Combination Spanner Proxxon 23914 14x14 mm, set of 4

Proxxon 23914 combination spanner 14x14 mm is supplied as a set of four identical wrenches designed for tightening and loosening metric 14 mm fasteners. Each tool integrates an open-end jaw and a boxed ring end to provide access in confined spaces while allowing firm torque application on hex heads and nuts. The spanners are intended for workshop and field use where a compact, reliable hand tool is required for mechanical maintenance and automotive repairs.

Advantages

The combination design combines quick placement with the open end and secure engagement with the boxed end, reducing slippage and rounding of fasteners. A uniform 14 mm size across the set simplifies selection when multiple identical fasteners are worked on. The slim profile of the head improves access in tight spaces, and robust construction ensures consistent performance under typical workshop loads. Using matching metric sizing helps maintain correct torque transfer and reduces wear on fasteners.

Suitable for

• Automotive maintenance and repairs involving 14 mm metric bolts and nuts
• Mechanical and industrial maintenance tasks requiring a compact spanner
• General workshop use for assembly, disassembly and adjustments
• Field service work where a small set of identical wrenches is needed

Key specifications

• Tool type: combination spanner with open and boxed ends
• Size: 14 mm jaw across flats
• Set quantity: 4 identical spanners
• Material and finish: hardened steel construction with protective finish for corrosion resistance
• Head profile: slim open-end and 12-point boxed ring for improved access

How to use

Select a 14 mm Proxxon spanner from the set and place the open end over the fastener for quick turning or use the boxed end to achieve a more secure grip when higher torque is required. Apply steady force, keeping the tool aligned with the fastener to avoid rounding. For work in restricted spaces, use the slim head profile to maneuver the boxed end onto the fastener and rotate in short increments if necessary. Inspect the spanner and fastener condition before use and avoid applying impacts or extension bars beyond the tool's intended hand-force design.

Usage recommendations

Use the boxed end for final tightening and loosening under higher torque and the open end for rapid positioning. Keep the spanners clean and store them dry to maintain the protective finish and prevent corrosion. For critical torque applications, confirm torque values with a calibrated torque wrench rather than relying solely on hand tools.
