Hex Key (Allen Wrench) Dedra 7.0 mm CR-V Long

Long hex key (Allen wrench) Dedra 7.0 mm CR-V Long is a hand tool made from chrome-vanadium (CR-V) steel, designed for engaging hexagonal socket screws and bolts. Its extended arm length provides greater reach and improved torque leverage, facilitating work on recessed, deep-set or awkwardly positioned fasteners. The tool is suitable for both workshop and home maintenance tasks where a 7.0 mm hex drive is required.

Advantages

The Dedra 7.0 mm CR-V Long combines the strength of chrome-vanadium steel with a long-arm design to deliver durable performance and increased mechanical advantage. Corrosion-resistant material and a precisely machined hex profile help ensure a reliable fit with minimal rounding of fastener heads. The longer reach reduces the need for dismantling nearby components to access fasteners, while the straight long-arm geometry provides a stable grip and predictable torque transfer.

Suitable for

• Accessing recessed or deep-set hex socket screws in machinery and equipment
• Tightening and loosening 7.0 mm hex bolts in assembly and maintenance
• Home repairs and DIY projects requiring extended reach
• Automotive and bicycle maintenance where space is limited

Key specifications

• Tool type: long hex key (Allen wrench)
• Size: 7.0 mm hex
• Material: chrome-vanadium (CR-V) steel
• Design: long arm for extended reach and leverage
• Finish: corrosion-resistant treated surface
• Drive profile: precision-machined hex to reduce slippage

How to use

Insert the 7.0 mm hex end fully into the hex socket of the screw or bolt to ensure maximum contact and reduce the risk of rounding. Use the long arm for reaching recessed fasteners and apply steady, controlled torque. For higher torque needs, hold the short end and turn the long arm; for improved reach and clearance, hold the long arm and turn the short end. Keep the tool and fastener surfaces clean and free of debris to maintain grip.

Usage recommendations

Use the Dedra 7.0 mm CR-V Long within its intended torque range to avoid permanent deformation of the tool or fastener. Avoid using cheater bars or excessive force that can damage the hex profile. Store the hex key in a dry place to preserve the corrosion-resistant finish and inspect the hex profile periodically for wear before use.
