## Summary description

Proline hex key 48445 is a single metric Allen (hex) key with a 5 mm size. Designed for tightening and loosening hex fasteners, this compact hand tool suits assembly, maintenance, and repair tasks on furniture, machinery and bicycles. Its single-piece supply makes it convenient for occasional use or as a replacement tool in a toolkit.

## Long description

Proline 5 mm hex key 48445 is a single metric Allen key designed for tightening and loosening hex-head fasteners. Manufactured from quenched and tempered steel with a polished chromium finish, this compact, single-piece tool provides a rigid, wear-resistant working tip and a smooth surface that resists corrosion. The straight-shank design and moderate length offer reach and leverage suitable for general assembly, maintenance and repair tasks on furniture, machinery and bicycles.
Advantages
The quenched and tempered steel construction increases hardness and durability while the polished chromium finish improves corrosion resistance and simplifies cleaning. As a single-piece metric 5 mm Allen key, it is lightweight and easy to store in a toolbox or pocket. The precisely machined hex profile ensures a snug fit on fastener heads, reducing the likelihood of rounding or slipping during use.
Suitable for
Tightening and loosening M5-sized hex fasteners on furniture and fittings
Routine maintenance and repairs on bicycles and small machinery
Assembly and disassembly tasks in workshops and home DIY projects
Key specifications
Tool type: single-piece metric hex (Allen) key
Size: 5 mm
Material treatment: quenched and tempered steel
Surface finish: polished chromium
Design: straight shank, single end
How to use
Insert the 5 mm hex key fully into the hex recess of the fastener to ensure full contact between tool and head. Apply steady turning force, using the longer length of the key for increased leverage when loosening tight fasteners and the shorter side for controlled tightening. Avoid excessive force that could damage the fastener head; if a fastener is seized, apply penetrating lubricant and allow time to work before attempting to turn again.
Usage recommendations
Store the hex key in a dry place to preserve the polished chromium finish. Use the correct 5 mm size to prevent rounding of fastener heads and inspect the tool for worn edges before use; replace if the profile shows deformation.
