Wrench (offset ring and open) JCB 27 mm 75° bent

Combined open-end and ring wrench by JCB with a 27 mm size and a 75° offset (bent) head. Designed to reach bolts and nuts in tight, recessed or angled positions where a straight wrench cannot access. The tool combines an open-end jaw on one side and a closed ring on the other, allowing both quick positioning and secure engagement with 27 mm fasteners for mechanical, automotive and general maintenance work.

Advantages

The 75° offset head provides improved access to fasteners located in confined spaces or behind obstructions, reducing the need for disassembly of surrounding components. The combination of open-end and ring profiles offers versatility: the open-end side enables rapid placement on the nut or bolt while the ring side delivers full contact for higher torque and reduced rounding risk. The bent design increases hand clearance and allows work at shallow angles, making it practical for use in engine bays, machinery housings and structural assemblies.

Suitable for

• Automotive repair and servicing where angled access to nuts and bolts is required
• Mechanical and industrial maintenance in confined or recessed locations
• Plumbing or construction applications with limited clearance around fasteners
• Field service and workshop use for 27 mm bolts and nuts

Key specifications

• Wrench type: combination open-end and ring wrench
• Size: 27 mm
• Offset angle: 75° (bent head) for angled access
• Head configuration: open jaw on one end, closed ring on the other
• Intended use: manual tightening and loosening of bolts and nuts

How to use

Select the 27 mm side that matches the fastener. Place the open-end side for quick repositioning or the ring side for full engagement when applying higher torque. Orient the wrench so the 75° offset clears nearby obstacles and provides comfortable hand clearance. Apply steady force, avoiding sudden impacts. When working in tight locations, use the open-end to reposition and the ring end to finish tightening or loosening for secure contact.

Usage recommendations

Use appropriate personal protective equipment and ensure the wrench fully seats on the fastener before applying torque. Avoid using the tool with extensions or cheater bars beyond recommended manual force to prevent damage to the wrench or fastener. Inspect the tool for wear or deformation before use and replace if the ring or jaws show significant rounding or cracks.
