Hex key Proline 3 mm – model 48462, single-piece L-shaped Allen key

Proline hex key 3 mm (model 48462) is a single-piece L-shaped Allen key made of quenched and tempered steel with a polished chromium finish. Designed for metric 3 mm hex socket fasteners, this compact tool provides controlled torque and reliable engagement for assembly, maintenance, bicycle repair and furniture fitting tasks. Its L-shaped design offers a short and a long arm to balance access and leverage in confined and open spaces.

Advantages

The solid one-piece construction ensures consistent strength and resistance to bending, while the quenched and tempered steel delivers improved hardness and wear resistance. The polished chromium finish protects against corrosion and allows smoother insertion into sockets. The combination of short and long arms gives a choice of higher torque or increased reach without additional tools.

Suitable for

• Tightening and loosening metric 3 mm hex socket bolts and screws
• Bicycle maintenance and adjustments in confined areas
• Furniture assembly and domestic repairs
• Workshop tasks requiring a compact, durable hex key

Key specifications

• Tool type: L-shaped single-piece hex key (Allen key)
• Size: 3 mm metric hex

How to use

Select the 3 mm hex key and insert the appropriate arm into the hex socket of the fastener until fully seated. Use the short arm inward for greater torque when loosening or tightening, or use the long arm for increased reach and access in confined spaces. Apply steady, controlled force to avoid rounding the fastener head. After use, wipe the tool clean and store it in a toolbox or holder to prevent corrosion and damage.

Usage recommendations

For best results, match the 3 mm Proline hex key precisely to the fastener size, avoid excessive force that could deform the hex socket, and keep the tool dry and clean to preserve the polished chromium finish and material properties.
