## Summary description

Proline 48442 is a single-piece metric hex key (Allen key) with a 2 mm tip. Designed for driving hexagonal socket screws and fasteners, this compact tool is suitable for light assembly, electronics, bicycle adjustments and general household repair tasks requiring a small 2 mm hex driver.

## Long description

Proline 2 mm hex key model 48442 is a single-piece metric Allen key designed for driving hexagonal socket screws and fasteners with a 2 mm tip. Made from quenched and tempered steel and finished with polished chromium, this compact hand tool provides a precise fit for small hex fasteners commonly found in electronics, bicycles, appliances and furniture. Its single-piece design ensures consistent alignment and torque transmission when accessing tight or recessed fasteners.
Advantages
The hardened and tempered construction improves durability and resistance to bending during regular use. A polished chromium finish reduces surface corrosion and allows the tool to slide smoothly in confined spaces. The single-piece shape offers stable handling and a reliable contact profile on 2 mm hex sockets, minimising rounding of screw heads when used correctly.
Suitable for
Electronics assembly and maintenance
Bicycle adjustments and brake/derailleur tuning
Small household repairs and furniture assembly
Model building and precision mechanical work
Key specifications
Tip size: 2 mm hex (metric)
Design: single-piece Allen key
Material treatment: quenched and tempered steel
Finish: polished chromium
Application: manual hand tool for hex socket screws
How to use
Insert the 2 mm tip fully into the hex socket of the fastener to ensure maximum contact. Apply steady, even torque while maintaining alignment between the key and the screw head to avoid slippage or rounding. For stubborn fasteners, use controlled incremental force rather than sudden high torque. After use, wipe the tool clean and store it in a dry place to preserve the polished finish.
Usage recommendations
Use the 2 mm hex key only with matching hex socket fasteners and avoid excessive torque beyond the fastener's capacity. Regularly inspect the tip for wear and replace if the profile becomes rounded to prevent damage to screw heads. Store the tool away from moisture to maintain the chromium finish and prevent corrosion.
