Hex Key 3.0 mm Dedra CRV long | 06F024

Long hex key by Dedra with a 3.0 mm tip, manufactured from chromium-vanadium (CRV) steel for durability and consistent performance. The extended arm length gives additional reach and mechanical leverage when driving hex socket fasteners in repair, assembly and maintenance tasks. The tool is intended for repeated use on recessed or hard-to-access hex bolts and screws found in furniture, bicycles, small machinery and electronic enclosures.

Advantages

The CRV steel construction provides good resistance to bending and wear, helping maintain tip shape and fit. The long arm design increases reach into deep or recessed fasteners and offers improved torque compared with a standard short hex key. Its simple, single-piece construction reduces risk of loosening parts and simplifies storage and handling. The 3.0 mm tip size matches common metric hex socket fasteners for accurate engagement.

Suitable for

• Assembling and adjusting furniture fasteners with deep or recessed sockets
• Maintenance and repair of bicycles and scooters where extra reach is needed
• Servicing small machinery and workshop equipment with metric hex bolts
• Opening and fastening screws in electronic enclosures and appliances

Key specifications

• Tip size: 3.0 mm
• Material: chromium-vanadium (CRV) steel
• Tool type: long hex key (Allen key)
• Design: single-piece, long arm for extended reach and leverage

How to use

Insert the 3.0 mm tip into the corresponding hex socket of the fastener, ensuring full engagement to avoid stripping. Use the long arm for reach and the short arm for higher torque when needed by changing the grip. Apply steady, controlled force and keep the key aligned with the fastener axis. After use, wipe the tool clean and store it in a dry place to limit corrosion and preserve tip geometry.

Usage recommendations

Use the long hex key for recessed screws where a standard key cannot reach; switch to the short arm for greater torque on stubborn fasteners. Avoid applying excessive bending force beyond intended torque limits to prevent tip deformation. Periodically inspect the tip for rounding and replace the tool if the fit becomes loose to prevent damage to fasteners.
