Open-ended offset wrench Dedra 18 x 19 mm model 1429

Open-ended offset wrench Dedra 18 x 19 mm model 1429 is a hand tool designed with two different open ends—18 mm and 19 mm—and an offset head to provide better access to fasteners located in confined or recessed areas. The wrench delivers manual leverage and a stable grip for tightening and loosening nuts and bolts in automotive, mechanical and household repair tasks. Its compact profile and angled head help reduce knuckle interference and improve reach around obstructions.

Advantages

The Dedra offset open-ended wrench combines two common metric sizes in one durable tool, reducing the need to switch between separate wrenches. The angled head improves accessibility in tight spaces and allows work on fasteners positioned at awkward angles. Solid construction offers reliable manual torque transfer and a precise fit to minimize rounding of nut and bolt corners. The ergonomic handle geometry supports controlled force application during repetitive tasks.

Suitable for

• Automotive repair and maintenance where space around fasteners is limited
• Mechanical assembly and disassembly of machinery and equipment
• Household repairs such as plumbing fixtures, furniture assembly and appliance maintenance
• General workshop use for tightening and loosening 18 mm and 19 mm fasteners

Key specifications

• Open-end sizes: 18 mm and 19 mm
• Offset/angled head for improved access
• Hand-operated lever tool for manual torque
• Material: hardened metal construction for durability
• Finish: corrosion-resistant surface treatment
• Compact length suitable for confined spaces

How to use

Select the end that matches the fastener size (18 mm or 19 mm) and position the open jaws squarely over the nut or bolt head. Apply steady manual force to turn the wrench, ensuring the open end fully engages the flats of the fastener to reduce slipping. Use the offset head to approach fasteners from an angle when direct access is blocked; reposition the wrench as needed to work around obstructions. Avoid using cheater bars or excessive force beyond hand leverage to prevent tool or fastener damage.

Usage recommendations

For safe and effective operation, keep the wrench clean and free of oil buildup to maintain grip and prevent slippage. Inspect the open ends periodically for wear or rounding and replace the tool if fit becomes loose. Use the correct end for each fastener size and apply controlled hand force; for high-torque requirements, consider an appropriately rated socket or torque tool.
