BOSCH Professional Hex Key Set, 9 Pieces, 1.5–10 mm

The Bosch Professional Hex Key Set, 9 Pieces, 1.5–10 mm is a manually operated collection of L-shaped Allen keys for tightening and loosening hex socket screws. The set covers nine metric sizes across the 1.5 mm to 10 mm range, and the screw socket must match one of the supplied keys. Operation is entirely by hand, so the set does not require a battery, charger or mains connection. It is intended for assembly, maintenance, repair and adjustment work on standard hex socket fasteners.

The set is specified for professional workshops, on-site applications and home workshops. Workshop tasks include routine assembly, servicing and repair work on hex socket screws. For on-site use, the manual format avoids dependence on an electrical supply. Home users can also use the keys for DIY tasks and equipment adjustments. Each key is used in the same way, with the appropriate size selected for the socket.

• Hardened S2 steel construction for repeated fastening and loosening work.
• Ball-ended tips for access to screws in confined or awkward positions.
• Shafts designed to resist rounding during use.
• 360 g total weight keeps the complete set portable.
• Key length provides leverage when applying or releasing torque.
