Hex L-key screwdriver Proxxon PR22416 — set of 8 L-shaped hex keys (metric)

Proxxon PR22416 is a set of eight L-shaped metric hex (Allen) keys designed for tightening and loosening hex-head fasteners. The tools use the conventional short-and-long arm geometry, giving a combination of leverage for higher torque and reach for confined spaces. The set is intended for a range of mechanical and maintenance tasks where accurate control of hex screws is required.

Advantages

The L-shaped design provides two working positions: a short arm for controlled torque and a long arm for extended reach. Metric sizing ensures compatibility with standard hex fasteners found in machinery, bicycles and many consumer products. Hardened tool steel construction offers wear resistance and retains hex profile fit to reduce rounding of fasteners. The compact set format keeps keys organized and accessible for professional and hobby use.

Suitable for

• Assembly and disassembly of mechanical components
• Bicycle repairs and adjustments
• Maintenance of small machinery and workshop tools
• Service and repair of electronic housings and enclosures
• Hobby and model-making tasks requiring precise fastener control

Key specifications

• Tool type: L-shaped hex (Allen) keys
• Quantity: 8 pieces
• Measurement system: Metric
• Arm geometry: Short arm and long arm configuration
• Material: Hardened tool steel (wear-resistant)
• Finish: Industrial finish to resist corrosion and wear

How to use

Select the hex key that fits snugly into the hex recess of the fastener. For higher torque, insert the short arm into the screw head and use the long arm as the lever; for access in tight spaces, use the short arm as the handle and insert the long arm into the fastener. Apply steady, even force, keeping the key aligned with the fastener to avoid cam-out or rounding. After use, return the keys to their compact holder to maintain organization and prevent loss.

Inspect keys for wear before use and avoid excessive force beyond what the fastener or tool can safely handle. Use correct metric sizes to prevent damage to screw heads. For corrosion-prone environments, wipe and lightly oil the keys after use to prolong service life.
