Hex Key (Allen Wrench) Dedra 8.0 mm, CRV steel, long

Long hex key Dedra 8.0 mm in CRV steel is a single-piece Allen wrench designed for working with hexagonal socket screws and bolts. Its long arm provides extended reach and improved leverage for fasteners located in recessed or hard-to-access areas. Made from chromium-vanadium (CRV) steel, the tool is intended for routine use in automotive repairs, bicycle maintenance, furniture assembly and general workshop tasks where a durable, straight hex key is required.

Advantages

The long 8.0 mm hex key offers greater reach compared with standard short keys, making it easier to access deeply set screws while maintaining control and torque. CRV steel construction provides a balance of strength and toughness to resist bending under normal working loads. The simple, straight L-shape gives predictable leverage and a reliable fit into hex sockets, reducing the risk of rounding fastener heads when used correctly.

Suitable for

• Automotive repair and maintenance tasks requiring access to recessed hex bolts
• Bicycle assembly and adjustment where extended reach is needed
• Furniture assembly and installation of fittings with hex socket screws
• General workshop and DIY applications involving 8.0 mm hex fasteners

Key specifications

• Size: 8.0 mm hex key
• Material: chromium-vanadium (CRV) steel
• Shape: long L-shaped (extended arm for reach and leverage)
• Finish: plain metal surface suitable for workshop use
• Single-piece construction for rigid performance

How to use

Insert the short or long end of the hex key into the hex socket of the fastener so the tool seats fully to ensure even load distribution. Use the long arm to reach recessed fasteners or to gain extra leverage when loosening tight bolts; use the short arm for higher torque in confined spaces. Apply steady, controlled force and avoid sudden impacts. After use, clean off dirt or grease and store the key in a toolbox or holder to prevent corrosion and loss.

Usage recommendations

Select the 8.0 mm hex key only for fasteners that match the size to prevent stripping. When more torque is required, use the short arm as the driver and the long arm for reach, and avoid applying excessive force that might deform the tool or fastener.
