Hex Y-wrench set Cyclo CYC-6318 — 2 mm / 2.5 mm / 3 mm

Cyclo CYC-6318 is a Y-shaped Allen key set featuring fixed 2 mm, 2.5 mm and 3 mm hex arms designed for compact hand-held use. The Y-wrench layout gives a three-point grip that improves leverage and control when working with small hex fasteners. Single-piece construction and clearly marked arm sizes allow rapid selection and dependable tightening of M2–M3 range fasteners in bicycles, small machines and electronic assemblies.

Advantages

The fixed-arm Y-design concentrates torque at the tool’s intersection while keeping each hex key rigid for repeatable performance. Durable single-piece construction reduces play and the risk of arm loosening. The compact form factor fits into tool rolls, pocket organizers and small toolkits, while the distinct arm lengths help reach recessed fasteners and provide additional leverage when needed.

Suitable for

• Bicycle maintenance and on-bike adjustments
• Small machinery servicing and assembly
• Electronics assembly and component fastening
• Hobbyist projects requiring M2–M3 hex fasteners

Key specifications

• Tool type: Y-shaped hex key (Allen) set with fixed arms
• Hex sizes: 2 mm, 2.5 mm, 3 mm
• Construction: single-piece metal body for rigidity
• Grip: three-arm Y layout for increased leverage and control
• Form factor: compact handheld design suitable for pockets and small tool kits

How to use

Select the arm with the matching hex size and insert the hex tip fully into the fastener head to ensure proper contact. Use the short arm for higher torque and the long arm for reach or finer control. Apply steady force perpendicular to the fastener face and avoid excessive twisting beyond the fastener’s torque rating. After use, wipe the tool clean and store it in a dry place to prevent corrosion.

Usage recommendations

For bicycle and precision work, check fastener compatibility before applying high torque. Use the 2 mm and 2.5 mm arms for smaller screws and the 3 mm arm for slightly larger M3 fasteners; inspect fastener heads for wear to prevent rounding.
