Hex key Proline 2.5 mm, model 48485, 1 pc

Proline 2.5 mm hex key model 48485 is a single L-shaped metric Allen key designed for manual tightening and loosening of hex socket fasteners. Made from quenched and tempered steel with a polished chromium finish, this compact 2.5 mm tool provides precise engagement with small fasteners and is supplied as one piece for straightforward storage and use in workshops, bicycle maintenance, electronics repair and precision assembly tasks.

Advantages

The hex key features heat-treated construction for improved hardness and wear resistance, and a polished chromium finish that helps resist corrosion and eases cleaning. Its L-shaped form offers two leverage positions—short arm for access in confined spaces and long arm for additional torque—while the metric 2.5 mm tip gives accurate fitment to compatible hex socket screws. As a single-piece tool, it is immediately ready for use without additional assembly.

Suitable for

• Precision assembly of small components
• Bicycle adjustments and maintenance
• Electronics and appliance repairs
• General workshop and hobby tasks requiring a 2.5 mm hex drive

Key specifications

• Tool type: L-shaped metric hex (Allen) key
• Nominal size: 2.5 mm
• Quantity: 1 piece
• Material treatment: quenched and tempered steel
• Surface finish: polished chromium
• Drive style: manual hand tool with short and long arm leverage

How to use

Select the 2.5 mm hex key and insert the tip fully into the hex socket of the fastener to ensure a secure fit. Use the short arm for working in tight or recessed areas and the long arm when extra leverage is required; apply steady, controlled force to avoid rounding the fastener head. After use, wipe the tool clean and store it in a toolbox or holder to protect the finish and maintain accurate tip geometry.

Usage recommendations

For best results, pair the hex key with fasteners of the correct metric size and avoid applying excessive torque beyond the fastener or tool rating. Regularly inspect the tip for wear and maintain the polished chromium surface by wiping away dirt and moisture to reduce corrosion risk.
