Spanner (open-end/box) STANLEY 18 mm, hand tool wrench, model S/95-911-0

Combination spanner STANLEY 18 mm, model S/95-911-0, is a compact hand tool that integrates an open-end and a box-end in a single hardened steel wrench. It is designed for tightening and loosening hexagonal 18 mm nuts and bolts in confined spaces where leverage and precise contact are required. The tool's metal construction balances durability and weight for routine workshop and field tasks.

Advantages

The combination of open-end and box-end provides versatility for different fastening situations without changing tools. Hardened construction improves wear resistance and maintains jaw profile under torque. Its compact length allows access in tight engine bays and machinery housings while delivering sufficient leverage for common fastening jobs. The precise 18 mm sizing ensures stable engagement with fasteners to reduce rounding.

Suitable for

• Automotive repairs and maintenance
• Mechanical assembly and disassembly
• Workshop and industrial maintenance tasks
• Home DIY and general household tasks requiring 18 mm fastening

Key specifications

• Type: Combination spanner (open-end and box-end)
• Size: 18 mm
• Material: Hardened steel construction for durability
• Ends: One open-end and one box-end for dual functionality
• Finish: Corrosion-resistant surface treatment (factory finish)
• Typical length: Compact form factor for access in confined spaces

How to use

Select the spanner and position the appropriate end over the 18 mm nut or bolt head. For initial loosen/tighten in confined space, use the open-end; for higher torque and secure engagement, use the box-end. Apply steady force in the correct rotation direction, keeping the spanner fully seated on the fastener to minimize slipping and rounding. When working on assemblies, support the opposing component as needed to prevent movement.

Usage recommendations

Inspect the spanner before use for visible wear or damage. Use the correct 18 mm end and avoid excessive impact forces or cheater bars which may damage the tool or fastener. Store the wrench in a dry place to maintain the finish and prolong service life.
