Hex Allen Key 3 mm GEKO model 600 — 3 mm hexagonal L-key

GEKO model 600 3 mm hex (Allen) key is a single-piece L-shaped tool engineered for driving fasteners with a 3 mm internal hex. Made from steel, this compact L-key transfers torque efficiently for tightening and loosening hex screws in confined spaces. Its simple design is suited to routine assembly, maintenance and repair work where a reliable 3 mm hex drive is required.

Advantages

The one-piece steel construction delivers consistent torque transfer and durability for repeated use. The L-shaped form offers two leverage options: a short arm for high-torque operations and a long arm for reach and leverage in tighter clearances. The compact size makes it easy to store in tool rolls, pockets or toolboxes, and its standardized 3 mm hex profile ensures compatibility with common internal-hex fasteners.

Suitable for

• Assembling and adjusting bicycles and small machinery
• Furniture assembly and household repairs
• Electronics enclosures and small appliance maintenance
• Workshop and field service tasks requiring a 3 mm hex drive

Key specifications

• Tool type: L-shaped hex (Allen) key
• Size: 3 mm hexagonal tip
• Material: steel construction for torque transfer
• Design: single-piece, angled L-key for dual-leverage use
• Finish: plain or corrosion-resistant coating depending on batch

How to use

Insert the 3 mm hex tip fully into the internal hex socket of the fastener to ensure proper engagement and avoid rounding the screw head. Use the short arm of the L-key when higher torque is needed; use the long arm for greater reach or finer control. Apply steady, even force while turning to tighten or loosen the fastener. Inspect the key and fastener for wear before use and replace the tool if the tip becomes rounded or damaged.

Usage recommendations

For best results, keep the hex key clean and dry and store it in a designated holder to prevent tip wear. When working on sensitive components, use controlled torque and avoid excessive force to protect fasteners and surrounding parts.
