## Summary description

Proline 48378 is an 8-piece hex key (Allen key) set designed for driving hexagonal socket screws. The set includes eight L-shaped keys in varying sizes, made of steel for general fastening and assembly tasks. Suitable for workshop, home repairs and mechanical maintenance where compact, manual hex tools are required.

## Long description

Proline 48378 is an 8-piece L-shaped hex key set made of steel for driving hexagonal socket screws. The set contains keys in sizes 1.5, 2, 2.5, 3, 4, 5, 6 and 8 mm, designed for general fastening, assembly and maintenance tasks where compact manual hex tools are required. Each key has a long and a short arm to give access in confined spaces and increased leverage when needed.
Advantages
Keys are manufactured from abrasion- and twist-resistant steel for reliable torque transfer and long service life. Each tool features a metal ferrule covered with soft plastic at the handle area to improve grip and protect the ferrule. The L-shape design allows use at up to a 30° angle to the bolt axis so you can reach fasteners that are slightly offset. The set covers common metric sizes for workshop and household use, providing a compact, organised selection.
Suitable for
Tightening and loosening hex socket screws in machinery and equipment
Home repairs and furniture assembly where manual hex keys are needed
Maintenance and adjustments in automotive, bicycle and small engine work
Use in workshops, toolboxes and portable repair kits
Key specifications
Material: abrasion- and twist-resistant steel
Set size: 8 pieces
Included key sizes: 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm
Design: L-shaped (long and short arm)
Ferrule: metal ferrule with soft plastic cover for improved grip
Angular access: usable at up to 30° to the bolt axis
How to use
Select the hex key that fits snugly into the hexagonal socket of the fastener. Insert the short arm for better access in tight spaces or use the long arm to increase leverage. Apply steady torque and avoid sudden excessive force to prevent rounding the socket or damaging the tool. If angle access is needed, position the key up to 30° off-axis while maintaining full engagement of the drive surfaces.
Usage recommendations
Store the keys in their set to prevent loss and to keep sizes organised. Clean and lightly oil the tools after use in corrosive environments. For higher torque requirements, use the long arm for leverage rather than applying excessive force to the short arm to reduce risk of tool deformation or screw damage.
