Hex key set Dedra 1.5–8 mm, 8-piece CRV, blackened

Dedra 1.5–8 mm hex key set contains eight L-shaped hex keys made from chrome-vanadium (CRV) steel with a blackened finish. The set covers sizes from 1.5 mm to 8 mm, providing tools for small to medium hex fasteners commonly found in furniture assembly, mechanical maintenance and general repair tasks. The compact bundle is suitable for storage in a toolbox or workshop drawer and delivers standard hex profiles for secure fit and reliable torque transfer.

Advantages

The CRV steel construction ensures improved strength and wear resistance compared with ordinary carbon steel, while the blackened finish reduces surface corrosion and glare. A complete range of eight sizes eliminates the need to search for individual keys and allows quick selection for different fasteners. The L-shaped design offers both leverage and access to recessed bolts, enabling controlled torque application and versatile use in tight spaces.

Suitable for

• Assembly and installation of furniture and fixtures
• Maintenance and repairs of bicycles, appliances and equipment
• Mechanical and light industrial servicing
• DIY projects and home improvement tasks
• Workshop tool kits and mobile service cases

How to use

Select the hex key matching the fastener size to ensure a snug fit and minimize rounding of the hex socket. Insert the short or long arm into the fastener depending on space and required leverage: use the long arm for reach and the short arm for higher torque. Turn steadily and keep the key aligned with the fastener axis to avoid slippage. For tight bolts, apply gradual force and consider using the long arm as a handle to increase leverage.

Usage recommendations

Inspect keys for damage before use and avoid applying impact or excessive bending forces that exceed the tool’s capacity. Store the set dry to preserve the blackened finish and rinse with dry cloth after use in dirty or damp environments. Use the correctly sized key to prevent fastener damage and maintain safe working practice.
