Flat Spanner MEGA 17 x 19 mm model 34179

Flat spanner MEGA 17 x 19 mm model 34179 is a hand tool with two open ends sized 17 mm and 19 mm. Designed for manual turning of nuts and bolts of the corresponding dimensions, the spanner features a compact flat profile that enables access in confined spaces and straightforward storage in toolboxes. Constructed from steel, it provides the mechanical strength required for routine tightening and loosening tasks in mechanical, automotive and household contexts.

Advantages

The flat profile reduces bulk and allows work in narrow gaps where thicker wrenches cannot fit. Two common metric sizes on one tool eliminate the need to switch between separate spanners for 17 mm and 19 mm fasteners. Steel construction ensures durability and a reliable torque transfer during manual operations. The open-end design offers quick engagement with fasteners and easy repositioning on the nut or bolt.

Suitable for

• Automotive maintenance and repairs involving 17 mm and 19 mm fasteners
• Mechanical assembly, adjustment and maintenance tasks
• Household repairs and furniture assembly where metric nuts and bolts are used
• Use in compact or hard-to-reach locations requiring a flat-profile wrench

Key specifications

• Open-end sizes: 17 mm and 19 mm
• Profile: flat, low thickness for confined-space access
• Material: steel construction for strength and wear resistance
• Hand tool type: double open-end spanner
• Intended use: manual tightening and loosening of nuts and bolts

How to use

Select the open end that matches the nut or bolt size (17 mm or 19 mm). Place the spanner on the fastener so the jaws engage fully on the flats, ensuring a secure fit before applying force. Apply steady manual force to tighten or loosen the fastener, avoiding sudden impacts or excessive leverage that could deform the tool or the fastener. Reposition the spanner as needed for incremental turning in confined spaces.

Usage recommendations

Use the flat spanner for hand-applied torque only; avoid using with extensions or as a hammer. Keep the tool clean and dry to prevent corrosion; inspect jaws periodically for wear or rounding. For high-torque applications, use an appropriately rated socket or torque wrench to prevent damage to fasteners and the spanner.
