Hex key Proline 48547, single L-shaped Allen wrench, size not specified

Proline 48547 is a single L-shaped hex key (Allen wrench) designed for tightening and loosening hex socket fasteners. Made as a single-piece tool, this compact L-shaped design provides accessibility in confined spaces and leverages torque for reliable turning of hex screws in common household, workshop and light mechanical tasks. The size is not specified in the supplied data; the tool is described and used as a standard L-shaped hex key from the Proline range.

Advantages

The L-shaped form factor offers two working lengths to reach recessed fasteners or apply higher torque. A single-piece construction reduces joint failure and ensures consistent alignment between the short and long arms. Its compact shape makes it easy to carry in a toolbox, pocket or repair kit and to use in narrow or hard-to-reach places. The simple tool geometry is compatible with a wide range of hex socket screws commonly used in furniture assembly, bicycles and small machinery.

Suitable for

• Tightening and loosening hex socket screws in furniture assembly
• Bicycle maintenance and minor adjustments
• General mechanical and DIY repairs where a single hex key is required
• Work in confined spaces where a compact L-shaped tool is needed

Key specifications

• Tool type: L-shaped hex key (Allen wrench), single piece
• Material: durable steel (typical for hex keys; exact alloy not specified)
• Design: short arm and long arm for accessibility and leverage
• Finish: plain or treated metal surface for corrosion resistance (exact finish unspecified)
• Application: manual operation for hex socket fasteners

How to use

Select the Proline L-shaped hex key that matches the hex socket size of the fastener. Insert the short or long arm into the screw head depending on the clearance and torque required: use the short arm inserted for higher torque and the long arm inserted for extended reach. Turn clockwise to tighten and counterclockwise to loosen. Apply steady force and keep the key aligned with the screw to avoid rounding the socket. For repetitive tasks, reposition your grip on the long arm to maintain comfortable leverage.

Usage recommendations

Use the hex key only with matching-size hex sockets to prevent slipping and fastener damage. When greater torque is needed, use the short arm as the working end. Inspect the tool periodically for wear or deformation and replace it if the edges become rounded. Store the key in a dry place to limit corrosion and keep it with other hand tools for quick access during assembly or repair tasks.
