Hex Key (Allen Wrench) Dedra 2.5 mm CR-V long, model 06F023

The Dedra 2.5 mm CR-V long hex key (Allen wrench) model 06F023 is a single-piece hex driver made from chrome-vanadium steel. Its 2.5 mm tip fits standard metric hex sockets and the extended length gives additional reach and torque for recessed or hard-to-access fasteners. The tool is intended for tasks where a longer shaft improves access or leverage compared with a standard short key.

Advantages

This long hex key is manufactured from CR-V (chrome-vanadium) steel for improved strength and wear resistance. The extended shaft provides better reach into deep or recessed screw positions and allows greater leverage for loosening or tightening fasteners. The precisely machined hex tip ensures a secure fit in 2.5 mm hex sockets, reducing cam-out and fastener damage. Its compact, single-piece design is easy to store and carry for general maintenance or repair work.

Suitable for

• Assembly and disassembly of furniture with 2.5 mm hex fasteners
• Electronics repair and small appliance maintenance requiring small hex keys
• Bicycle adjustments and component maintenance where deeper reach is needed
• General maintenance and workshop tasks involving 2.5 mm hex screws

Key specifications

• Tip size: 2.5 mm hex
• Material: chrome-vanadium (CR-V) steel
• Design: long/extended shaft for increased reach
• Finish: machined hex tip for precise fit
• Form factor: single-piece straight hex key

How to use

Select the 2.5 mm hex key and insert the tip straight into the hex socket of the screw or bolt to ensure full contact. Apply steady turning force; use the long shaft to reach recessed fasteners or to gain additional leverage when loosening tight screws. For higher torque, use the short end as a handle and the long end inserted into the fastener, or vice versa depending on access and required torque. Avoid applying excessive force that could strip the fastener or damage the tool.

Usage recommendations

Use the tool on correctly sized 2.5 mm hex fasteners only. Keep the key clean and free of debris to maintain a secure fit. For stubborn or rusted fasteners consider applying penetrating lubricant and allow it to work before applying torque. Store in a dry place to prevent corrosion and inspect the tip periodically for rounding or wear; replace if the tip no longer seats securely.
