Impact Ring Wrench GEKO G16055 55 mm — single-head impact spanner for hammering applications

GEKO G16055 is a 55 mm impact ring wrench engineered for hammering and heavy-duty impact applications. The single-head ring configuration provides a closed engagement around bolt heads and nuts, allowing safe transmission of percussive force from impact hammers or striking tools. Constructed for workshops, garages and industrial maintenance, this tool is intended for tasks where repeated impact blows are used to loosen or tighten fasteners without rounding their profiles.

Advantages

The impact ring wrench offers a fully enclosed ring end that ensures positive contact with the fastener and reduces slippage during hammer strikes. Its solid construction transmits impact energy efficiently to the fastener while protecting the bolt head from direct hammer damage. The 55 mm size gives access to larger nuts and bolts commonly found in automotive, construction and heavy equipment applications. The single-head design makes the tool compact and easy to position in confined spaces.

Suitable for

• Automotive wheel and axle assemblies requiring impact loosening or tightening
• Construction machinery maintenance and assembly tasks
• Industrial and plant maintenance where high-impact torque is applied
• Repair shops and service garages using impact hammers or striking tools

Key specifications

• Wrench type: single-head impact ring wrench
• Working opening: 55 mm
• End style: closed ring for full engagement with fastener
• Intended use: designed for percussive impact and hammering applications
• Typical materials: forged steel or equivalent high-strength alloy (manufacturing grade as supplied by the brand)

How to use

Select the 55 mm impact ring wrench when the fastener size matches the ring opening. Seat the closed ring fully over the nut or bolt head to ensure full contact. Use an impact hammer or a striking tool to deliver controlled blows to the wrench body or striking surface, transmitting percussive force through the ring to the fastener. Maintain a stable stance and secure the workpiece to prevent movement during repeated impacts. After loosening, switch to appropriate torque tools for final tightening to specified torque values where required.

Usage recommendations

Inspect the ring wrench before use for cracks, deformations or excessive wear. Do not use a damaged tool. Wear suitable personal protective equipment such as safety glasses and gloves. Use the wrench only with striking tools intended for impact work and avoid combining it with non-impact-rated handles or extensions. For final torque accuracy, use calibrated torque wrenches rather than impact blows.
