Hex key Proline 48507 — single-piece L-shaped Allen key

Proline 48507 is a single-piece L-shaped Allen (hex) key designed for driving hexagonal socket screws. The tool is forged, quenched and tempered, then finished with polished chromium for enhanced surface protection and smooth handling. Supplied as one compact L-shaped key, it is intended for tasks that require a single fixed-size hex key, offering a simple and robust solution for fastening and adjustment work.

Advantages

The solid one-piece construction provides consistent torsional strength and reduces the risk of bending or breakage during typical tightening or loosening operations. The quenched and tempered steel core combined with a polished chromium finish improves wear resistance and reduces corrosion in workshop and household environments. Its L-shape gives two lever lengths for better torque control and access to recessed fasteners.

Suitable for

• Furniture assembly and disassembly
• Routine mechanical repairs and maintenance
• Domestic DIY tasks requiring a single-size hex key
• Accessing hex socket screws in tight or recessed areas

Key specifications

• Design: single-piece L-shaped hex (Allen) key
• Material treatment: quenched and tempered steel
• Surface finish: polished chromium
• Supply: single key (one size)
• Typical use: manual hand tool for hex socket screws

How to use

Select the Proline L-shaped key and insert the short or long end into the hex socket of the fastener, ensuring a full seating to minimize rounding. Use the long arm for higher leverage when loosening or tightening stubborn screws; use the short arm for confined spaces or finer control. Apply steady, straight torque and avoid excessive force that could damage the fastener head or the key.

Usage recommendations

Keep the key clean and dry after use to maintain the polished chromium finish. For frequent or heavy-duty applications, inspect the working tip for rounding and replace the tool if significant wear appears. Store the key in a tool roll or holder to prevent corrosion and to preserve the edge profile.
