Hex Allen Key 12 mm GEKO G11712 — L-shaped hex wrench, 180 mm length

GEKO G11712 is a single-piece L-shaped hex (Allen) key with a 12 mm tip and an overall length of 180 mm. Manufactured from hardened steel, this tool is designed to engage hex-socket fasteners and provide improved reach and leverage compared to short keys. Its L-shape offers two working positions: a long arm for reach and a short arm for higher torque, making it suitable for routine assembly, maintenance and repair tasks.

Advantages

The L-shaped geometry delivers a balance between access and torque, enabling use in confined spaces and on deeper-set fasteners. Constructed from a single hardened steel piece, the key resists bending under typical torque loads and provides reliable contact with hex sockets. The 180 mm overall length increases reach while preserving user control, and the 12 mm size fits a wide range of common hardware used in furniture assembly and mechanical equipment.

Suitable for

• Furniture assembly and adjustment
• Mechanical repairs and maintenance
• Tightening and loosening 12 mm hex-socket bolts in confined or recessed areas
• Workshop and home DIY tasks requiring extended reach or higher leverage

Key specifications

• Hex tip size: 12 mm
• Shape: L-shaped (Allen key)
• Total length: 180 mm
• Construction: single-piece hardened steel
• Finish: matte or corrosion-resistant coating (manufacturer typical finish)

How to use

Insert the 12 mm hex tip fully into the hex-socket fastener to ensure a secure fit and prevent rounding. Use the short arm of the L-shape when greater torque is required and the long arm when additional reach is needed. Apply steady, controlled force and avoid sudden torque spikes. When working in restricted spaces, orient the long arm to access recessed bolts while using the short arm for turning. After use, wipe the tool clean and store it in a toolbox or holder to prevent corrosion and maintain tip geometry.

Usage recommendations

For best performance, ensure the hex socket and key are free of debris before use and select the short arm for higher torque applications. Do not use the key as a pry bar or hammer; follow standard safety practices and wear eye protection when working with fasteners under tension.
