Hex key set Tvardy long S2 9 pcs 1.5–10 mm colored

Long hex key set Tvardy S2, 9 pcs, sizes 1.5–10 mm, provides a range of metric Allen keys designed for tasks that require extended reach and improved leverage. Each key is manufactured from S2 tool steel and formed in a long-shaft shape to access recessed or hard-to-reach hex fasteners. The set is color-coded to enable quick visual identification of sizes and is packaged together for organized storage and transport.

Advantages

The long-shaft design offers better access to deep-seated hex fasteners and increased torque compared with short keys. S2 tool steel construction ensures durability and resistance to wear under regular use. Color coding on each key reduces time spent selecting the correct size and minimizes errors during assembly or repair. The compact set of nine sizes covers common metric hex dimensions from 1.5 mm to 10 mm, making it a versatile option for a variety of applications.

Suitable for

• Assembly and disassembly of furniture with metric hex fasteners
• Bicycle maintenance and adjustments requiring extended reach
• Servicing machinery and equipment with recessed hex bolts
• General workshop, DIY and repair tasks involving metric Allen screws

Key specifications

• Material: S2 tool steel for enhanced strength and wear resistance
• Set composition: 9 long hex keys covering sizes 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm
• Length: long type shafts for improved reach and leverage
• Finish: colored coating for size identification
• Drive type: metric hex (Allen) profile

How to use

Select the key with the color or size marking that corresponds to the hex fastener. Insert the long end into the fastener head to engage the profile fully, ensure a secure fit to avoid rounding, and apply steady torque. Use the extended shaft when access is limited or when additional leverage is required; switch to the short end of the key if a compact turning radius is needed. After use, return the keys to their holder or storage location to maintain organization and prevent loss.

Usage recommendations

Inspect keys regularly for wear or deformation. Match the key size precisely to the fastener to prevent rounding; do not use damaged keys. For high-torque applications, use appropriate torque tools or longer handles designed for such loads rather than applying excessive force to individual keys.
