Hex Key (Allen Wrench) Dedra 13.0 mm CR-V Long

Long hex key Dedra 13.0 mm CR-V Long is a single-piece Allen wrench manufactured from chrome-vanadium steel. The tool is designed for driving hexagonal fasteners in automotive, mechanical and assembly applications. Its extended long arm provides additional reach and increased leverage for recessed bolts and fasteners located in tight or deep spaces. The chrome-vanadium material offers improved strength and resistance to wear compared with standard carbon steels, making this hex key suitable for repeated use in professional and DIY environments.

Advantages

The long design delivers greater torque and access to recessed hex screws without the need to disassemble surrounding components. Construction from chrome-vanadium steel improves durability and dimensional stability during heavy use. The precisely machined hex profile ensures a secure fit on fasteners, reducing the risk of rounding heads and slippage. Corrosion-resistant surface treatment extends service life and helps maintain reliable performance in workshop conditions.

Suitable for

• Automotive maintenance and repairs where access is limited
• Mechanical assembly and disassembly of machinery
• Furniture and equipment installation with recessed hex bolts
• Hobby and DIY projects requiring a durable long-reach hex key

Key specifications

• Tool type: long hex key (Allen wrench)
• Size: 13.0 mm hex drive
• Material: chrome-vanadium (CR‑V) steel
• Design: single-piece, long arm for extended reach
• Finish: corrosion-resistant surface treatment

How to use

Insert the 13.0 mm hex end fully into the hexagonal recess of the fastener to ensure a stable fit. Apply steady rotational force using the long arm to turn the fastener; for higher torque, hold the short arm and use the long arm as the lever. When working in confined spaces, align the tool carefully to avoid slipping and ensure the hex key engages all sides of the fastener. After use, clean off debris and store in a dry place to preserve the corrosion-resistant finish.

Usage recommendations

Use the tool within its size range and avoid applying impact or excessive bending forces. For seized or rounded fasteners, inspect the hex profile and consider alternative methods to prevent harming the tool or fastener. Regularly inspect the hex key for wear and replace if the profile becomes deformed.
