Combination wrench NEO tools 30 mm x 340 mm

Combination wrench NEO tools 30 mm x 340 mm combines an open-end jaw and a boxed (ring) end of the same 30 mm size in a single 340 mm-long steel tool designed for turning nuts and bolts. The tool’s length provides increased leverage for higher torque while the boxed end delivers full contact on fasteners and the open end allows quick placement on bolts in tight or partially obstructed positions. This wrench is intended for use in automotive repair, machinery maintenance, assembly work and industrial service where access and turning force are required.

Advantages

The full-profile boxed end reduces rounding of fasteners by offering multiple points of contact, while the open end enables rapid repositioning and use in confined spaces. At 340 mm length the wrench gives improved mechanical advantage for loosening or tightening medium to large fasteners without the need for additional extensions. Constructed from hardened steel with a finish that resists corrosion, the tool balances durability with everyday usability and is compatible with common metric fastener sizes in professional and hobby settings.

Suitable for

• Automotive repair and maintenance where 30 mm fasteners are used
• Industrial and factory equipment maintenance
• Heavy machinery assembly and disassembly
• Field service and mobile repair tasks requiring extended leverage
• Workshop and garage use for tightening and loosening bolts

Key specifications

• Size: 30 mm jaw (open and boxed ends)
• Length: 340 mm overall
• Design: combination wrench with open-end and boxed (ring) end
• Material: hardened steel construction (wear-resistant)
• Finish: corrosion-resistant surface treatment

How to use

Select the 30 mm end that best fits the fastener and position the wrench so the boxed end fully engages the nut or place the open end onto the fastener where clearance is limited. Apply steady, controlled force in the required direction to tighten or loosen the fastener; use the length of the wrench to increase leverage when needed. Avoid sudden jolts or impact loading that can damage the wrench or fastener. After use, clean off any grease or debris and store the wrench in a tool drawer or rack to prevent corrosion.

Usage recommendations

Use the boxed end for maximum torque and to minimize rounding of hex heads; use the open end when working in restricted spaces. For very tight fasteners, apply steady pressure and consider penetrating oil or gradual incremental turns rather than sudden force. Inspect the wrench for wear or deformation before use and replace it if the profile is distorted.
