## Long description

Long hex key 4.0 mm from Dedra made of CRV (chromium-vanadium) steel. This long-arm Allen key is designed to drive hex socket fasteners in assemblies, maintenance and repair tasks where additional reach and leverage are required. The extended length allows access to recessed or hard-to-reach screws while retaining a compact cross-section for use in confined spaces. The tool is suitable for workshop, household and professional environments.
Advantages
The CRV steel construction provides a balance of toughness and resistance to wear, reducing the risk of rounding the hex profile under torque. The long arm increases reach and leverage compared with standard keys, enabling easier turning of fasteners located deep within components. A straight, uniform shaft offers predictable torque transfer and improved control when working in tight or constrained areas.
Suitable for
 Accessing recessed hex socket screws in machinery and equipment
 Assembly and disassembly of furniture and metalwork
 Automotive and bicycle maintenance where longer reach is needed
 Workshop and household repair tasks requiring a 4.0 mm hex key
Key specifications
 Hex size: 4.0 mm
 Material: chromium-vanadium (CRV) steel
 Style: long arm (extended reach)
 Finish: metal finish suitable for workshop use
 Application: manual hex socket fastener driving
How to use
Insert the short or long end of the 4.0 mm hex key into the corresponding hex socket of the fastener. Use the long arm to reach recessed screws or to gain additional leverage for loosening tight fasteners; use the short arm for increased torque when space permits. Apply steady, controlled force to avoid stripping the fastener. Inspect the tool and fastener for wear before use and ensure a proper fit before applying high torque.
Usage recommendations
For best results, select the 4.0 mm long hex key when you need extended reach or improved leverage. Avoid using the tool as a pry bar or with excessive impact force. Keep the key clean and dry to prevent corrosion and check the hex profile periodically; replace the tool if the edges become rounded to maintain safe and effective operation.
