Socket key set Proline Ballp 9 pcs 1.5–10 mm, for hex/ball-end drive

Long hex keys with ball ends that allow access to hex fasteners at up to a 30° angle from the screw axis. The compact set contains nine sizes covering common small to medium hex screws for assembly, maintenance and repair tasks.

Advantages

Ball-end design enables turning screws from an angle, increasing accessibility in confined or obstructed locations. The long shank gives additional reach while maintaining stable torque transfer to the screw head. The set includes a range of commonly used sizes, allowing quick selection for various fasteners.

Suitable for

• Assembly of furniture and equipment
• Maintenance and repair of bicycles and small machinery
• Workshop and field service tasks requiring angled access

How to use

Select the hex key that matches the screw size, insert the ball-end or straight hex end into the screw head and apply steady turning force. For angled access, engage the ball end at the required angle (up to 30°) and turn while keeping alignment as stable as possible. Use the long shank to reach recessed fasteners; avoid excessive force that may round the fastener.

Usage recommendations

Use the correct key size for each screw to prevent rounding. For high torque requirements, use the long arm in the handle position rather than the ball-end angle. Store the set in a toolbox or holder to keep sizes organised and protect the ball ends from damage.
