Hex key Proline 6 mm – Proline Tools 48465, single metric Allen key

Proline 6 mm hex key (Allen key) is a single metric hand tool designed for driving hex-socket fasteners. Made from quenched and tempered steel with a polished chromium finish, this compact tool provides a precise fit and reliable torque transfer for assembly, maintenance and repair tasks on furniture, machinery and bicycles. The single-size design is convenient for situations where a 6 mm hex is required and when a simple, durable tool is preferred.

Advantages

The hardened construction ensures strength and resistance to bending or wear during repeated use. The polished chromium finish offers improved corrosion resistance and a smooth surface that is easy to clean. Its single-piece, L-shaped form gives good leverage for tightening and loosening fasteners while remaining compact for storage in a toolkit or pocket.

Suitable for

• Assembling and adjusting flat-pack furniture that uses 6 mm hex fasteners
• Maintenance and repair of bicycles with 6 mm Allen bolts
• Light machinery and equipment maintenance where a 6 mm hex key is specified
• Home DIY tasks requiring a single, reliable 6 mm hex tool

Key specifications

• Size: 6 mm metric hex key
• Material treatment: quenched and tempered steel
• Surface finish: polished chromium
• Form factor: L-shaped, single-piece hex key
• Intended use: manual driving of hex-socket fasteners

How to use

Insert the short or long end of the hex key into the hexagonal socket of the fastener, selecting the orientation that provides the required leverage. Turn clockwise to tighten and counterclockwise to loosen, applying steady torque without sudden force. For best contact and to avoid rounding the fastener head, ensure the hex key is fully seated in the socket before applying torque.

Usage recommendations

Inspect the tool and fastener for dirt or damage before use, and avoid applying excessive torque beyond the fastener’s specification. Store the hex key in a dry place to preserve the polished chromium finish and reduce corrosion risk.
