Hex key Proline 48505 — single L-shaped Allen key, metric (1 piece)

Proline 48505 is a single L-shaped hex (Allen) key designed for driving metric hex-socket fasteners. The tool is quench- and temper-treated for strength and finished with polished chromium for corrosion resistance and a smooth surface. Its compact L-shape offers both reach and torque for tightening and loosening bolts and screws in confined areas where a handheld hex key is required.

Advantages

The hardened and tempered steel construction provides durability and resistance to wear during repeated use. The polished chromium finish reduces surface corrosion and eases cleaning while offering a consistent feel in the hand. The L-shaped design combines a short end for high-torque applications and a long end for access to recessed fasteners, making it a versatile basic tool for mechanics, DIYers and maintenance personnel.

Suitable for

• Assembly and disassembly of furniture and fixtures
• Maintenance and repair of mechanical equipment
• Adjusting components in tight or recessed spaces
• General workshop and household fastening tasks

Key specifications

• Type: L-shaped (single piece) hex key
• Measurement system: Metric
• Material treatment: Quenched and tempered steel
• Surface finish: Polished chromium
• Design features: Short end for torque, long end for reach

How to use

Insert the appropriate end of the L-shaped hex key into the hex socket of the fastener. Use the short end for maximum torque when loosening or tightening, or use the long end to reach recessed fasteners and to provide controlled turning. Apply steady, even force to avoid rounding the fastener head and ensure the tool is fully seated in the socket before applying high torque. Clean and store the hex key in a dry place after use to preserve the polished chromium finish.

Usage recommendations

Choose the correctly sized metric hex key to match the fastener. Avoid using cheater bars or excessive force that can overstress the tool or damage fasteners. Periodically inspect the working tip for wear and replace the key if the edges show rounding to maintain effective engagement with hex sockets.
