Hex key Proline 10 mm, model 48450 — single metric L-shaped Allen key

Proline 10 mm hex key model 48450 is a single metric L-shaped Allen key designed for use with 10 mm hex socket fasteners. Manufactured from quenched and tempered steel with a polished chromium finish, this tool provides a corrosion-resistant surface and a smooth feel. The L-shape gives both reach and leverage, making it practical for tightening and loosening hex-head screws and bolts in a variety of mechanical and assembly tasks.

Advantages

The solid, quenched and tempered steel construction increases durability and resistance to bending or breaking under torque. The polished chromium finish reduces corrosion and simplifies cleaning, while the single-piece L-shaped design offers dependable leverage and two grip positions for torque and reach. Its 10 mm metric tip ensures compatibility with standard metric hex fasteners commonly used in equipment, furniture and machinery.

Suitable for

• Assembly and disassembly of furniture with 10 mm hex fasteners
• General maintenance and repairs of machinery and equipment
• Workshop and garage tasks requiring a 10 mm Allen key
• Installation tasks where a compact, single-size hex key is needed

Key specifications

• Key type: L-shaped (single piece)
• Size: 10 mm metric tip
• Material: quenched and tempered steel
• Finish: polished chromium
• Use: manual hand tool for hex-head fasteners

How to use

Insert the 10 mm end into the hex socket of the fastener, ensuring a full fit to minimize rounding. Use the short arm for higher torque applications and the long arm for extended reach or better leverage depending on the working space. Apply steady, controlled force and avoid sudden or excessive twisting to protect both the fastener and the tool. After use, wipe clean and store in a dry tool holder to maintain the polished chromium finish.

Usage recommendations

For optimal tool life and fastener integrity, select the appropriate arm for the required torque, avoid using cheaters or extensions that exceed recommended leverage, and store the key in a dry environment to preserve the finish. Inspect the tip before use and replace the key if signs of wear or deformation appear.
