Combination Wrench Sourcing JCB COMBINATION WRENCH 85mm – 85 mm open/box end

The Combination Wrench Sourcing JCB COMBINATION WRENCH 85mm is a hand tool that combines an open-end and a box-end in a single 85 mm size. Designed for tasks that involve large-diameter bolts and nuts, it provides a practical solution for tightening and loosening fasteners in automotive, construction and industrial maintenance environments. The tool’s steel construction and standard profile ends are intended to deliver consistent torque transfer and dependable workshop performance.

Advantages

This combination wrench offers the convenience of two common end types in one tool, reducing the need to switch between separate wrenches. The open end allows for quick engagement with fasteners in confined spaces, while the box end provides fuller contact around the nut for improved torque application and reduced rounding. The robust steel construction enhances durability under heavy use, and the standard-profile ends ensure compatibility with commonly used bolts and nuts.

Suitable for

• Automotive repair and engine work involving large nuts and studs
• Construction site assembly and structural bolting
• Industrial maintenance of machinery and heavy equipment
• Workshop and garage use for service and repair tasks

Key specifications

• Tool type: Combination wrench with open-end and box-end
• Size: 85 mm across flats
• Material: Steel construction for enhanced strength
• End profile: Standard open-end and standard box-end profiles for common fastener compatibility
• Finish: Workshop-grade finish suitable for regular use

How to use

Select the combination wrench by matching the 85 mm opening to the fastener size. Use the open end for quick placement and for working where the box end cannot access the fastener. Use the box end to apply higher torque and to reduce the risk of rounding the fastener head. Position the box end fully around the nut or bolt head and apply steady, controlled force. Inspect the wrench and fastener for wear or damage before use, and ensure hands and work area are clear of pinch points while operating the tool.

Usage recommendations

For safe and effective use, pair the wrench with appropriate safety equipment such as gloves and eye protection when working in workshops or on heavy machinery. Avoid using extension pipes or cheater bars on the wrench to increase leverage, as this can exceed the tool’s design limits and cause damage or injury. Store the wrench in a dry place and periodically check for signs of wear, corrosion or deformation to maintain reliable performance.
