Hex L‑key Allen wrench Bondhus 3 mm — L‑shaped hex key (model 13856)

The Bondhus 3 mm L‑shaped hex key is a single-piece Allen wrench designed for driving 3 mm internal hex fasteners. Its compact L‑shape offers a short end for high torque and a long end for reach, making it suitable for assembly, maintenance and repair tasks across mechanical, electronic and furniture applications. Constructed for consistent fit and straightforward manual operation, this hex key is intended as a basic hand tool for situations that require a durable, precise hex driver.

Advantages

The one-piece construction provides rigidity and reliable contact with hex fasteners, reducing rounding of screw heads. The L‑shaped design gives two useful leverage options: the short leg for higher torque and the long leg for access to recessed or hard-to-reach fasteners. Its compact size is convenient for storage and transport and for working in confined spaces. The tool’s straightforward geometry ensures consistent engagement with 3 mm hex sockets for repeatable performance in routine tasks.

Suitable for

• Assembly and disassembly of furniture and fittings
• Maintenance and repair of small mechanical devices
• Electronics service where 3 mm internal hex fasteners are used
• Tight spaces and recessed fasteners requiring extended reach

Key specifications

• Tool type: L‑shaped hex (Allen) key
• Hex size: 3 mm
• Construction: single-piece solid hex key
• Drive style: manual, two-leg leverage (short and long arm)
• Typical applications: mechanical, electronics, furniture assembly and maintenance

How to use

Select the 3 mm end that provides the required torque and reach. Insert the appropriate hex end fully into the internal hex recess of the fastener to ensure full contact and avoid cam‑out. Use the short leg as the driver for higher torque applications and the long leg when additional reach or clearance is needed. Apply steady, controlled force and avoid sudden impact loads. After use, store the hex key in a tool holder or designated compartment to keep it protected and to prevent loss.

Usage recommendations

Use the short arm for tightening or loosening high‑torque fasteners and the long arm when access is limited. Inspect the contact surfaces before use; replace the tool if significant wear or rounding appears to maintain safe and reliable engagement with 3 mm hex fasteners.
