Hex key with ball end 6.0 mm, Dedra CRV long — 06F079

Long hex key with a 6.0 mm ball end from Dedra, made of chromium-vanadium (CRV) steel. The tool combines a long arm for extended reach with a ball-shaped tip that permits angled insertion into hex sockets. It is designed for tasks where access is limited by depth or obstructions and for working with fasteners that accept a 6 mm hex key.

Advantages

The CRV construction provides a balance of strength and durability while resisting wear during repeated use. The ball end enables up to approximately 25–30° of off-axis entry, allowing the user to engage hex fasteners that are not aligned with the tool shaft. The extended length of the long arm delivers additional reach for recessed or hard-to-access bolts and screws. The simple, single-piece design minimizes flex and offers reliable torque transfer for assembly and maintenance jobs.

Suitable for

• Mechanical assembly and disassembly of machinery with 6 mm hex fasteners
• Bicycle maintenance where recessed or angled access is required
• Furniture installation and equipment fitting in tight spaces
• General repair and maintenance tasks using 6 mm hex sockets

Key specifications

• Hex key size: 6.0 mm
• Tip type: ball end (allows angled access)
• Material: chromium-vanadium (CRV) steel
• Shape: long arm for extended reach
• Finish: industrial protective finish (factory applied)

How to use

Insert the 6.0 mm hex tip into the mating hex socket, ensuring the ball end seats sufficiently to engage the fastener. For straight access, use the long arm in line with the bolt; for angled access, align the ball end with the socket at the required angle and apply steady turning force. Use controlled torque to avoid rounding the fastener head and check engagement frequently. When working in confined spaces, position the long arm to maximize leverage while maintaining safe hand placement.

Usage recommendations

Use the tool only with compatible 6 mm hex fasteners and avoid excessive force beyond the rated capability of CRV steel to reduce risk of tool deformation or fastener damage. Keep the hex key clean and dry after use and store in a tool holder or rack to protect the tip profile.
