## Long description

YATO YT-05440 is a single-piece hex key (Allen wrench) designed for driving hexagonal socket fasteners. Supplied as one piece per pack, this compact tool is intended for general-purpose assembly, maintenance and repair tasks in workshops, garages and domestic settings where a standard hex key is required.
Advantages
The tool is made from chrome-vanadium steel, providing strength and resistance to bending and wear during repeated use.

Key specifications
 Construction: single-piece hex key (L-shaped Allen wrench)
 Material: chrome-vanadium steel for enhanced durability
 Finish: corrosion-resistant surface treatment (typical for chrome-vanadium tools)
 Supply: sold as one piece per pack
How to use
Insert the short or long arm of the hex key into the hexagonal socket of the fastener, choosing the arm that provides suitable leverage and clearance. Turn clockwise to tighten and counterclockwise to loosen. Apply steady, even force and avoid sudden torque spikes that could round the fastener head. For high-torque applications, use the longer arm for increased leverage; for confined spaces, use the shorter arm. Keep the tool clean and free of debris to maintain a secure fit with the fastener.
Usage recommendations
Match the hex key to the fastener size before applying force. Do not use the hex key as a pry bar, chisel or hammer. Store in a dry place to prevent corrosion and inspect regularly for wear or deformation; replace if the hex profile shows rounding or damage.
