Combination wrench King Tony 5.5 mm model 1060-55, open-end and box wrench

The King Tony combination wrench 5.5 mm (model 1060-55) is a compact hand tool featuring an open-end jaw on one side and a boxed ring end on the other. It is designed to tighten and loosen 5.5 mm nuts and bolts with accurate fit and reliable torque transmission. The tool’s slim profile and offset ring end improve access in confined spaces, making it suitable for precision work on small fasteners encountered in mechanical, electrical and assembly tasks.

Advantages

The combination of an open-end and a box end provides versatility: the open jaw allows quick engagement on fasteners while the ring end delivers full-contact gripping for higher torque and reduced rounding. Hardened construction and a finished surface offer durability against wear and make the wrench easy to clean. The compact 5.5 mm size and slim shank allow access to tight areas that larger wrenches cannot reach.

Suitable for

• Precision mechanical repairs on small machinery and instruments
• Electrical and electronic component assembly and maintenance
• Bicycle and small vehicle adjustments where 5.5 mm fasteners are used
• General workshop and household tasks requiring a small, accurate wrench

Key specifications

• Wrench type: combination (open-end and box/ring end)
• Usable fastener size: 5.5 mm
• Material and treatment: hardened tool steel with finished surface
• Profile: slim shank for access in confined spaces; offset ring end for improved clearance
• Grip style: fixed single-piece construction for direct torque transfer

How to use

Select the 5.5 mm end that best fits the fastener and position the wrench squarely on the nut or bolt head to avoid slipping. Use the open end for quick placement and initial turning; switch to the box end when higher torque or safer, full-contact engagement is required. Apply controlled force and avoid sudden impacts or use as a hammer. For work in confined areas, use the slim shank and offset ring to reach recessed fasteners while maintaining a steady grip.

Usage recommendations

Inspect the wrench before use for signs of wear or deformation. Clean and lightly lubricate after exposure to moisture to prevent corrosion. Do not use cheater bars or extend the handle; use the correct size and appropriate tools for high-torque applications to prevent tool damage and fastener rounding.
