Hex key Proline 2.5 mm model 48461 — single metric Allen key

Proline 2.5 mm hex key model 48461 is a single metric Allen key designed for precise engagement with 2.5 mm hex fasteners. The tool is quenched and tempered for strength and finished with polished chromium for corrosion resistance and smooth handling. Its compact L-shape provides leverage in tight spaces and reliable torque transfer for maintenance, repair and assembly work across mechanical, electronic and furniture applications.

Advantages

The Proline 2.5 mm hex key offers a hardened steel construction that resists bending and wear during repeated use. The polished chromium finish improves corrosion resistance and eases cleaning while providing a comfortable surface to grip. Its single-piece design eliminates moving parts and provides consistent alignment with fastener heads, enabling accurate tightening and loosening of small hex screws.

Suitable for

• Mechanical assembly and adjustments where 2.5 mm hex fasteners are used
• Electronic device maintenance and small appliance repairs
• Furniture assembly and fittings with metric Allen screws
• Hobby, model building and DIY tasks requiring a precise 2.5 mm driver

Key specifications

• Tip size: 2.5 mm metric hex
• Shape: L-shaped (single-piece) Allen key
• Material treatment: quenched and tempered for improved hardness
• Surface finish: polished chromium for corrosion resistance
• Use environment: suitable for confined spaces and small fasteners

How to use

Insert the 2.5 mm tip fully into the hex recess of the fastener to ensure proper engagement. Apply steady torque using the long arm for greater leverage or use the short arm for access in tight spots. Turn clockwise to tighten and counterclockwise to loosen, keeping the tool aligned with the fastener to avoid rounding the corners. After use, wipe the surface to remove debris and store the key in a dry place to preserve the polished chromium finish.

Usage recommendations

Use the Proline 2.5 mm hex key only with matching 2.5 mm hex fasteners to prevent damage to tool and screws. Avoid excessive force beyond the tool’s leverage limits; for stubborn fasteners, inspect fastener condition and consider applying penetrating lubricant rather than applying extreme torque. Regularly check the tool tip for wear and replace if rounding appears to maintain secure engagement.
