Hex (Allen) Key Set Silver 9 pcs, Long Ball-End 1.5–10 mm

Silver 9-piece hex (Allen) key set, Long Ball-End 1.5–10 mm provides a selection of metric hex keys in sizes 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10 mm. Each key features an extended shaft and a ball-end on the long arm to allow angled engagement with hex socket screws, enabling access in confined or hard-to-reach locations. The set is intended for general assembly, maintenance and repair tasks where a range of metric hex sizes and reach are required.

Advantages

The long ball-end design permits up to approximately 25–30° off-axis turning, reducing the need for direct alignment with the screw head. Extended-length keys give additional reach for recessed fasteners while the shorter arm provides leverage for higher torque when needed. Hardened steel construction and a consistent hex profile ensure reliable fit and resistance to rounding under normal use. The compact nine-piece set covers common metric sizes for a broad range of applications.

Suitable for

• Assembling and adjusting bicycles and e-bikes
• Furniture assembly and flat-pack installations
• Light machinery maintenance and workshop repairs
• Electronics and small-device disassembly and servicing
• General household repairs requiring metric hex keys

How to use

Select the key with the matching hex size and insert the short or long arm into the fastener socket depending on required reach and torque. Use the long ball-end arm when access is obstructed or when an angled approach is necessary; the ball geometry allows engagement at an angle to the fastener axis. For higher torque, use the short arm as a handle to turn the key. Apply steady pressure to ensure the hex faces seat fully in the fastener to minimize slippage and wear.

Usage recommendations

Store keys in the supplied holder or a designated rack to prevent loss and maintain organization. Avoid excessive torque that exceeds the fastener or key strength; when a fastener is tight, use proper penetrating lubricant or the correctly sized key on the short arm to reduce risk of rounding. Inspect keys for wear before use and replace any damaged keys to maintain safe and effective operation.
