Box-end Offset Wrench Dedra 25 x 28 mm model 1434

Dedra box-end offset wrench model 1434, sizes 25 x 28 mm, is a hand tool with offset closed ends designed to grip hexagonal nuts and bolts. The bent box ends provide clearance for fingers and knuckles when working in recessed or confined areas, allowing torque to be applied where a straight wrench cannot reach. Constructed for routine mechanical, automotive and industrial maintenance tasks, this offset wrench offers two commonly used metric sizes in one tool.

Advantages

The offset geometry reduces interference with surrounding components and improves access to fasteners located in tight spaces. Dual box ends maximize versatility by covering both 25 mm and 28 mm hex fasteners without changing tools. The closed-end design provides a secure contact on the flats of a nut or bolt, enabling controlled torque application and minimizing rounding of corners under load.

Suitable for

• Automotive repairs, including suspension and engine bay fasteners
• Mechanical assembly and maintenance in workshops
• Industrial equipment servicing where recessed nuts are present
• General household repair tasks requiring large metric sizes

Key specifications

• Wrench type: box-end offset (closed-end)
• Sizes: 25 mm and 28 mm
• Offset angle: bent ends for increased clearance (offset design)
• Intended use: torque application on hexagonal nuts and bolts
• Typical applications: automotive, mechanical, industrial maintenance

How to use

Select the correct end (25 mm or 28 mm) that matches the hexagonal fastener. Position the closed end fully over the nut or bolt head so the flats are engaged. Apply steady, controlled force to the handle in the required direction to tighten or loosen the fastener. Use the offset ends to clear nearby obstructions; if additional leverage is needed, apply force gradually to avoid exceeding the fastener or tool capacity.

Usage recommendations

Inspect the wrench before each use for signs of wear or deformation. Use the correct size to reduce the risk of rounding fastener edges. Avoid using cheater bars or excessive impact loads on the wrench; for rusted or seized fasteners consider applying penetrating lubricant and using appropriate impact-rated tools.
