Hex Key Set YATO YT-0508 — 10-piece hex key pack

YATO YT-0508 — 10-piece hex key pack is a compact set of Allen keys designed for tightening and loosening hex fasteners in workshop, garage and home repair situations. The set includes ten commonly used sizes from 2 mm to 12 mm and is supplied in a practical plastic hanger that keeps tools organised and accessible. Manufactured from chrome vanadium steel CrV 6150 with a hardness of 52–55 HRC, the wrenches combine strength and resilience for general mechanical and assembly work.

Advantages

The set provides a broad range of metric hex key sizes in a single pack, reducing the need to search for individual tools. The plastic hanger allows for neat storage and quick size selection. Chrome vanadium construction and specified hardness ensure durability and resistance to wear under normal tightening and loosening loads. Compact dimensions make the keys convenient to carry and use in confined spaces.

Suitable for

• Assembly and disassembly of furniture and fixtures
• Automotive minor repairs and adjustments
• General workshop and maintenance tasks
• DIY home repair projects
• Precision mechanical fittings and equipment servicing

How to use

Select the hex key that matches the internal hex size of the fastener and insert the shorter or longer arm depending on required leverage and access. For higher torque use the longer arm to increase leverage; for confined spaces use the shorter arm for improved clearance. Apply steady, even force when tightening or loosening to avoid rounding the fastener recess. After use, return the keys to the plastic hanger to maintain organisation and protect the tool set.

Usage recommendations

Use the correct key size to prevent damage to both the fastener and the tool. Avoid using excessive force that exceeds the tool’s mechanical limits. Keep the hex keys clean and dry; store them on the hanger to reduce the risk of corrosion and to ensure quick access when needed.
