Ring Spanner Extra Long 17x19 mm JCB JCB-7601719

Extra-long ring spanner 17x19 mm by JCB, model JCB-7601719, is a hand tool with closed ring ends in two metric sizes on opposite sides. The extended length provides additional reach to access recessed, confined or awkwardly positioned fasteners while maintaining a secure fit and effective torque transfer. The tool is intended for professional and hobbyist mechanical, automotive and maintenance tasks where standard spanners cannot reach.

Advantages

The extra-long design increases reach without sacrificing control, enabling safer engagement with nuts and bolts in deep or narrow spaces. Closed ring ends offer full contact around the fastener head to reduce slippage and distribute torque evenly. Durable construction and a precision-formed profile ensure consistent fit and resistance to rounding under load. The dual-size configuration (17 mm and 19 mm) allows quick switching between adjacent fasteners without changing tools.

Suitable for

• Automotive repair and servicing where deep-set fasteners are encountered
• Mechanical assembly and disassembly in machinery with limited access
• General maintenance tasks in workshops, garages and industrial environments
• Plumbing and installation jobs that require reach into confined fittings

Key specifications

• Tool type: Extra-long double-ended ring spanner with two closed ends
• Sizes: 17 mm and 19 mm ring ends
• Finish: durable industrial finish for corrosion resistance and wear protection
• Profile: precision-formed ring for secure engagement and torque transfer
• Length: extended reach compared with standard ring spanners (extra-long geometry)
• Material: forged alloy steel designed for strength under load

How to use

Select the appropriate ring end (17 mm or 19 mm) that matches the fastener size. Position the closed ring fully over the fastener head to ensure full contact before applying force. Use steady, controlled torque to loosen or tighten bolts, avoiding sudden impacts that can damage the tool or fastener. When working in confined spaces, ensure sufficient clearance for turning the spanner and maintain a firm grip on the handle; if necessary, reposition the tool incrementally by loosening in small turns.

Usage recommendations

Use the spanner for manual turning only and avoid using with chemical cleaners or extreme heat. Inspect the ring faces for wear before use and replace the tool if rounding or significant deformation is present. For high-torque applications, consider using appropriate torque tools or sockets designed for those loads to avoid overstressing the spanner.
