Hex L‑key set AWTools AW40528 — ball end, sizes 1.5–10 mm, 9 pieces

AWTools AW40528 is a 9-piece L-shaped hex key set covering metric sizes 1.5–10 mm. Each key features a straight short arm for standard hex drive and a ball end on the long arm that permits angled engagement with fasteners. The compact set is intended for assembly, maintenance and repair tasks where space is limited and includes the most commonly used metric sizes for mechanical, furniture and bicycle components.

Advantages

The ball-end design on the long arm enables up to approximately 25° angled entry, improving access to recessed or awkwardly positioned hex bolts without stripping the head. The L-shaped layout provides leverage from the short arm for higher torque and reach from the long arm for deep-set fasteners. The set’s range of sizes from 1.5 mm to 10 mm covers small to medium metric fasteners commonly found in household, workshop and cycling applications. A compact storage holder keeps keys organized and portable for bench or field use.

Suitable for

• Assembly and disassembly of furniture and fittings
• Maintenance and repairs of bicycles and e-bikes
• General mechanical servicing of appliances and small machinery
• Hobby and DIY projects requiring metric hex keys

How to use

Select the matching hex key size that fits snugly into the fastener head to avoid rounding. Use the short arm as a lever when higher torque is required and the long arm for reach or when a ball-end is needed to approach the fastener at an angle. Insert the straight tip fully for maximum contact when possible; engage the ball end when clearance or alignment requires angled entry. Store keys in the holder after use to keep sizes identified and protect the tips.

Usage recommendations

Apply steady, even force and avoid sudden impacts. For high-torque fasteners, use the short arm or a properly sized tool to minimize risk of rounding. Keep the tools clean and lightly lubricated to reduce corrosion; inspect tips regularly and replace if visibly worn or damaged.
