Hex Key Set Dedra 06F205 extra-long S2 steel 1.5–10 mm, 9-piece colored

Dedra 06F205 is a 9-piece extra-long hex key set crafted from S2 tool steel, covering metric sizes from 1.5 mm to 10 mm. The extended shaft length provides extra reach for recessed or hard-to-access hex fasteners while maintaining torsional strength. Each key features color-coded identification to speed up size selection and reduce downtime during mechanical, assembly or maintenance work.

Advantages

The S2 tool steel construction gives improved hardness and wear resistance compared with standard carbon allen keys, offering longer service life under repeated torque. The extra-long design allows access to deep-set screws and bolts without the need for adapters or extensions. Color coding on each key simplifies size recognition in busy toolboxes or on the workbench, increasing workflow efficiency and reducing errors.

Suitable for

• Accessing recessed or deep-set hex fasteners in mechanical assemblies
• Assembly and disassembly of furniture, machinery, and equipment
• Maintenance tasks in automotive, bicycle repair and industrial settings
• Workshop and hobby use where extended reach is required

Key specifications

• Material: S2 tool steel for enhanced durability and wear resistance
• Set configuration: 9 pieces, extra-long shafts for extended reach
• Size range: metric 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm
• Finish: colored identification for quick size selection

How to use

Select the hex key that matches the hex socket size of the fastener and insert the short or long end as required to obtain the best leverage or reach. For deep or recessed fasteners use the extra-long shaft to access the head while keeping the handle clear. Apply steady torque aligned with the fastener axis to avoid cam-out or rounding. After use, clean any debris from the tool and store the set in its holder or toolbox to preserve the color markings and prevent corrosion.

Usage recommendations

Use appropriate hand force only; avoid striking the hex keys with hammers or using them as prying bars. For higher torque requirements consider using the short end for leverage or a larger sized key. Keep tools dry and free from corrosive substances to maintain S2 steel performance and the integrity of color coding.
