Hex key set GEKO 9-piece CrV 1.5–10 mm, colored handles

GEKO 9-piece hex key set includes L-shaped Allen keys in chrome vanadium (CrV) steel, covering metric sizes from 1.5 mm up to 10 mm. Each key is fitted with a colored handle for faster size recognition and a more comfortable grip. The compact set is intended for general tightening and loosening of hex fasteners in mechanical work, bicycle maintenance, furniture assembly and household repairs.

Advantages

The CrV construction provides increased strength and wear resistance compared to standard carbon steel, while the precision-formed hex profiles ensure secure contact with fasteners and reduced rounding. Colored handles allow quick visual identification of sizes and improve handling in confined spaces. The L-shaped design supplies both torque and reach options for varied access angles.

Suitable for

• Assembly and disassembly of furniture and fittings
• Bicycle maintenance and component adjustments
• Mechanical and light industrial fastening tasks
• General DIY repairs and home workshop use

Key specifications

• Material: chrome vanadium (CrV) steel
• Set composition: 9 hex keys
• Size range: 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm
• Handle: colored grip on each key for size identification
• Shape: L-shaped keys (short and long arm)

How to use

Select the hex key that matches the fastener size and insert the short or long arm into the screw recess to suit access and leverage needs. Apply steady turning force, keeping the key aligned with the fastener to avoid slippage and rounding. Use the long arm for reach and the short arm for higher torque when loosening or tightening hex screws.

Usage recommendations

For reliable results, match the correct key size to the fastener, avoid excessive force that can damage both key and fastener, and store the set in a dry place to prevent corrosion. For high-torque industrial applications, consider tools specifically rated for impact or torque-limiting use.
