Wrench EPM flat-ring with ratchet 17 mm E-400-2117

The EPM flat-ring wrench with ratchet 17 mm (model E-400-2117) is a hand tool designed for tightening and loosening hex nuts and bolts with a 17 mm head. The tool combines a flat open-end on one side and a ratcheting ring on the other, enabling access in tight spaces and allowing continuous turning without frequent repositioning. Its combination design makes it suitable for tasks in automotive repair, mechanical assemblies and general maintenance where a 17 mm fastener is used.

Advantages

The flat open end provides a low-profile grip for working in confined areas while the ratcheting ring end delivers continuous rotational action for faster operation. The ratchet mechanism reduces the need to remove and reposition the wrench, improving efficiency in repetitive tasks. Constructed for hand-tool use, the wrench offers straightforward compatibility with standard 17 mm hex fasteners and a balanced length for leverage without excessive bulk.

Suitable for

• Automotive repair and maintenance tasks involving 17 mm nuts and bolts
• Mechanical assemblies and equipment servicing in workshops
• General household and industrial maintenance where access is limited
• Assembly and disassembly of parts in confined or recessed spaces

Key specifications

• Wrench type: combination flat open end with ratcheting ring end
• Size: 17 mm working profile
• Intended use: manual tightening and loosening of hex fasteners
• Profile: standard hex profile compatible with 17 mm nuts and bolts
• Operation: ratcheting action on ring end for continuous turning

How to use

Select the 17 mm profile and place the flat open end or the ratcheting ring over the nut or bolt head. Use the flat open end when working in very tight clearances where the ring cannot reach, and use the ratcheting ring end when continuous rotation is needed without removing the tool. Apply steady hand force appropriate for the task; avoid excessive impact or use with powered extensions. Reverse the ratchet direction if required by the mechanism to tighten or loosen fasteners.

Usage recommendations

Inspect fasteners and the wrench before each use to ensure correct fit and avoid rounding. Use the ratcheting ring for repeated turns to increase speed and the flat end for initial engagement or when space is restricted. Store the wrench in a dry place and clean after use to maintain ratchet performance.
