## Long description

Proline 4 mm hex key 48529 is a single L-shaped metric Allen wrench made of hardened steel for driving and loosening 4 mm hex-head fasteners. The compact L-shape provides a short and long arm for different leverage needs and access to recessed or hard-to-reach fasteners. This tool is intended for assembly, maintenance and repair tasks where a 4 mm hex interface is required, offering a straightforward and reliable solution for home, workshop and professional use.
Advantages
The L-shaped design delivers two working lengths that allow controlled torque application and reach into confined spaces. Hardened steel construction improves wear resistance and maintains hex profile fit over repeated use, reducing rounding of fasteners. The single-piece design has no moving parts, which increases durability and simplifies storage and transport.
Suitable for
Furniture assembly and disassembly
Bicycle maintenance and component adjustment
Small machinery and equipment repairs
Electronics enclosures and fixtures with 4 mm hex fasteners
General household maintenance tasks
Key specifications
Tool type: L-shaped metric hex key (Allen wrench)
Size: 4 mm hex drive
Material: hardened steel
Design: single-piece, L-shaped with short and long arm
Finish: corrosion-resistant surface treatment (factory applied)
How to use
Select the 4 mm hex key and insert the short or long arm into the hex socket of the fastener depending on desired leverage and clearance. Use the long arm for higher torque and the short arm for greater access and tighter spaces. Apply steady, controlled force to avoid stripping the fastener head; reverse the motion to loosen. When working on multiple fasteners, organize them and check engagement to ensure the hex key seats fully before applying torque.
Usage recommendations
Inspect the hex key and fastener for wear before use. For tasks requiring higher torque, use the long arm and keep force within the tool’s capacity to prevent bending. Store the tool in a dry place and clean contact surfaces after use to maintain fit and reduce corrosion.
