Hex Ball-End Allen Key Set 9 pcs, Sourcing YT.IMBUSES 1.5–10 mm

The Sourcing YT.IMBUSES Hex Ball-End Allen Key Set 9 pcs (1.5–10 mm) is a compact hand tool kit that provides access to hex socket screws where straight entry is not possible. Each key in the set features a ball-end geometry on the long arm and a standard hex tip on the short arm, enabling both angled engagement and firm torque application for a range of general maintenance and assembly tasks.

Advantages

The ball-end design permits up to approximately 25–30° of angled access, reducing the need to position the workpiece for straight-line entry. A full range of metric sizes from 1.5 mm to 10 mm covers small electronics fastenings through larger mechanical bolts. The compact set is easy to store and keeps commonly used sizes together for quick selection during repair or assembly jobs.

Suitable for

• Mechanical assembly and general workshop tasks
• Bicycle maintenance and component adjustments
• Automotive interior and light mechanical repairs
• Electronics and small equipment fastening
• Situations requiring angled access to hex socket screws

How to use

Select the hex key that fits the socket screw snugly. For straightforward torque, insert the short arm into the socket and use the long arm as a lever. For restricted access or angled approach, engage the ball-end on the long arm and apply torque while maintaining alignment within the ball-end tolerance. Avoid using the keys as prying tools or applying excessive impact force. Inspect keys for wear or rounding before use to prevent damage to fasteners.

Usage recommendations

Use the appropriate size to minimize rounding of screw heads, and apply steady, controlled force. Store the set in its holder to protect tips and keep sizes organized. For high-torque applications, use the short arm for leverage and consider using a torque-limiting tool if specified by the equipment manufacturer.
