Combination wrench NEO tools 46 x 500 mm, open and box-end spanner, size 46 mm, length 500 mm

Combination wrench NEO tools 46 x 500 mm is a heavy-duty hand tool designed for fastening and loosening nuts and bolts where long reach and high torque are required. One end features an open jaw for rapid placement on fasteners, while the opposite end has a boxed (ring) head for secure engagement and reduced rounding of hex heads. The 500 mm overall length provides leverage for demanding mechanical, automotive and industrial tasks while the 46 mm size matches common large fasteners used in construction and equipment maintenance.

Advantages

The wrench combines an open-ended jaw and a ring end to offer flexibility in confined spaces and on exposed fasteners. Its extended length increases leverage, allowing effective torque application with controlled effort. The ring end ensures more complete contact with the fastener profile, reducing the risk of slippage and damage. The tool is suitable for repeated use in workshop and field environments where robustness and reach are needed.

Suitable for

• Automotive repair and chassis work requiring large fastener access
• Industrial maintenance on machines and equipment with large nuts and bolts
• Construction and structural assembly where extended reach is necessary
• Field service and heavy machinery adjustments under limited working space

Key specifications

• Wrench type: combination (open end + boxed/ring end)
• Size across flats: 46 mm
• Overall length: 500 mm
• Ends: one open-ended jaw, one boxed/ring head
• Intended use: high-torque fastening and loosening of large nuts and bolts

How to use

Select the 46 mm combination wrench for compatible fasteners. Position the open end over the nut or bolt for quick engagement or use the boxed end to fully seat on the fastener profile when higher torque or reduced slippage is required. Apply steady force to the handle, keeping the tool aligned with the fastener axis to avoid rounding. For heavy torque, apply force gradually and use body weight or controlled lever action rather than sudden impacts.

Usage recommendations

Inspect the fastener and wrench before use. Use the boxed end for maximum contact on worn or high-torque fasteners. Avoid using cheater bars or excessive force beyond the tool’s intended manual use. Store the wrench in a dry place to prevent corrosion and check periodically for deformation or damage before continued use.
