L-shaped hex key set YATO YT-0504, metric, 10 pcs, various arm lengths

YATO YT-0504 is a 10-piece metric L-shaped hex key set designed to provide a compact and versatile solution for tightening and loosening internal hex fasteners. The set contains keys with both short and long arms to reach recessed or hard-to-access screws while allowing greater leverage when needed. Sizes cover common metric hex dimensions used in assembly, maintenance and repair tasks across domestic and professional environments.

Advantages

The L-shaped design offers two working lengths per key, enabling access to confined spaces with the short arm and increased torque with the long arm. Hardened steel construction ensures resistance to bending and wear during repetitive use. The set format of ten metric sizes provides a convenient selection for varied applications without the need to purchase individual keys. Compact storage reduces tool kit volume and makes the set easy to carry to job sites.

Suitable for

• Assembly and disassembly of furniture and fittings
• Maintenance and repair of bicycles and small machinery
• General mechanical and electrical maintenance tasks
• Hobby projects and DIY repairs around the home

Key specifications

• Metric sizes included: 10-piece range of L-shaped hex keys
• Arm configuration: each key has a short arm and a long arm for access and leverage
• Material: hardened steel for increased durability and wear resistance
• Finish: corrosion-resistant surface treatment
• Storage: compact holder for organized transport and storage

How to use

Select the hex key size that matches the internal hex fastener. Insert the short arm into the screw for use in tight spaces or use the long arm as the lever for higher torque when loosening or tightening. Apply steady, controlled force to avoid rounding the fastener head. After use, clean any debris from the keys, then return them to the compact holder to maintain organization and protect the tools from corrosion.

Usage recommendations

For best results, use the appropriately sized key to avoid damaging fasteners; avoid excessive force and use penetrating lubricant on seized fasteners. Store the set in a dry place and inspect keys periodically for wear or deformation before demanding tasks.
