Hex Key (Allen Wrench) Dedra 10.0 mm CR-V Long 06F033

Long hex key Dedra 10.0 mm CR-V is a single-piece Allen wrench manufactured from chrome-vanadium (CR-V) steel and designed for turning fasteners with 10.0 mm hex sockets. The long arm gives extended reach and improved leverage, allowing access to recessed or hard-to-reach fasteners while keeping consistent contact with the hex profile. The tool is intended for mechanical, assembly and maintenance work where a durable, accurately sized hex key is required.

Advantages

The chrome-vanadium construction provides enhanced strength and wear resistance for repeated use. The long-arm form factor increases reach and torque compared with a standard short hex key, reducing the need to disassemble surrounding components to reach a fastener. Precise 10.0 mm sizing ensures a secure fit in compatible hex sockets, minimising cam-out and fastener damage when used correctly.

Suitable for

• Mechanical repairs and engine maintenance where recessed hex fasteners are present
• Assembly work on furniture, frames and equipment with 10.0 mm hex sockets
• Maintenance tasks in industrial and workshop environments requiring durable hand tools
• Tightening and loosening large hex screws and bolts in construction or metalworking

Key specifications

• Tool type: long hex key (Allen wrench)
• Size: 10.0 mm hex
• Material: chrome-vanadium (CR-V) steel
• Form factor: long arm for extended reach and leverage
• Finish: corrosion-resistant plated or treated surface (manufacturer typical)

How to use

Select the 10.0 mm long hex key for the corresponding hex socket size on the fastener. Insert the short or long end into the fastener head to establish full contact with the hex profile. Use the long arm to reach recessed fasteners and apply steady torque; hold the shorter arm for greater leverage when loosening tight fasteners. Avoid using the tool as a pry bar or applying excessive impact force to prevent deformation of the hex key or fastener.

Usage recommendations

For safe and effective use, verify the fastener size before applying torque, keep the contact surfaces free of debris, and store the hex key in a dry location. If the fastener is corroded or rounded, consider penetrating lubricant or a socket designed for damaged fasteners instead of increasing force.
