Impact ring wrench GEKO 17 mm for hammering (10/100)

Impact ring wrench GEKO 17 mm for hammering is a single-size 17 mm ring spanner engineered to transfer shock forces from hammer blows directly to fasteners. Designed for workshop, maintenance and mechanical repair tasks, this tool provides a vibration-resistant connection to nuts and bolts when controlled hammer strikes are required. The tool's geometry and solid construction focus impact energy on the fastener while protecting the operator from slippage during heavy-duty loosening or tightening operations.

Advantages

The GEKO 17 mm impact ring wrench is built to withstand repeated hammer impacts without deforming, offering consistent contact with the fastener and reduced rounding of corners. Its ring end ensures a secure engagement around the nut or bolt head, improving torque transfer during percussive applications. The single-size design simplifies selection for tasks requiring a 17 mm interface and reduces the need to switch tools frequently.

Suitable for

• Workshop assembly and disassembly where hammering is used to assist turning
• Maintenance and repair of machinery with seized or stiff fasteners
• Automotive jobs requiring controlled impact on 17 mm nuts and bolts
• Field service and heavy equipment maintenance where vibration-resistant contact is important

Key specifications

• Size: 17 mm ring opening for standard nuts and bolt heads
• Type: impact ring wrench designed for hammer striking
• Material/Construction: forged metal suitable for shock load transfer (manufacturer-specified alloy not included)
• End style: closed ring end to ensure full peripheral contact with fastener
• Intended use: percussive application with manual hammer strikes

How to use

Position the ring end fully over the 17 mm nut or bolt head to ensure complete engagement. Hold the wrench steady and apply controlled hammer strikes to the opposite end of the wrench, directing impact energy through the tool into the fastener. Use measured force to avoid damaging the fastener or surrounding components; increase striking intensity gradually if the fastener does not move. After initial impact loosening, finish turning the fastener by hand or with an appropriate torque tool as required.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves when applying hammer strikes. Inspect the wrench for cracks or deformation before use and do not use if any damage is present. For rusted or severely seized fasteners, consider applying penetrating lubricant and allowing it time to work before percussive attempts. Do not use the tool with powered striking devices unless explicitly rated for such use by the manufacturer.
