Hex Key Set Polax 25-010 — long ball-end, 9 pcs, sizes 1.5–10 mm

Set of 9 long ball-end hex keys by Polax, sizes 1.5–10 mm, designed to reach recessed or angled fasteners. The long arms deliver extra reach and leverage while the ball-end tips permit working at an angle, enabling access in confined spaces where straight entry is impractical. This set suits general assembly, maintenance and repair tasks in workshop, home and light industrial environments.

Advantages

The long-arm design increases reach and torque compared with standard short keys, while the ball-end geometry allows up to approximately 25–30° of angled engagement for improved access to offset screws. Hardened steel construction provides wear resistance for repeated use, and the graduated size range from 1.5 mm to 10 mm covers the most common metric hex fasteners. The compact set keeps keys organized and readily available for both precision and heavy-duty tasks.

Suitable for

• Assembly of furniture and household fixtures
• Maintenance and repair of bicycles, machinery and equipment
• Electronics and small appliances where angled access is required
• Workshop use for fastening in recessed or hard-to-reach locations

How to use

Select the hex key matching the fastener size and insert the short or long arm as needed to achieve best leverage or reach. For tight or offset applications, engage the ball-end tip at an angle to allow insertion where straight alignment is blocked; apply steady torque and avoid sudden twisting to prevent rounding the fastener head. After use, store keys in the provided organizer to keep sizes identified and prevent loss.

Usage recommendations

Use the correct size to minimize wear on both key and fastener. For maximum torque, use the long arm as a lever and the short arm for initial alignment. Avoid using keys as pry bars or applying excessive force beyond typical fastening requirements; inspect tips regularly for rounding or damage and replace the set if significant wear is present.
