Hex L‑key Allen wrench set Jonnesway H05SA109S 9 pieces 1.5–10 mm ball end

Jonnesway H05SA109S is a set of nine L-shaped hex (Allen) wrenches in metric sizes from 1.5 mm to 10 mm. Each key features a ball end on the long arm, allowing easier engagement with hex fasteners at an angle and improving reach in confined or recessed spaces. The compact set groups the most commonly used metric sizes for assembly, maintenance and repair work, suitable for both professional technicians and DIY users.

Advantages

The ball-end design on the long arm enables up to approximately 25–30° of angular entry, which helps access fasteners that cannot be reached with a straight approach. The L-shaped profile provides two working lengths: a short arm for higher torque and a long arm for reach. Hardened steel construction ensures durability and resistance to wear, while a clear size marking on each key speeds up selection. The included holder keeps the set organized for transport and storage.

Suitable for (tasks / use cases)

• Assembling furniture and fixtures with metric hex fasteners
• Maintenance and repair of bicycles, scooters and small vehicles
• Servicing machinery and equipment in workshops and industrial settings
• Home DIY projects involving hex-socket screws
• Accessing recessed or angled fasteners in electronics and appliances

How to use

Select the hex key whose tip fits snugly into the socket of the fastener to avoid rounding. For maximum torque, insert the short arm into the fastener and use the long arm as the lever. To access fasteners at an angle or in tight spaces, use the ball end on the long arm and engage it at the required angle, keeping moderate pressure to maintain contact. After use, clean any debris and return keys to the holder to prevent loss and corrosion.

Usage recommendations

Use the short arm for loosening tight fasteners and the long arm for reach and clearance; avoid applying excessive force with the ball end to prevent damage to the fastener. Store the set dry and lightly lubricate if exposed to humid conditions. Choose the closest fitting size to reduce the risk of rounded screw heads.
