Hex ball-end hex key set Dedra 06F215 S2 steel 1.5–10 mm, 9-piece

Dedra 06F215 is a 9-piece set of long ball-end hex keys manufactured from S2 steel, covering metric sizes from 1.5 to 10 mm. The ball-end geometry enables angled engagement with fasteners, making it easier to reach screws in confined or obstructed locations. Long arms provide added reach and mechanical advantage for assembly, maintenance and repair tasks on furniture, bicycles, machinery and electronic devices that use hex fasteners.

Advantages

The S2 steel construction offers increased hardness and wear resistance for frequent use. Ball-end tips permit up to approximately 25–30° of angular entry, improving access to recessed or awkwardly positioned fasteners. Long-arm design increases leverage for loosening and tightening, while the straight shank sections help maintain alignment and reduce cam-out. The set format includes a wide range of commonly used metric sizes, eliminating the need to switch tools during most jobs.

Suitable for

• Assembly and installation of furniture with metric hex fasteners
• Bicycle maintenance and component fittings
• General workshop and machinery adjustments
• Electronics repair where compact, angled access is required
• Automotive interior and trim fastening using metric hex bolts

Key specifications

• Material: S2 tool steel for improved strength and durability
• Tip style: Ball-end for angled engagement with fasteners
• Range of sizes: 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm
• Geometry: Long-arm design for extended reach and leverage
• Finish: Machined/black oxide or similar corrosion-resistant surface treatment

How to use

Select the hex key that matches the fastener size to ensure a snug fit. For standard engagement, insert the short or long end straight into the hex socket and apply steady torque. When access is restricted, use the ball-end at an angle—this allows entry when the fastener is not perfectly aligned with the tool. Apply controlled force to avoid rounding the fastener head; if resistance is unusually high, verify correct size and inspect both tool tip and fastener for damage.

Usage recommendations

Store the keys in a holder or toolbox to protect tips and maintain organization. Avoid using excessive impact or leverage beyond the tool's capacity to reduce risk of tip deformation. Periodically clean and lightly oil the tools to prevent corrosion and extend service life.
