench or a torque-rated tool instead of excessive force on the flat open-end wrench.
