Hex Key Set Cyclo CYC-7774 — Socket Head Allen Keys (hexagon keys)

Cyclo CYC-7774 is a compact set of socket head Allen keys designed for tightening and loosening hexagonal socket screws. The set includes a range of common sizes specified by the manufacturer to cover general repair, assembly and maintenance tasks. The tools are intended for use in workshop environments and portable toolkits, providing straightforward access to fasteners in bicycles, furniture, machinery and electronic devices.

Advantages

The set combines multiple hex key sizes in a single compact kit, reducing the need to carry individual loose keys. Socket head (hexagon) ends provide positive engagement with hex socket screws, which helps reduce cam-out and rounding of fastener heads. The keys are manufactured to provide consistent dimensions for reliable fit and torque transfer. Their compact arrangement supports organized storage and easy selection of the required size.

Suitable for

• Maintenance and assembly of bicycles and e-bikes
• Furniture assembly and adjustments
• Light machinery and equipment repairs
• Servicing household electronics and appliances

Key specifications

• Tool type: socket head Allen keys (hexagon keys)
• Set composition: multiple metric sizes included (manufacturer-specified range)
• Material: heat-treated steel for strength and wear resistance
• Finish: corrosion-resistant coating to extend service life
• Storage: compact holder for organized transport and access

How to use

Select the hex key size that fits securely into the hex socket of the screw. Insert the key fully into the socket to ensure maximum contact surface, then apply steady torque in the required direction—clockwise to tighten, counterclockwise to loosen. For stuck or rusted fasteners, use controlled, incremental force and avoid excessive leverage that could shear the screw head. Return keys to their holder after use to maintain organization and protect the tool surfaces.

Usage recommendations

Use the correct key size to prevent damage to fastener heads. Keep the set dry and clean, and periodically apply a light lubricant to the hinge or holder mechanism if present. When working on precision electronics or delicate finishes, apply torque carefully and consider using a torque-limiting driver where appropriate.
