Hook Wrench Set Topex 35D251, 2 pieces, 9–32 mm

The Topex Hook Wrench Set 35D251 contains two hook wrenches that span a 9–32 mm engagement range. These tools are designed to engage round or hooked fasteners such as retaining rings, collars and circular fittings where a conventional wrench cannot obtain grip. The compact set is intended for maintenance, assembly and repair work in both workshop and field environments and is compatible with recessed or hard-to-access fasteners.

Advantages

The set provides a simple, reliable method for turning and holding circular fasteners without damaging their profiles. Each wrench is shaped for positive contact with hooked or notched surfaces, reducing slippage during torque application. The compact design makes the tools easy to store in a toolbox or transport to a job site, while the two-size coverage minimizes the need to carry multiple individual wrenches.

Suitable for

• Removing and installing retaining rings and collars in machinery
• Accessing recessed circular fittings in automotive and industrial equipment
• Maintenance tasks where standard open-end or box wrenches cannot engage
• Field repairs and on-site assembly where a compact toolset is preferred

Key specifications

• Set composition: 2 hook wrenches
• Engagement range: 9–32 mm
• Material: heat-treated steel (tool-grade)
• Design: hooked ends for engaging round or notched fasteners
• Finish: corrosion-resistant coating for workshop and field use

How to use

Select the hook wrench that best matches the diameter or notch spacing of the fastener. Position the hooked end into the retaining ring or collar so the contact area bears evenly against the fastener surface. Apply steady torque in the required direction while maintaining axial alignment to prevent slipping or damaging the part. For tight or seized fasteners, apply controlled incremental force rather than sudden impacts and inspect the contact surface periodically to ensure secure engagement.

Usage recommendations

Use the correct size hook wrench to avoid deforming soft fasteners and inspect tools regularly for wear. When working on painted or coated components, protect surrounding surfaces to prevent scratches. Store the wrenches in a dry place to maintain the corrosion-resistant finish and prolong tool life.
