## Summary description

It serves for tightening and loosening hex (Allen) fasteners in mechanical, assembly and maintenance tasks.

## Long description

YATO YT-05574 is a single-piece hex key designed for manual tightening and loosening of hex (Allen) fasteners. Supplied as one unit per pack, this compact tool combines a molded handle with a straight mandrel to provide grip and control in assembly, maintenance and repair tasks where a single size 4.0 mm hex wrench is required. Its construction is intended for repeated use in workshop and automotive environments.
Advantages
The tool features an ergonomic plastic handle that improves torque control and comfort during use, paired with a durable S2 steel mandrel for strength and wear resistance. The one-piece design reduces play between handle and shaft, offering dependable alignment with hex socket screws and bolts. Its compact form factor makes it easy to store and carry in a toolbox or on a workbench.
Suitable for
 Manual tightening and loosening of 4.0 mm hex (Allen) fasteners
 Automotive repair and maintenance tasks
 Mechanical assembly and workshop use
 Field service and portable tool kits
Key specifications
 Mandrel (hex) size: 4.0 mm
 Handle type: molded plastic ergonomic handle
 Mandrel material: S2 steel
 Design: single-piece hex key with straight shaft
 Intended use: manual operation for hex socket screws and bolts
How to use
Insert the 4.0 mm hex mandrel into the corresponding hex socket of the fastener, ensuring full engagement to avoid rounding the screw head. Apply steady torque using the molded handle, turning clockwise to tighten and counterclockwise to loosen. For higher torque requirements, apply gradual force and reposition grip as needed to maintain control. After use, wipe the mandrel clean and store the hex key in a dry toolbox to prevent corrosion.
Usage recommendations
Use the hex key only with matching 4.0 mm hex fasteners and avoid using excessive impact force. Inspect the S2 steel mandrel for wear or damage before use; replace the tool if the hex edges become rounded. Store in a dry place and keep away from chemicals that may degrade the plastic handle.
