Chiave combinata Bahco 111Z-1 larghezza 290 mm peso 345 g

The Bahco combination wrench with a width of 290 mm and a weight of 345 g is a hand tool intended for tightening and loosening fasteners in general mechanical and maintenance tasks. Constructed from alloy steel and finished for corrosion resistance, the wrench combines an open-end jaw on one side with a closed, ring-type end on the other to allow access in both free and confined spaces. The tool's dimensions and balanced weight provide a compromise between reach and control for medium-duty applications.

Advantages

The combination design offers two working profiles in a single tool, reducing the need to carry multiple wrenches. The 290 mm width increases reach to access bolts and nuts in recessed or awkward locations, while the 345 g mass contributes to stable handling without adding excessive weight. The hardened working surfaces resist wear, and the corrosion-resistant finish helps maintain usability in workshop and outdoor environments.

Suitable for

• Automotive maintenance and repair tasks
• General mechanical assembly and disassembly
• Plumbing and heating system adjustments in confined spaces
• Field service and maintenance where a versatile hand tool is required

Key specifications

• Tool type: combination wrench (open end + ring end)
• Overall width/length: 290 mm
• Weight: 345 g
• Material: alloy steel with hardened working surfaces
• Finish: corrosion-resistant surface treatment

How to use

Select the appropriate end for the fastener and place the wrench fully over the nut or bolt head to ensure even force distribution on the flats. For tightening, turn the wrench clockwise; for loosening, turn counterclockwise. When using the open end, position the wrench so that force is applied toward the fixed jaw to minimize rounding. Use the ring end in confined situations or when higher torque is required. Avoid using the wrench as a hammer or lever extension; apply steady hand force and, when higher torque is necessary, use a properly sized tool designed for that load.

Recommendations

Inspect the wrench before use for wear or damage to the jaw profiles; replace the tool if deformation or significant wear is present. Store the wrench in a dry place and clean after use to extend service life. Use appropriate personal protective equipment such as gloves and eye protection when working with hand tools.
