## Long description

Proline 48573 is a single-piece 9 mm metric hex key crafted for driving hexagonal (Allen) fasteners. Made from quenched and tempered steel with a polished chromium finish, this tool offers a precise fit for 9 mm hex sockets and is intended for assembly, maintenance and repair tasks across mechanical, furniture and bicycle work. Its compact single-piece design makes it suitable as a spare or replacement key and easy to store in a toolbox or pocket.
Advantages
The heat-treated (quenched and tempered) steel construction provides enhanced strength and durability while the polished chromium finish resists corrosion and simplifies cleaning. As a single-piece hex key, it delivers stable torque transfer with minimal flex and a reliable contact surface for 9 mm fasteners. Its compact form factor makes it practical for carrying and for use in confined spaces where longer wrenches are impractical.
Suitable for
Assembly of furniture and fixtures requiring 9 mm hex fasteners
Mechanical repairs and maintenance tasks using metric hex bolts
Bicycle adjustments and component replacement with 9 mm Allen fittings
Use as a spare or replacement hex key in tool kits
Key specifications
Tool type: single-piece L-shaped metric hex key
Size: 9 mm across flats
Material: quenched and tempered steel
Finish: polished chromium
Drive style: hex (Allen) drive for internal hex fasteners
Typical uses: assembly, maintenance, repair
How to use
Insert the 9 mm end of the hex key fully into the internal hex socket of the fastener to ensure maximum contact and reduce wear. Apply steady, controlled torque; use the long arm for greater leverage and the short arm for higher torque in tighter spaces. Avoid excessive force that could strip the fastener head or deform the tool. After use, wipe the tool clean and store it in a dry place to protect the polished chromium finish.
Usage recommendations
For best results, select the correct 9 mm hex orientation and ensure the key is fully seated before turning. If a bolt is heavily corroded or rounded, consider using penetrating lubricant and a proper removal method to avoid damaging the tool or fastener.
