Combination offset box wrench Dedra 14 x 15 mm model 1426

Combination offset box wrench Dedra 14 x 15 mm model 1426 is a compact hand tool with two closed (box) ends sized 14 mm and 15 mm. The offset, or bent, profile raises the working ends above the handle plane, allowing access to nuts and bolts in recessed, tight or obstructed locations while keeping the user's hand clear of nearby surfaces. Constructed for manual torque application, this wrench is intended for tasks that require precise engagement and a reliable grip on hexagonal fasteners.

Advantages

The offset box ends provide improved clearance and reach compared with straight box wrenches, making it easier to work around flanges, brackets and engine components. Having both 14 mm and 15 mm sizes in one tool reduces the need to switch wrenches frequently. The closed-end design delivers full contact with the fastener faces, which helps minimize rounding of bolt heads and improves torque transfer. Its compact length and simple geometry make it suitable for use in portable toolkits and constrained working spaces.

Suitable for

• Automotive maintenance and repair — brake, suspension and engine components where access is restricted.
• Household repairs — plumbing fixtures, furniture assembly and appliance servicing in tight areas.
• Mechanical and industrial maintenance — machinery adjustments and equipment fastening in confined spaces.

Key specifications

• Tool type: combination offset box wrench with two closed ends
• Sizes: 14 mm and 15 mm
• Design: offset/bent ends for increased clearance
• Drive: manual hand tool for direct torque application
• Typical materials: chrome-plated or alloy steel construction for durability and corrosion resistance
• Finish: smooth, polished or plated surface to reduce corrosion and ease cleaning

How to use

Select the end that matches the fastener size (14 mm or 15 mm) and place the closed end fully over the nut or bolt head to ensure maximum contact. Apply steady, controlled force to turn the fastener; use the offset to clear nearby obstructions and allow hand clearance. For stubborn or tightly torqued fasteners, ensure correct hand positioning and, if necessary, use gradual force increments to avoid slipping or rounding the fastener. After use, clean off debris and store the wrench in a dry place to maintain its condition.

Usage recommendations

Use this Dedra offset box wrench for manual tightening and loosening of hex fasteners in confined spaces. Do not use cheater bars or excessive leverage beyond manual force limits to avoid tool deformation or fastener damage. Periodically inspect the wrench for wear or rounded edges and replace if the fit on fasteners becomes poor.
