## Long description

Proline 48449 is a single 9 mm metric hex key (Allen key) designed for tightening and loosening fasteners with a hexagonal internal socket. Manufactured by Proline with a quenched and tempered body and polished chromium finish, this hand tool offers a compact, rigid shape that fits standard 9 mm internal hex bolts and screws used in furniture assembly, mechanical maintenance and general DIY tasks.
Advantages
The quenched and tempered steel construction provides enhanced strength and resistance to bending during torque applications, while the polished chromium finish reduces surface corrosion and facilitates easy cleaning. Its single-piece design ensures simple handling and storage, and the 9 mm head profile matches common metric hex socket sizes for accurate engagement and reduced cam-out.
Suitable for
 Assembly and disassembly of furniture with 9 mm internal hex fasteners
 Light to medium mechanical maintenance and repairs

 Workshop use where a single, robust 9 mm Allen key is needed
Key specifications
 Tool type: single metric hex key (Allen key)
 Size: 9 mm head for internal hex sockets
 Material treatment: quenched and tempered steel for improved strength
 Surface finish: polished chromium for corrosion resistance and easy cleaning
 Design: single-piece hand tool, compact form factor
How to use
Select the 9 mm Proline hex key and insert the short or long end into the internal hex socket of the fastener until it seats fully. Apply steady clockwise rotation to tighten or counterclockwise rotation to loosen, keeping the key aligned with the fastener axis to prevent rounding. Use controlled force appropriate to the fastener's size and condition; avoid using excessive leverage that could damage the tool or fastener. After use, wipe the tool clean and store it in a dry place to preserve the polished surface.
Usage recommendations
Use the Proline 9 mm hex key for tasks matching its size and strength rating; avoid using it on fasteners with damaged or worn hex profiles. For higher torque requirements, consider using a tool specifically designed for heavy-duty applications to prevent tool deformation or fastener damage.
