Hex key Proline 48466 — single 7 mm metric Allen key

Proline 48466 is a single metric hex (Allen) key with a 7 mm tip size, designed as a compact, one-piece hand tool for tightening and loosening hex-head fasteners. Made from quenched and tempered steel with a polished chromium finish, the tool provides a rigid shaft and a corrosion-resistant surface. The simple design makes it suitable for tasks in assembly, maintenance and repair where a standard 7 mm hex key is required.

Advantages

The solid, one-piece construction ensures torsional strength and reduces the risk of bending or breakage under typical hand-torque loads. Quenched and tempered steel increases hardness and durability, while the polished chromium finish offers improved resistance to corrosion and easier cleaning. Its compact size allows use in constrained spaces and makes it easy to store in a toolbox or tool roll.

Suitable for

• Assembling and disassembling furniture with 7 mm hex fasteners
• Adjusting machinery and equipment that use metric hex screws
• General workshop and maintenance tasks requiring a 7 mm Allen key
• Repairing bicycles, appliances or fixtures that accept a 7 mm hex wrench

Key specifications

• Tool type: single metric hex (Allen) key
• Tip size: 7 mm
• Material: quenched and tempered steel
• Finish: polished chromium
• Construction: one-piece, fixed-shaft design

How to use

Select the 7 mm end of the Allen key and insert it fully into the hex socket of the fastener to ensure full contact between the key and the screw. Apply steady hand torque to tighten or loosen the fastener, keeping the key aligned with the screw axis to minimize wear on both the tool and the fastener. For high-torque requirements, use controlled force to avoid exceeding the material strength of the key or the screw.

Usage recommendations

Inspect the hex key before use: ensure the tip is free of burrs and the finish is intact. Use the tool only for its intended 7 mm hex fasteners, and avoid applying impact loads. After use, wipe clean and store in a dry place to preserve the polished chromium finish and prevent corrosion.
