Hex Key YATO YT-05591 — single-piece Allen wrench, L-shaped, metric

YATO YT-05591 is a single-piece L-shaped metric hex key supplied as one unit per pack. Designed for driving hexagonal socket screws and bolts, this Allen wrench combines a straight mandrel with a plastic handle to provide a compact, hand-held tool for assembly, maintenance and repair tasks in workshop, automotive and household environments.

Advantages

The hex key features a mandrel made of S2 steel for durability and wear resistance under repeated torque. The 6.0 mm stem size gives defined contact with metric hex fasteners, while the solid plastic handle improves grip and allows more comfortable manual operation compared with a bare L-bar. As a single-piece L-shaped design, it is simple to store and quick to position in confined spaces.

Suitable for

• Assembly and disassembly of furniture and fittings with metric hex screws
• Automotive maintenance tasks requiring metric hex fasteners
• General mechanical and workshop repair where a 6.0 mm hex key is needed
• Household repairs involving hex socket bolts

Key specifications

• Type: L-shaped single-piece hex key (Allen wrench)
• Material of mandrel: S2 steel
• Handle: solid plastic
• Stem (hex) size: 6.0 mm
• Pack quantity: 1 piece

How to use

Select the YATO YT-05591 hex key for a matching 6.0 mm metric hex socket. Insert the short or long end into the screw head as space allows and apply steady torque by turning the handle. For tightening, turn clockwise; for loosening, turn counterclockwise. Use the longer arm for reach or leverage and the shorter arm for higher torque in tight spaces. Avoid excessive force beyond the tool or fastener rating to prevent rounding of the hex socket or bending of the mandrel.

Usage recommendations

Keep the hex key clean and dry after use to reduce corrosion risk. Inspect the mandrel for wear before applying high torque and replace the tool if the hex edges become rounded. Use appropriate personal protective equipment when working on automotive or mechanical systems.
