Wrench, Dedra bent box-end 16 x 17 mm model 1428

Wrench, Dedra bent box-end 16 x 17 mm model 1428 is a compact two-size box-end wrench designed for turning hex fasteners in confined or angled spaces. The tool features offset ends that provide improved access to bolts and nuts where straight wrenches cannot reach, making it suitable for automotive, mechanical and household repair tasks that require a durable and reliable compact wrench.

Advantages

The bent box-end design offers better clearance and leverage in tight locations, reducing the need to reposition the tool frequently. Box-end heads fully surround the fastener flats, minimizing slipping and rounding of bolt edges. A two-size configuration (16 and 17 mm) increases versatility while keeping the tool compact and easy to carry. The sturdy construction ensures resistance to deformation under typical torque loads encountered in maintenance and repair work.

Suitable for

• Automotive maintenance: brake calipers, engine components, and suspension assemblies
• Mechanical and industrial equipment repairs in confined spaces
• Household plumbing and furniture assembly where angled access is required

Key specifications

• Wrench type: bent box-end (offset box wrench)
• Sizes: 16 mm and 17 mm
• Ends: boxed heads designed to fit hexagonal fasteners
• Form factor: compact, two-size fixed wrench
• Intended use: manual turning of hex bolts and nuts in restricted or angled spaces

How to use

Select the end that matches the fastener size (16 mm or 17 mm), position the boxed head fully over the flats of the nut or bolt, and apply steady turning force. Use the offset to access fasteners where a straight wrench cannot reach; when clearance is limited, position the wrench so the offset head aligns with surrounding components. If greater leverage is required, ensure the wrench is seated correctly on the fastener to avoid rounding. After use, store the wrench in a tool roll or toolbox to protect the boxed ends and maintain fit accuracy.

Usage recommendations

For best results, inspect the wrench and fastener for damage before application. Use the wrench only on properly sized fasteners to prevent slipping. Avoid impact tools or excessive force beyond manual leverage limits to preserve the integrity of the boxed ends and ensure safe operation.
