## Long description

Dedra JCB-76404 is a 4 mm L-shaped hex key made from steel, designed to drive and manipulate hexagonal socket screws. The compact tool provides a short arm and a long arm to deliver leverage and access in confined spaces. It fits standard 4 mm hex sockets and is intended for general workshop and household tasks where reliable torque and a slim profile are required.
Advantages
The steel construction ensures durability and resistance to bending under normal torque loads. The L-shaped design offers a balance between reach and control: the long arm allows higher torque while the short arm gives better access in tight spots. Its compact size makes it easy to store in a toolbox or carry with other hand tools.
Suitable for
Furniture assembly and adjustment
Bicycle maintenance and component tightening
Small machinery and equipment repairs
Electronics enclosures and interior fasteners
General household repairs and DIY projects
Key specifications
Key type: L-shaped hex (Allen) key
Size: 4 mm across flats
Material: steel
Finish: plain steel surface suitable for workshop use
Shape: short arm and long arm for torque and access
How to use
Select the 4 mm hex key and insert the short or long arm into the hexagonal socket of the screw, depending on required torque and clearance. Use the long arm for greater leverage when loosening or tightening stubborn fasteners; use the short arm when working in limited space for better control. Apply steady, even force and avoid sudden jerks to reduce the risk of rounding the screw head. When not in use, store the tool in a dry place to limit surface corrosion.
Usage recommendations
Use the appropriate arm length for the task: long arm for higher torque, short arm for confined access. Inspect the hex key and fastener before use; if either shows rounding or damage, replace the tool to prevent further wear. For repetitive or high-torque applications consider using a key with a handle or a torque-controlled driver to protect fasteners and the tool.
