L-shaped hex key YATO YT-05442 Metric 1 pc — long arm 17 cm, short arm 4 cm

YATO YT-05442 is an L-shaped metric hex key supplied as a single-piece tool. The long arm measures 17 cm and the short arm 4 cm, providing access to recessed or hard-to-reach hex fasteners while allowing increased leverage when needed. The tool is intended for use with metric hex bolts and screws and is suitable for assembly, maintenance and repair tasks in automotive, workshop and household environments.

Advantages

The L-shaped design combines a long arm for reach and torque with a short arm for confined spaces. A single-piece construction provides solid feel and straightforward handling, while metric sizing ensures compatibility with standard metric fasteners. The long 17 cm arm allows improved leverage compared with shorter keys, and the compact 4 cm short arm is convenient for working in tight locations.

Suitable for

• Accessing recessed or deep-set metric hex bolts and screws
• Applying higher torque where leverage is needed
• General assembly and disassembly of metric fastened components
• Automotive repairs and maintenance tasks
• Workshop and household repair jobs in confined spaces

Key specifications

• Tool type: L-shaped hex key (Allen key), metric
• Quantity: 1 piece
• Long arm length: 17 cm
• Short arm length: 4 cm
• Intended fastener type: metric hex bolts and screws

How to use

Insert the appropriate metric hex end into the fastener head, using the short arm when working in tight spaces and the long arm to reach recessed fasteners or to increase leverage. Turn the tool in the required direction to tighten or loosen the fastener, keeping steady pressure to avoid rounding the hex profile. When greater torque is required, use the long arm as a lever and apply force perpendicular to the arm to maintain control. Store the key in a dry place to prevent corrosion and inspect before use for wear or damage.

Usage recommendations

Choose the hex key size that matches the fastener precisely to reduce wear on both tool and fastener. For repetitive or high-torque work, consider using the long arm for leverage and the short arm for fine adjustments. Avoid using the hex key as a pry bar or hammer to maintain shape and fit.
