BOSCH 9-Piece Hex Key Set with Colour-Coded L-Keys, Ball End and Holding Function, Metric 1.5-10 mm, BlackLaser Finish, Clip Holder

Unlike ordinary L-key assortments, this BOSCH set combines colour-coded sizing, ball-end long arms, and a built-in holding function that grips hexagon socket screws securely. Nine metric keys cover the most common fastener sizes, while the BlackLaser surface treatment adds corrosion resistance for long-term reliability in workshops, on job sites, or at home.

Highlights

• 9-piece metric set: 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 mm
• Ball end on the long arm allows angled access up to 25° for hard-to-reach screws
• Holding function (SM N) firmly grips hexagon socket screws, preventing them from falling during positioning
• Colour-coded keys and laser-engraved size markings for instant identification
• BlackLaser finish protects against corrosion and extends tool life
• Wear-resistant clip holder keeps the set organised and portable

In daily use

Assembling furniture, adjusting machinery, or performing precision repairs — this set delivers the versatility needed for both high-torque and confined-space tasks. The long arm provides excellent leverage for loosening or tightening, while the short arm fits into tight recesses. The ball end is particularly useful when working at an angle, and the holding function ensures screws stay on the key until you are ready to drive them. The compact clip holder slides easily into a pocket or tool bag, and the colour coding saves time when selecting the correct size.
