Combination wrench NEO tools 27 x 310 mm spanner, open and ring ends

Combination wrench NEO tools 27 x 310 mm is a hand spanner with a 27 mm open jaw on one end and a 27 mm ring (box) end on the other, designed for manual tightening and loosening of hexagonal nuts and bolts. With a total length of 310 mm, this tool provides extended reach and improved leverage for tasks in workshops, garages and maintenance environments. The dual-end design allows quick switching between open access and full-contact engagement with fasteners, making it practical for varied service conditions.

Advantages

The 27 x 310 mm combination wrench offers increased torque thanks to its longer handle, while the ring end delivers full-contact engagement to reduce rounding of fastener heads. The open end permits access to nuts in confined spaces and on protruding studs. Constructed to meet common hand tool durability expectations, it is suitable for repetitive manual use and provides reliable mechanical performance for typical automotive and industrial maintenance tasks.

Suitable for

• Automotive repair and maintenance
• Workshop mechanical assembly and disassembly
• Industrial maintenance and service tasks
• Plumbing and HVAC applications where hex fasteners are used
• Situations requiring additional reach or leverage

Key specifications

• Size: 27 mm across flats
• Length: 310 mm overall
• Ends: one open-end jaw and one ring (box) end
• Intended use: manual tightening and loosening of hexagonal nuts and bolts
• Design: combination wrench (open + ring)

How to use

Select the 27 mm end appropriate for the fastener: use the open jaw where access is limited or the ring end for full-surface engagement. Position the chosen end squarely on the fastener, apply steady force on the handle in the correct direction to tighten or loosen, and avoid sudden impacts. For best control, pull rather than push when feasible and keep hands clear of pinch points. Inspect the tool and the fastener before use to ensure proper fit.

Usage recommendations

Use the ring end when higher torque and protection against rounding are required; reserve the open end for quick adjustments in tight spaces. Do not use the wrench as a hammer or apply excessive force beyond manual capacity. Maintain the tool by wiping clean after use and storing in a dry place to prevent corrosion.
