## Summary description

Proline 48520 is a single metric hex key sized 2.5 mm. Designed for tightening and loosening hex-head fasteners in mechanical assemblies, electronics and DIY repairs, this compact L-shaped tool provides access to confined spaces and precise torque control for small screws and bolts.

## Long description

Proline 48520 is a single metric hex key with a 2.5 mm tip, designed for precise tightening and loosening of hex-head fasteners. The compact L-shaped tool offers good reach and torque control for small screws and bolts encountered in mechanical assemblies, electronics repair and general DIY tasks. Its small size allows access to confined spaces while maintaining a firm grip on fastener heads to reduce slipping and rounding.
Advantages
The hex key is made to standard metric dimensions for reliable fit with 2.5 mm hex sockets, ensuring accurate torque transfer. Its L-shaped profile provides both leverage and a short-end option for confined spaces. The single-piece design keeps the tool simple and lightweight, making it convenient to store in a toolbox or carry in a pocket. The rigid construction minimizes flex during use for consistent performance on small fasteners.
Suitable for
 Assembly and disassembly of mechanical components with 2.5 mm hex fasteners
 Electronics repair and maintenance where compact tools are required
 DIY projects involving furniture, bicycles, or household hardware using small hex screws
 Tightening and adjustment tasks in confined or hard-to-reach areas
Key specifications
 Tip size: 2.5 mm (metric)
 Tool type: L-shaped hex key (Allen key)
 Quantity: 1 piece
 Typical applications: mechanical assemblies, electronics, DIY repairs
 Construction: single-piece rigid design for minimal flex
How to use
Insert the 2.5 mm tip fully into the hex recess of the fastener to ensure a secure engagement. Use the long arm for greater leverage when loosening or tightening, or flip the key to use the short arm for access in tight spaces. Apply steady, controlled force to avoid stripping the fastener head; for precision work, make small incremental turns and check the fastener seating frequently. Keep the hex key clean and free of debris to maintain proper fit.
Usage recommendations
Use the appropriate hand position to control torque and avoid over-tightening small fasteners. When working on delicate electronics or precision components, combine the hex key with torque-limiting techniques or a torque driver suitable for 2.5 mm hex bits. Store the tool in a dry place to prevent corrosion and inspect the tip for wear before critical tasks.
