Ring wrench extra-long Rockforce 16x18 mm

Ring wrench extra-long Rockforce 16x18 mm is an extra-long closed-head hand tool engineered to access recessed or hard-to-reach fasteners. The double-ended design integrates two metric sizes—16 mm and 18 mm—into a single steel body, providing extended reach and increased lever arm compared with standard ring wrenches. The tool is intended for use in automotive repair, machinery maintenance and general workshop tasks where precision fit and reach are required.

Advantages

The extra-long length improves access to bolts and nuts located in narrow recesses or behind obstructions while maintaining the secure, 12-point contact typical of ring (box) wrenches. A one-piece steel construction offers strength and torsional stability for applying higher torque without deforming the head. Two commonly used metric sizes in one tool reduce the number of tools needed on the workbench and simplify task flow when switching between 16 mm and 18 mm fasteners.

Suitable for

• Automotive repair and engine compartment work where space is limited
• Maintenance of industrial machinery and mechanical assemblies
• General workshop and home repair tasks requiring extended reach

Key specifications

• Sizes: 16 mm and 18 mm closed ends
• Extra-long length for extended reach
• Closed (ring/box) 12-point contact on both ends
• Material: forged steel construction for enhanced strength
• Finish: corrosion-resistant surface treatment

How to use

Select the appropriate end (16 mm or 18 mm) that matches the fastener head. Seat the ring fully over the nut or bolt so that all contact points engage to minimize rounding and slippage. Apply steady torque along the wrench axis; avoid sudden impacts or using the wrench as a hammer. When more leverage is needed, position your body to pull or push smoothly rather than applying sideways force that can damage the fastener or tool.

Usage recommendations

Inspect the wrench before use for wear, cracks or deformation. Use the tool only on correctly sized fasteners to preserve the closed head geometry. For stubborn or rusted fasteners, apply penetrating lubricant and allow it to work before applying higher torque. Store the wrench in a dry toolbox to maintain the surface finish and prevent corrosion.
