Hex key Proline 14 mm, model 48471, single-piece L-shaped Allen wrench

Proline 14 mm hex key model 48471 is a single-piece L-shaped Allen wrench designed to provide a fixed-size tool for tightening and loosening 14 mm hex fasteners. Manufactured from quenched and tempered steel and finished with polished chromium, this hex key combines strength and corrosion resistance in a compact L-shaped form that offers reliable torque transfer and straightforward handling in mechanical, assembly and maintenance tasks.

Advantages

The single-piece construction ensures rigidity and consistent performance under load, while the quenched and tempered steel core provides improved toughness and wear resistance. The polished chromium finish enhances corrosion protection and facilitates cleaning, and the L-shaped design gives two working lengths for access and leverage, enabling controlled torque application and easier reach into confined spaces.

Suitable for (tasks / use cases)

• Tightening and loosening 14 mm hex bolts and screws in machinery and equipment
• Assembly work where a fixed-size Allen wrench is required
• Maintenance and repair tasks that need a durable hand tool with good torque control
• Situations requiring access to recessed or hard-to-reach hex fasteners

Key specifications

• Size: 14 mm hex drive
• Design: L-shaped, single-piece allen wrench
• Material treatment: quenched and tempered steel for enhanced strength
• Finish: polished chromium for corrosion resistance and easy cleaning
• Working lengths: two different arm lengths for reach and leverage

How to use

Select the 14 mm end and insert it fully into the hex fastener to ensure full contact between the wrench and fastener faces. Use the short arm for higher torque applications and the long arm for increased reach or lower torque turning. Apply steady, controlled force to avoid rounding the fastener head. After use, wipe the tool clean of debris and moisture to maintain the polished chromium finish and store in a dry tool box or rack.

Usage recommendations

For best results, use the appropriate arm length to match the torque requirement and access limitations. Avoid applying impact forces with the hex key, and inspect the contact faces regularly for wear to prevent damage to fasteners.
