Allen key (hex) 11 mm GEKO model G11711, length 180 mm

Fixed 11 mm hex (Allen) key from GEKO, model G11711 with a 180 mm length. This single-piece steel hand tool is designed to engage hexagonal socket fasteners and transfer manual torque for tightening and loosening. The long arm provides reach into recessed or angled fittings, while the one-piece construction maintains alignment and strength during routine automotive, bicycle, furniture assembly and general maintenance tasks.

Advantages

The 11 mm hex shape matches standard internal hex fasteners for reliable engagement and reduced cam-out. Solid steel construction offers rigidity and durable torque transfer for manual use. The 180 mm length increases reach and leverage compared with short keys, allowing access to recessed sockets and making it easier to apply turning force in confined spaces.

Suitable for

• Automotive fastener adjustments and minor repairs
• Bicycle maintenance and component assembly
• Furniture assembly and household fittings
• General workshop and maintenance tasks requiring an 11 mm internal hex

Key specifications

• Hex size: 11 mm
• Material: steel construction for manual torque transfer
• Length: 180 mm overall
• Design: fixed one-piece L-shaped hex key

How to use

Select the 11 mm hex end that fully engages the fastener recess, insert the short or long arm as needed to achieve the best access and leverage, and apply steady manual torque to tighten or loosen. Use the long arm for reach into recessed sockets and the short arm for higher torque. Ensure full contact between tool and fastener to avoid rounding the hex. Inspect the tool for wear or deformation before use.

Usage recommendations

For safe and effective results, use the Allen key with controlled force suitable for hand tools only; avoid excessive impact or use with power tools. Keep the tool clean and store it dry to limit corrosion. When working on critical fastenings, verify fit and torque according to manufacturer specifications.
