Adjustable spanner Bahco 9031-T Jaw width 21.8 cm Weight 325 g

The BAHCO adjustable spanner 9031-T delivers adjustable jaw capacity in a compact, lightweight body. With a maximum jaw width of 21.8 cm and a mass of 325 g, this tool is intended for manual tightening and loosening of a range of nuts and bolts. The design emphasises versatility and straightforward adjustment for different fastener sizes while remaining easy to handle during extended tasks.

Advantages

The adjustable jaw provides a continuous range of opening sizes, allowing the same tool to fit multiple fastener dimensions without the need for interchangeable heads. The relatively low weight improves manoeuvrability and reduces hand fatigue during repetitive use. Precision-machined contact surfaces ensure stable grip on flats of nuts and bolts, while the durable construction is suitable for routine mechanical and maintenance work.

Suitable for

• General mechanical repairs and maintenance
• Assembly and disassembly of plumbing fittings and fixtures
• Automotive light maintenance and workshop tasks
• Home DIY projects requiring adjustable wrenching
• Field service work where one compact, adjustable tool is preferred

Key specifications

• Maximum jaw width: 21.8 cm
• Weight: 325 g
• Tool type: adjustable spanner / adjustable wrench
• Adjustment mechanism: sliding/spiral (manual thumb adjustment)
• Typical material: forged steel with machined contact faces
• Finish: corrosion-resistant coating or treated surface for wear resistance

How to use

Select the spanner by opening the jaw to a size slightly larger than the nut or bolt to be turned, then adjust the jaw until it fits snugly on the flats. Position the fixed jaw against the direction of force to minimise slippage and apply steady torque. Re-adjust as necessary for different fastener sizes. Use the spanner for manual turning only and avoid using it with impact tools or as a hammer.

Recommendations

Inspect the contact faces before use to ensure clean engagement with fasteners, and avoid excessive force that may deform bolt heads or damage the wrench. Store the tool in a dry place and keep the adjustment mechanism clean and lightly lubricated for smooth operation.
