Long Hex Key 8.0 mm YT-05440 YATO
A hexagonal hex key, size 8 mm, in a long-reach version, made from chrome vanadium steel. Designed for workshop, service and assembly work requiring access to deeply recessed hex socket screws.
Features of the 8 mm long hex key
Long-reach design
The long shaft allows work in deep holes and hard-to-reach places where standard keys cannot reach. It also increases torque when tightening screws that require greater force.
Chrome vanadium steel
CrV material offers increased hardness and wear resistance. Hardened tips ensure that the precise working edges are retained for a long time, minimising the risk of the tip rounding off.
Precise 8 mm fit
The 8 mm size is one of the standard hex socket screw sizes used in mechanical work, furniture making and steel structures. Precise manufacturing ensures a full fit against the walls of the hex socket.
Versatile applications
The key is ideal for automotive workshops when removing components fastened with hex socket screws, for equipment servicing, and for assembling furniture fitted with hex socket connectors.

Applications of the 8 mm hex key
- Repair and maintenance of motor vehicles - removal of suspension and braking system components
- Servicing industrial machinery and equipment fitted with M10-M12 hex socket screws
- Assembly and adjustment of office and kitchen furniture with a hex connector system
- Bicycle work - adjusting stems, seat posts and handlebar clamps
- Hydraulic and pneumatic installations requiring access to deeply recessed screws
- Assembly of steel and aluminium structures with hex bolted connections
- Workshop tasks requiring increased torque when tightening
How to check compatibility
The 8 mm size corresponds to the inscribed diameter of the screw's hex socket. It is most commonly used with M10-M12 cap head screws. Before use, check that the key enters the socket freely without play - too much play can damage the screw edges during tightening.
Use and maintenance
Hex keys made from chrome vanadium steel require basic maintenance to retain their working properties. After use, remove any dirt and oil residue. Storing them in a dry place prevents surface corrosion.
During use, avoid extensions that increase leverage beyond the recommended torque values - this can permanently deform the key. For seized screws, apply a penetrating fluid before attempting to undo them.
Difference between a long and a standard key
The long version has an extended shaft, which increases reach and torque. Standard hex keys have a shorter design, suitable for work in easily accessible places. The choice depends on how deeply the screw is recessed and the tightening force required.
