## Summary description

Proline Tools 48574 is a single-piece metric hex key sized 10 mm for driving hex fasteners.

## Long description

Proline 48574 is a single-piece metric 10 mm hex key designed for driving hexagonal socket screws and bolts. Manufactured by Proline for manual fastening and loosening tasks, this tool is intended for general maintenance, installation and repair work where a compact, robust hand tool is required. The hex key is heat-treated and tempered for strength, with a polished chromium finish that improves corrosion resistance and provides a smooth surface for handling.
Advantages
The single-piece construction offers dimensional stability and consistent torque transfer when turning fasteners. Heat treatment and tempering increase hardness and reduce the risk of deformation under load. The polished chromium finish gives enhanced protection against corrosion and makes the tool easier to clean after use. Its compact form factor allows access to confined spaces and simple storage in tool rolls or pockets.
Suitable for
Assembling and disassembling machinery and equipment with 10 mm hex sockets
Furniture assembly and joinery that use metric hex bolts
Maintenance and repair tasks in workshops, garages and technical service jobs
Field service applications where a durable, single-piece hand tool is needed
Key specifications
Type: single-piece metric hex key (allen key)
Size: 10 mm across flats
Material treatment: quenched and tempered for increased hardness
Surface finish: polished chromium for corrosion resistance
Drive: hexagonal socket driver for internal hex fasteners
How to use
Select the 10 mm hex key and insert the short or long end into the hex socket of the screw or bolt until it seats fully. Apply steady, controlled force to turn the key clockwise to tighten or counterclockwise to loosen, taking care to keep the tool aligned with the fastener to avoid rounding the socket. For higher torque, use the longer arm for increased leverage; for restricted spaces, use the shorter arm. Inspect the tool and fastener before use to ensure a correct fit and avoid slippage.
Usage recommendations
Do not apply impact forces or use the hex key as a pry bar. Clean and dry the tool after use and store in a dry location to maintain the polished chromium finish. Replace the hex key if the edges of the hex show rounding or excessive wear to prevent damage to fasteners.
